Definition and Introduction

Case analysis is a problem-based teaching and learning method that involves critically analyzing complex scenarios within an organizational setting for the purpose of placing the student in a “real world” situation and applying reflection and critical thinking skills to contemplate appropriate solutions, decisions, or recommended courses of action. It is considered a more effective teaching technique than in-class role playing or simulation activities. The analytical process is often guided by questions provided by the instructor that ask students to contemplate relationships between the facts and critical incidents described in the case.

Cases generally include both descriptive and statistical elements and rely on students applying abductive reasoning to develop and argue for preferred or best outcomes [i.e., case scenarios rarely have a single correct or perfect answer based on the evidence provided]. Rather than emphasizing theories or concepts, case analysis assignments emphasize building a bridge of relevancy between abstract thinking and practical application and, by so doing, teaches the value of both within a specific area of professional practice.

Given this, the purpose of a case analysis paper is to present a structured and logically organized format for analyzing the case situation. It can be assigned to students individually or as a small group assignment and it may include an in-class presentation component. Case analysis is predominately taught in economics and business-related courses, but it is also a method of teaching and learning found in other applied social sciences disciplines, such as, social work, public relations, education, journalism, and public administration.

How to Approach Writing a Case Analysis Paper

The organization and structure of a case analysis paper can vary depending on the organizational setting, the situation, and how your professor wants you to approach the assignment. Nevertheless, preparing to write a case analysis paper involves several important steps. As Hawes notes, a case analysis assignment “...is useful in developing the ability to get to the heart of a problem, analyze it thoroughly, and to indicate the appropriate solution as well as how it should be implemented” [p.48]. This statement encapsulates how you should approach preparing to write a case analysis paper.

Before you begin to write your paper, consider the following analytical procedures:

• Review the case to get an overview of the situation . A case can be only a few pages in length, however, it is most often very lengthy and contains a significant amount of detailed background information and statistics, with multilayered descriptions of the scenario, the roles and behaviors of various stakeholder groups, and situational events. Therefore, a quick reading of the case will help you gain an overall sense of the situation and illuminate the types of issues and problems that you will need to address in your paper. If your professor has provided questions intended to help frame your analysis, use them to guide your initial reading of the case.
• Read the case thoroughly . After gaining a general overview of the case, carefully read the content again with the purpose of understanding key circumstances, events, and behaviors among stakeholder groups. Look for information or data that appears contradictory, extraneous, or misleading. At this point, you should be taking notes as you read because this will help you develop a general outline of your paper. The aim is to obtain a complete understanding of the situation so that you can begin contemplating tentative answers to any questions your professor has provided or, if they have not provided, developing answers to your own questions about the case scenario and its connection to the course readings,lectures, and class discussions.
• Determine key stakeholder groups, issues, and events and the relationships they all have to each other . As you analyze the content, pay particular attention to identifying individuals, groups, or organizations described in the case and identify evidence of any problems or issues of concern that impact the situation in a negative way. Other things to look for include identifying any assumptions being made by or about each stakeholder, potential biased explanations or actions, explicit demands or ultimatums , and the underlying concerns that motivate these behaviors among stakeholders. The goal at this stage is to develop a comprehensive understanding of the situational and behavioral dynamics of the case and the explicit and implicit consequences of each of these actions.
• Identify the core problems . The next step in most case analysis assignments is to discern what the core [i.e., most damaging, detrimental, injurious] problems are within the organizational setting and to determine their implications. The purpose at this stage of preparing to write your analysis paper is to distinguish between the symptoms of core problems and the core problems themselves and to decide which of these must be addressed immediately and which problems do not appear critical but may escalate over time. Identify evidence from the case to support your decisions by determining what information or data is essential to addressing the core problems and what information is not relevant or is misleading.
• Explore alternative solutions . As noted, case analysis scenarios rarely have only one correct answer. Therefore, it is important to keep in mind that the process of analyzing the case and diagnosing core problems, while based on evidence, is a subjective process open to various avenues of interpretation. This means that you must consider alternative solutions or courses of action by critically examining strengths and weaknesses, risk factors, and the differences between short and long-term solutions. For each possible solution or course of action, consider the consequences they may have related to their implementation and how these recommendations might lead to new problems. Also, consider thinking about your recommended solutions or courses of action in relation to issues of fairness, equity, and inclusion.
• Decide on a final set of recommendations . The last stage in preparing to write a case analysis paper is to assert an opinion or viewpoint about the recommendations needed to help resolve the core problems as you see them and to make a persuasive argument for supporting this point of view. Prepare a clear rationale for your recommendations based on examining each element of your analysis. Anticipate possible obstacles that could derail their implementation. Consider any counter-arguments that could be made concerning the validity of your recommended actions. Finally, describe a set of criteria and measurable indicators that could be applied to evaluating the effectiveness of your implementation plan.

Use these steps as the framework for writing your paper. Remember that the more detailed you are in taking notes as you critically examine each element of the case, the more information you will have to draw from when you begin to write. This will save you time.

NOTE : If the process of preparing to write a case analysis paper is assigned as a student group project, consider having each member of the group analyze a specific element of the case, including drafting answers to the corresponding questions used by your professor to frame the analysis. This will help make the analytical process more efficient and ensure that the distribution of work is equitable. This can also facilitate who is responsible for drafting each part of the final case analysis paper and, if applicable, the in-class presentation.

Structure and Writing Style

A case analysis paper should be detailed, concise, persuasive, clearly written, and professional in tone and in the use of language . As with other forms of college-level academic writing, declarative statements that convey information, provide a fact, or offer an explanation or any recommended courses of action should be based on evidence. If allowed by your professor, any external sources used to support your analysis, such as course readings, should be properly cited under a list of references. The organization and structure of case analysis papers can vary depending on your professor’s preferred format, but its structure generally follows the steps used for analyzing the case.

Introduction

The introduction should provide a succinct but thorough descriptive overview of the main facts, issues, and core problems of the case . The introduction should also include a brief summary of the most relevant details about the situation and organizational setting. This includes defining the theoretical framework or conceptual model on which any questions were used to frame your analysis.

Following the rules of most college-level research papers, the introduction should then inform the reader how the paper will be organized. This includes describing the major sections of the paper and the order in which they will be presented. Unless you are told to do so by your professor, you do not need to preview your final recommendations in the introduction. U nlike most college-level research papers , the introduction does not include a statement about the significance of your findings because a case analysis assignment does not involve contributing new knowledge about a research problem.

Background Analysis

Background analysis can vary depending on any guiding questions provided by your professor and the underlying concept or theory that the case is based upon. In general, however, this section of your paper should focus on:

• Providing an overarching analysis of problems identified from the case scenario, including identifying events that stakeholders find challenging or troublesome,
• Identifying assumptions made by each stakeholder and any apparent biases they may exhibit,
• Describing any demands or claims made by or forced upon key stakeholders, and
• Highlighting any issues of concern or complaints expressed by stakeholders in response to those demands or claims.

These aspects of the case are often in the form of behavioral responses expressed by individuals or groups within the organizational setting. However, note that problems in a case situation can also be reflected in data [or the lack thereof] and in the decision-making, operational, cultural, or institutional structure of the organization. Additionally, demands or claims can be either internal and external to the organization [e.g., a case analysis involving a president considering arms sales to Saudi Arabia could include managing internal demands from White House advisors as well as demands from members of Congress].

Throughout this section, present all relevant evidence from the case that supports your analysis. Do not simply claim there is a problem, an assumption, a demand, or a concern; tell the reader what part of the case informed how you identified these background elements.

Identification of Problems

In most case analysis assignments, there are problems, and then there are problems . Each problem can reflect a multitude of underlying symptoms that are detrimental to the interests of the organization. The purpose of identifying problems is to teach students how to differentiate between problems that vary in severity, impact, and relative importance. Given this, problems can be described in three general forms: those that must be addressed immediately, those that should be addressed but the impact is not severe, and those that do not require immediate attention and can be set aside for the time being.

All of the problems you identify from the case should be identified in this section of your paper, with a description based on evidence explaining the problem variances. If the assignment asks you to conduct research to further support your assessment of the problems, include this in your explanation. Remember to cite those sources in a list of references. Use specific evidence from the case and apply appropriate concepts, theories, and models discussed in class or in relevant course readings to highlight and explain the key problems [or problem] that you believe must be solved immediately and describe the underlying symptoms and why they are so critical.

Alternative Solutions

This section is where you provide specific, realistic, and evidence-based solutions to the problems you have identified and make recommendations about how to alleviate the underlying symptomatic conditions impacting the organizational setting. For each solution, you must explain why it was chosen and provide clear evidence to support your reasoning. This can include, for example, course readings and class discussions as well as research resources, such as, books, journal articles, research reports, or government documents. In some cases, your professor may encourage you to include personal, anecdotal experiences as evidence to support why you chose a particular solution or set of solutions. Using anecdotal evidence helps promote reflective thinking about the process of determining what qualifies as a core problem and relevant solution .

Throughout this part of the paper, keep in mind the entire array of problems that must be addressed and describe in detail the solutions that might be implemented to resolve these problems.

Recommended Courses of Action

In some case analysis assignments, your professor may ask you to combine the alternative solutions section with your recommended courses of action. However, it is important to know the difference between the two. A solution refers to the answer to a problem. A course of action refers to a procedure or deliberate sequence of activities adopted to proactively confront a situation, often in the context of accomplishing a goal. In this context, proposed courses of action are based on your analysis of alternative solutions. Your description and justification for pursuing each course of action should represent the overall plan for implementing your recommendations.

For each course of action, you need to explain the rationale for your recommendation in a way that confronts challenges, explains risks, and anticipates any counter-arguments from stakeholders. Do this by considering the strengths and weaknesses of each course of action framed in relation to how the action is expected to resolve the core problems presented, the possible ways the action may affect remaining problems, and how the recommended action will be perceived by each stakeholder.

In addition, you should describe the criteria needed to measure how well the implementation of these actions is working and explain which individuals or groups are responsible for ensuring your recommendations are successful. In addition, always consider the law of unintended consequences. Outline difficulties that may arise in implementing each course of action and describe how implementing the proposed courses of action [either individually or collectively] may lead to new problems [both large and small].

Throughout this section, you must consider the costs and benefits of recommending your courses of action in relation to uncertainties or missing information and the negative consequences of success.

The conclusion should be brief and introspective. Unlike a research paper, the conclusion in a case analysis paper does not include a summary of key findings and their significance, a statement about how the study contributed to existing knowledge, or indicate opportunities for future research.

Begin by synthesizing the core problems presented in the case and the relevance of your recommended solutions. This can include an explanation of what you have learned about the case in the context of your answers to the questions provided by your professor. The conclusion is also where you link what you learned from analyzing the case with the course readings or class discussions. This can further demonstrate your understanding of the relationships between the practical case situation and the theoretical and abstract content of assigned readings and other course content.

Problems to Avoid

The literature on case analysis assignments often includes examples of difficulties students have with applying methods of critical analysis and effectively reporting the results of their assessment of the situation. A common reason cited by scholars is that the application of this type of teaching and learning method is limited to applied fields of social and behavioral sciences and, as a result, writing a case analysis paper can be unfamiliar to most students entering college.

After you have drafted your paper, proofread the narrative flow and revise any of these common errors:

• Unnecessary detail in the background section . The background section should highlight the essential elements of the case based on your analysis. Focus on summarizing the facts and highlighting the key factors that become relevant in the other sections of the paper by eliminating any unnecessary information.
• Analysis relies too much on opinion . Your analysis is interpretive, but the narrative must be connected clearly to evidence from the case and any models and theories discussed in class or in course readings. Any positions or arguments you make should be supported by evidence.
• Analysis does not focus on the most important elements of the case . Your paper should provide a thorough overview of the case. However, the analysis should focus on providing evidence about what you identify are the key events, stakeholders, issues, and problems. Emphasize what you identify as the most critical aspects of the case to be developed throughout your analysis. Be thorough but succinct.
• Writing is too descriptive . A paper with too much descriptive information detracts from your analysis of the complexities of the case situation. Questions about what happened, where, when, and by whom should only be included as essential information leading to your examination of questions related to why, how, and for what purpose.
• Inadequate definition of a core problem and associated symptoms . A common error found in case analysis papers is recommending a solution or course of action without adequately defining or demonstrating that you understand the problem. Make sure you have clearly described the problem and its impact and scope within the organizational setting. Ensure that you have adequately described the root causes w hen describing the symptoms of the problem.
• Recommendations lack specificity . Identify any use of vague statements and indeterminate terminology, such as, “A particular experience” or “a large increase to the budget.” These statements cannot be measured and, as a result, there is no way to evaluate their successful implementation. Provide specific data and use direct language in describing recommended actions.
• Unrealistic, exaggerated, or unattainable recommendations . Review your recommendations to ensure that they are based on the situational facts of the case. Your recommended solutions and courses of action must be based on realistic assumptions and fit within the constraints of the situation. Also note that the case scenario has already happened, therefore, any speculation or arguments about what could have occurred if the circumstances were different should be revised or eliminated.

Writing Tip

Ca se Study and Case Analysis Are Not the Same!

Confusion often exists between what it means to write a paper that uses a case study research design and writing a paper that analyzes a case; they are two different types of approaches to learning in the social and behavioral sciences. Professors as well as educational researchers contribute to this confusion because they often use the term "case study" when describing the subject of analysis for a case analysis paper. But you are not studying a case for the purpose of generating a comprehensive, multi-faceted understanding of a research problem. R ather, you are critically analyzing a specific scenario to argue logically for recommended solutions and courses of action that lead to optimal outcomes applicable to professional practice.

To avoid any confusion, here are twelve characteristics that delineate the differences between writing a paper using the case study research method and writing a case analysis paper:

• Case study is a method of in-depth research and rigorous inquiry ; case analysis is a reliable method of teaching and learning . A case study is a modality of research that investigates a phenomenon for the purpose of creating new knowledge, solving a problem, or testing a hypothesis using empirical evidence derived from the case being studied. Often, the results are used to generalize about a larger population or within a wider context. The writing adheres to the traditional standards of a scholarly research study. A case analysis is a pedagogical tool used to teach students how to reflect and think critically about a practical, real-life problem in an organizational setting.
• The researcher is responsible for identifying the case to study; a case analysis is assigned by your professor . As the researcher, you choose the case study to investigate in support of obtaining new knowledge and understanding about the research problem. The case in a case analysis assignment is almost always provided, and sometimes written, by your professor and either given to every student in class to analyze individually or to a small group of students, or students select a case to analyze from a predetermined list.
• A case study is indeterminate and boundless; a case analysis is predetermined and confined . A case study can be almost anything [see item 9 below] as long as it relates directly to examining the research problem. This relationship is the only limit to what a researcher can choose as the subject of their case study. The content of a case analysis is determined by your professor and its parameters are well-defined and limited to elucidating insights of practical value applied to practice.
• Case study is fact-based and describes actual events or situations; case analysis can be entirely fictional or adapted from an actual situation . The entire content of a case study must be grounded in reality to be a valid subject of investigation in an empirical research study. A case analysis only needs to set the stage for critically examining a situation in practice and, therefore, can be entirely fictional or adapted, all or in-part, from an actual situation.
• Research using a case study method must adhere to principles of intellectual honesty and academic integrity; a case analysis scenario can include misleading or false information . A case study paper must report research objectively and factually to ensure that any findings are understood to be logically correct and trustworthy. A case analysis scenario may include misleading or false information intended to deliberately distract from the central issues of the case. The purpose is to teach students how to sort through conflicting or useless information in order to come up with the preferred solution. Any use of misleading or false information in academic research is considered unethical.
• Case study is linked to a research problem; case analysis is linked to a practical situation or scenario . In the social sciences, the subject of an investigation is most often framed as a problem that must be researched in order to generate new knowledge leading to a solution. Case analysis narratives are grounded in real life scenarios for the purpose of examining the realities of decision-making behavior and processes within organizational settings. A case analysis assignments include a problem or set of problems to be analyzed. However, the goal is centered around the act of identifying and evaluating courses of action leading to best possible outcomes.
• The purpose of a case study is to create new knowledge through research; the purpose of a case analysis is to teach new understanding . Case studies are a choice of methodological design intended to create new knowledge about resolving a research problem. A case analysis is a mode of teaching and learning intended to create new understanding and an awareness of uncertainty applied to practice through acts of critical thinking and reflection.
• A case study seeks to identify the best possible solution to a research problem; case analysis can have an indeterminate set of solutions or outcomes . Your role in studying a case is to discover the most logical, evidence-based ways to address a research problem. A case analysis assignment rarely has a single correct answer because one of the goals is to force students to confront the real life dynamics of uncertainly, ambiguity, and missing or conflicting information within professional practice. Under these conditions, a perfect outcome or solution almost never exists.
• Case study is unbounded and relies on gathering external information; case analysis is a self-contained subject of analysis . The scope of a case study chosen as a method of research is bounded. However, the researcher is free to gather whatever information and data is necessary to investigate its relevance to understanding the research problem. For a case analysis assignment, your professor will often ask you to examine solutions or recommended courses of action based solely on facts and information from the case.
• Case study can be a person, place, object, issue, event, condition, or phenomenon; a case analysis is a carefully constructed synopsis of events, situations, and behaviors . The research problem dictates the type of case being studied and, therefore, the design can encompass almost anything tangible as long as it fulfills the objective of generating new knowledge and understanding. A case analysis is in the form of a narrative containing descriptions of facts, situations, processes, rules, and behaviors within a particular setting and under a specific set of circumstances.
• Case study can represent an open-ended subject of inquiry; a case analysis is a narrative about something that has happened in the past . A case study is not restricted by time and can encompass an event or issue with no temporal limit or end. For example, the current war in Ukraine can be used as a case study of how medical personnel help civilians during a large military conflict, even though circumstances around this event are still evolving. A case analysis can be used to elicit critical thinking about current or future situations in practice, but the case itself is a narrative about something finite and that has taken place in the past.
• Multiple case studies can be used in a research study; case analysis involves examining a single scenario . Case study research can use two or more cases to examine a problem, often for the purpose of conducting a comparative investigation intended to discover hidden relationships, document emerging trends, or determine variations among different examples. A case analysis assignment typically describes a stand-alone, self-contained situation and any comparisons among cases are conducted during in-class discussions and/or student presentations.

Case studies

Case studies are essential to qualitative research , offering a lens through which researchers can investigate complex phenomena within their real-life contexts. This chapter explores the concept, purpose, applications, examples, and types of case studies and provides guidance on how to conduct case study research effectively.

Whereas quantitative methods look at phenomena at scale, case study research looks at a concept or phenomenon in considerable detail. While analyzing a single case can help understand one perspective regarding the object of research inquiry, analyzing multiple cases can help obtain a more holistic sense of the topic or issue. Let's provide a basic definition of a case study, then explore its characteristics and role in the qualitative research process.

Definition of a case study

A case study in qualitative research is a strategy of inquiry that involves an in-depth investigation of a phenomenon within its real-world context. It provides researchers with the opportunity to acquire an in-depth understanding of intricate details that might not be as apparent or accessible through other methods of research. The specific case or cases being studied can be a single person, group, or organization – demarcating what constitutes a relevant case worth studying depends on the researcher and their research question .

Among qualitative research methods , a case study relies on multiple sources of evidence, such as documents, artifacts, interviews , or observations , to present a complete and nuanced understanding of the phenomenon under investigation. The objective is to illuminate the readers' understanding of the phenomenon beyond its abstract statistical or theoretical explanations.

Characteristics of case studies

Case studies typically possess a number of distinct characteristics that set them apart from other research methods. These characteristics include a focus on holistic description and explanation, flexibility in the design and data collection methods, reliance on multiple sources of evidence, and emphasis on the context in which the phenomenon occurs.

Furthermore, case studies can often involve a longitudinal examination of the case, meaning they study the case over a period of time. These characteristics allow case studies to yield comprehensive, in-depth, and richly contextualized insights about the phenomenon of interest.

The role of case studies in research

Case studies hold a unique position in the broader landscape of research methods aimed at theory development. They are instrumental when the primary research interest is to gain an intensive, detailed understanding of a phenomenon in its real-life context.

In addition, case studies can serve different purposes within research - they can be used for exploratory, descriptive, or explanatory purposes, depending on the research question and objectives. This flexibility and depth make case studies a valuable tool in the toolkit of qualitative researchers.

Remember, a well-conducted case study can offer a rich, insightful contribution to both academic and practical knowledge through theory development or theory verification, thus enhancing our understanding of complex phenomena in their real-world contexts.

What is the purpose of a case study?

Case study research aims for a more comprehensive understanding of phenomena, requiring various research methods to gather information for qualitative analysis . Ultimately, a case study can allow the researcher to gain insight into a particular object of inquiry and develop a theoretical framework relevant to the research inquiry.

Why use case studies in qualitative research?

Using case studies as a research strategy depends mainly on the nature of the research question and the researcher's access to the data.

Conducting case study research provides a level of detail and contextual richness that other research methods might not offer. They are beneficial when there's a need to understand complex social phenomena within their natural contexts.

The explanatory, exploratory, and descriptive roles of case studies

Case studies can take on various roles depending on the research objectives. They can be exploratory when the research aims to discover new phenomena or define new research questions; they are descriptive when the objective is to depict a phenomenon within its context in a detailed manner; and they can be explanatory if the goal is to understand specific relationships within the studied context. Thus, the versatility of case studies allows researchers to approach their topic from different angles, offering multiple ways to uncover and interpret the data .

The impact of case studies on knowledge development

Case studies play a significant role in knowledge development across various disciplines. Analysis of cases provides an avenue for researchers to explore phenomena within their context based on the collected data.

This can result in the production of rich, practical insights that can be instrumental in both theory-building and practice. Case studies allow researchers to delve into the intricacies and complexities of real-life situations, uncovering insights that might otherwise remain hidden.

Types of case studies

In qualitative research , a case study is not a one-size-fits-all approach. Depending on the nature of the research question and the specific objectives of the study, researchers might choose to use different types of case studies. These types differ in their focus, methodology, and the level of detail they provide about the phenomenon under investigation.

Understanding these types is crucial for selecting the most appropriate approach for your research project and effectively achieving your research goals. Let's briefly look at the main types of case studies.

Exploratory case studies

Exploratory case studies are typically conducted to develop a theory or framework around an understudied phenomenon. They can also serve as a precursor to a larger-scale research project. Exploratory case studies are useful when a researcher wants to identify the key issues or questions which can spur more extensive study or be used to develop propositions for further research. These case studies are characterized by flexibility, allowing researchers to explore various aspects of a phenomenon as they emerge, which can also form the foundation for subsequent studies.

Descriptive case studies

Descriptive case studies aim to provide a complete and accurate representation of a phenomenon or event within its context. These case studies are often based on an established theoretical framework, which guides how data is collected and analyzed. The researcher is concerned with describing the phenomenon in detail, as it occurs naturally, without trying to influence or manipulate it.

Explanatory case studies

Explanatory case studies are focused on explanation - they seek to clarify how or why certain phenomena occur. Often used in complex, real-life situations, they can be particularly valuable in clarifying causal relationships among concepts and understanding the interplay between different factors within a specific context.

Intrinsic, instrumental, and collective case studies

These three categories of case studies focus on the nature and purpose of the study. An intrinsic case study is conducted when a researcher has an inherent interest in the case itself. Instrumental case studies are employed when the case is used to provide insight into a particular issue or phenomenon. A collective case study, on the other hand, involves studying multiple cases simultaneously to investigate some general phenomena.

Each type of case study serves a different purpose and has its own strengths and challenges. The selection of the type should be guided by the research question and objectives, as well as the context and constraints of the research.

The flexibility, depth, and contextual richness offered by case studies make this approach an excellent research method for various fields of study. They enable researchers to investigate real-world phenomena within their specific contexts, capturing nuances that other research methods might miss. Across numerous fields, case studies provide valuable insights into complex issues.

Critical information systems research

Case studies provide a detailed understanding of the role and impact of information systems in different contexts. They offer a platform to explore how information systems are designed, implemented, and used and how they interact with various social, economic, and political factors. Case studies in this field often focus on examining the intricate relationship between technology, organizational processes, and user behavior, helping to uncover insights that can inform better system design and implementation.

Health research

Health research is another field where case studies are highly valuable. They offer a way to explore patient experiences, healthcare delivery processes, and the impact of various interventions in a real-world context.

Case studies can provide a deep understanding of a patient's journey, giving insights into the intricacies of disease progression, treatment effects, and the psychosocial aspects of health and illness.

Asthma research studies

Specifically within medical research, studies on asthma often employ case studies to explore the individual and environmental factors that influence asthma development, management, and outcomes. A case study can provide rich, detailed data about individual patients' experiences, from the triggers and symptoms they experience to the effectiveness of various management strategies. This can be crucial for developing patient-centered asthma care approaches.

Other fields

Apart from the fields mentioned, case studies are also extensively used in business and management research, education research, and political sciences, among many others. They provide an opportunity to delve into the intricacies of real-world situations, allowing for a comprehensive understanding of various phenomena.

Case studies, with their depth and contextual focus, offer unique insights across these varied fields. They allow researchers to illuminate the complexities of real-life situations, contributing to both theory and practice.

Understanding the key elements of case study design is crucial for conducting rigorous and impactful case study research. A well-structured design guides the researcher through the process, ensuring that the study is methodologically sound and its findings are reliable and valid. The main elements of case study design include the research question , propositions, units of analysis, and the logic linking the data to the propositions.

The research question is the foundation of any research study. A good research question guides the direction of the study and informs the selection of the case, the methods of collecting data, and the analysis techniques. A well-formulated research question in case study research is typically clear, focused, and complex enough to merit further detailed examination of the relevant case(s).

Propositions

Propositions, though not necessary in every case study, provide a direction by stating what we might expect to find in the data collected. They guide how data is collected and analyzed by helping researchers focus on specific aspects of the case. They are particularly important in explanatory case studies, which seek to understand the relationships among concepts within the studied phenomenon.

Units of analysis

The unit of analysis refers to the case, or the main entity or entities that are being analyzed in the study. In case study research, the unit of analysis can be an individual, a group, an organization, a decision, an event, or even a time period. It's crucial to clearly define the unit of analysis, as it shapes the qualitative data analysis process by allowing the researcher to analyze a particular case and synthesize analysis across multiple case studies to draw conclusions.

Argumentation

This refers to the inferential model that allows researchers to draw conclusions from the data. The researcher needs to ensure that there is a clear link between the data, the propositions (if any), and the conclusions drawn. This argumentation is what enables the researcher to make valid and credible inferences about the phenomenon under study.

Understanding and carefully considering these elements in the design phase of a case study can significantly enhance the quality of the research. It can help ensure that the study is methodologically sound and its findings contribute meaningful insights about the case.

Conducting a case study involves several steps, from defining the research question and selecting the case to collecting and analyzing data . This section outlines these key stages, providing a practical guide on how to conduct case study research.

Defining the research question

The first step in case study research is defining a clear, focused research question. This question should guide the entire research process, from case selection to analysis. It's crucial to ensure that the research question is suitable for a case study approach. Typically, such questions are exploratory or descriptive in nature and focus on understanding a phenomenon within its real-life context.

Selecting and defining the case

The selection of the case should be based on the research question and the objectives of the study. It involves choosing a unique example or a set of examples that provide rich, in-depth data about the phenomenon under investigation. After selecting the case, it's crucial to define it clearly, setting the boundaries of the case, including the time period and the specific context.

Previous research can help guide the case study design. When considering a case study, an example of a case could be taken from previous case study research and used to define cases in a new research inquiry. Considering recently published examples can help understand how to select and define cases effectively.

Developing a detailed case study protocol

A case study protocol outlines the procedures and general rules to be followed during the case study. This includes the data collection methods to be used, the sources of data, and the procedures for analysis. Having a detailed case study protocol ensures consistency and reliability in the study.

The protocol should also consider how to work with the people involved in the research context to grant the research team access to collecting data. As mentioned in previous sections of this guide, establishing rapport is an essential component of qualitative research as it shapes the overall potential for collecting and analyzing data.

Collecting data

Gathering data in case study research often involves multiple sources of evidence, including documents, archival records, interviews, observations, and physical artifacts. This allows for a comprehensive understanding of the case. The process for gathering data should be systematic and carefully documented to ensure the reliability and validity of the study.

Analyzing and interpreting data

The next step is analyzing the data. This involves organizing the data , categorizing it into themes or patterns , and interpreting these patterns to answer the research question. The analysis might also involve comparing the findings with prior research or theoretical propositions.

Writing the case study report

The final step is writing the case study report . This should provide a detailed description of the case, the data, the analysis process, and the findings. The report should be clear, organized, and carefully written to ensure that the reader can understand the case and the conclusions drawn from it.

Each of these steps is crucial in ensuring that the case study research is rigorous, reliable, and provides valuable insights about the case.

The type, depth, and quality of data in your study can significantly influence the validity and utility of the study. In case study research, data is usually collected from multiple sources to provide a comprehensive and nuanced understanding of the case. This section will outline the various methods of collecting data used in case study research and discuss considerations for ensuring the quality of the data.

Interviews are a common method of gathering data in case study research. They can provide rich, in-depth data about the perspectives, experiences, and interpretations of the individuals involved in the case. Interviews can be structured , semi-structured , or unstructured , depending on the research question and the degree of flexibility needed.

Observations

Observations involve the researcher observing the case in its natural setting, providing first-hand information about the case and its context. Observations can provide data that might not be revealed in interviews or documents, such as non-verbal cues or contextual information.

Documents and artifacts

Documents and archival records provide a valuable source of data in case study research. They can include reports, letters, memos, meeting minutes, email correspondence, and various public and private documents related to the case.

These records can provide historical context, corroborate evidence from other sources, and offer insights into the case that might not be apparent from interviews or observations.

Physical artifacts refer to any physical evidence related to the case, such as tools, products, or physical environments. These artifacts can provide tangible insights into the case, complementing the data gathered from other sources.

Ensuring the quality of data collection

Determining the quality of data in case study research requires careful planning and execution. It's crucial to ensure that the data is reliable, accurate, and relevant to the research question. This involves selecting appropriate methods of collecting data, properly training interviewers or observers, and systematically recording and storing the data. It also includes considering ethical issues related to collecting and handling data, such as obtaining informed consent and ensuring the privacy and confidentiality of the participants.

Data analysis

Analyzing case study research involves making sense of the rich, detailed data to answer the research question. This process can be challenging due to the volume and complexity of case study data. However, a systematic and rigorous approach to analysis can ensure that the findings are credible and meaningful. This section outlines the main steps and considerations in analyzing data in case study research.

Organizing the data

The first step in the analysis is organizing the data. This involves sorting the data into manageable sections, often according to the data source or the theme. This step can also involve transcribing interviews, digitizing physical artifacts, or organizing observational data.

Categorizing and coding the data

Once the data is organized, the next step is to categorize or code the data. This involves identifying common themes, patterns, or concepts in the data and assigning codes to relevant data segments. Coding can be done manually or with the help of software tools, and in either case, qualitative analysis software can greatly facilitate the entire coding process. Coding helps to reduce the data to a set of themes or categories that can be more easily analyzed.

Identifying patterns and themes

After coding the data, the researcher looks for patterns or themes in the coded data. This involves comparing and contrasting the codes and looking for relationships or patterns among them. The identified patterns and themes should help answer the research question.

Interpreting the data

Once patterns and themes have been identified, the next step is to interpret these findings. This involves explaining what the patterns or themes mean in the context of the research question and the case. This interpretation should be grounded in the data, but it can also involve drawing on theoretical concepts or prior research.

Verification of the data

The last step in the analysis is verification. This involves checking the accuracy and consistency of the analysis process and confirming that the findings are supported by the data. This can involve re-checking the original data, checking the consistency of codes, or seeking feedback from research participants or peers.

Like any research method , case study research has its strengths and limitations. Researchers must be aware of these, as they can influence the design, conduct, and interpretation of the study.

Understanding the strengths and limitations of case study research can also guide researchers in deciding whether this approach is suitable for their research question . This section outlines some of the key strengths and limitations of case study research.

Benefits include the following:

• Rich, detailed data: One of the main strengths of case study research is that it can generate rich, detailed data about the case. This can provide a deep understanding of the case and its context, which can be valuable in exploring complex phenomena.
• Flexibility: Case study research is flexible in terms of design , data collection , and analysis . A sufficient degree of flexibility allows the researcher to adapt the study according to the case and the emerging findings.
• Real-world context: Case study research involves studying the case in its real-world context, which can provide valuable insights into the interplay between the case and its context.
• Multiple sources of evidence: Case study research often involves collecting data from multiple sources , which can enhance the robustness and validity of the findings.

On the other hand, researchers should consider the following limitations:

• Generalizability: A common criticism of case study research is that its findings might not be generalizable to other cases due to the specificity and uniqueness of each case.
• Time and resource intensive: Case study research can be time and resource intensive due to the depth of the investigation and the amount of collected data.
• Complexity of analysis: The rich, detailed data generated in case study research can make analyzing the data challenging.
• Subjectivity: Given the nature of case study research, there may be a higher degree of subjectivity in interpreting the data , so researchers need to reflect on this and transparently convey to audiences how the research was conducted.

Being aware of these strengths and limitations can help researchers design and conduct case study research effectively and interpret and report the findings appropriately.

• Case Teaching
• Student Engagement

J ust as actors, athletes, and musicians spend thousands of hours practicing their craft, business students benefit from practicing their critical-thinking and decision-making skills. Students, however, often have limited exposure to real-world problem-solving scenarios; they need more opportunities to practice tackling tough business problems and deciding on—and executing—the best solutions.

To ensure students have ample opportunity to develop these critical-thinking and decision-making skills, we believe business faculty should shift from teaching mostly principles and ideas to mostly applications and practices. And in doing so, they should emphasize the case method, which simulates real-world management challenges and opportunities for students.

To help educators facilitate this shift and help students get the most out of case-based learning, we have developed a framework for analyzing cases. We call it PACADI (Problem, Alternatives, Criteria, Analysis, Decision, Implementation); it can improve learning outcomes by helping students better solve and analyze business problems, make decisions, and develop and implement strategy. Here, we’ll explain why we developed this framework, how it works, and what makes it an effective learning tool.

The Case for Cases: Helping Students Think Critically

Business students must develop critical-thinking and analytical skills, which are essential to their ability to make good decisions in functional areas such as marketing, finance, operations, and information technology, as well as to understand the relationships among these functions. For example, the decisions a marketing manager must make include strategic planning (segments, products, and channels); execution (digital messaging, media, branding, budgets, and pricing); and operations (integrated communications and technologies), as well as how to implement decisions across functional areas.

Faculty can use many types of cases to help students develop these skills. These include the prototypical “paper cases”; live cases , which feature guest lecturers such as entrepreneurs or corporate leaders and on-site visits; and multimedia cases , which immerse students into real situations. Most cases feature an explicit or implicit decision that a protagonist—whether it is an individual, a group, or an organization—must make.

For students new to learning by the case method—and even for those with case experience—some common issues can emerge; these issues can sometimes be a barrier for educators looking to ensure the best possible outcomes in their case classrooms. Unsure of how to dig into case analysis on their own, students may turn to the internet or rely on former students for “answers” to assigned cases. Or, when assigned to provide answers to assignment questions in teams, students might take a divide-and-conquer approach but not take the time to regroup and provide answers that are consistent with one other.

To help address these issues, which we commonly experienced in our classes, we wanted to provide our students with a more structured approach for how they analyze cases—and to really think about making decisions from the protagonists’ point of view. We developed the PACADI framework to address this need.

PACADI: A Six-Step Decision-Making Approach

The PACADI framework is a six-step decision-making approach that can be used in lieu of traditional end-of-case questions. It offers a structured, integrated, and iterative process that requires students to analyze case information, apply business concepts to derive valuable insights, and develop recommendations based on these insights.

Prior to beginning a PACADI assessment, which we’ll outline here, students should first prepare a two-paragraph summary—a situation analysis—that highlights the key case facts. Then, we task students with providing a five-page PACADI case analysis (excluding appendices) based on the following six steps.

Step 1: Problem definition. What is the major challenge, problem, opportunity, or decision that has to be made? If there is more than one problem, choose the most important one. Often when solving the key problem, other issues will surface and be addressed. The problem statement may be framed as a question; for example, How can brand X improve market share among millennials in Canada? Usually the problem statement has to be re-written several times during the analysis of a case as students peel back the layers of symptoms or causation.

Step 2: Alternatives. Identify in detail the strategic alternatives to address the problem; three to five options generally work best. Alternatives should be mutually exclusive, realistic, creative, and feasible given the constraints of the situation. Doing nothing or delaying the decision to a later date are not considered acceptable alternatives.

Step 3: Criteria. What are the key decision criteria that will guide decision-making? In a marketing course, for example, these may include relevant marketing criteria such as segmentation, positioning, advertising and sales, distribution, and pricing. Financial criteria useful in evaluating the alternatives should be included—for example, income statement variables, customer lifetime value, payback, etc. Students must discuss their rationale for selecting the decision criteria and the weights and importance for each factor.

Step 4: Analysis. Provide an in-depth analysis of each alternative based on the criteria chosen in step three. Decision tables using criteria as columns and alternatives as rows can be helpful. The pros and cons of the various choices as well as the short- and long-term implications of each may be evaluated. Best, worst, and most likely scenarios can also be insightful.

Step 5: Decision. Students propose their solution to the problem. This decision is justified based on an in-depth analysis. Explain why the recommendation made is the best fit for the criteria.

Step 6: Implementation plan. Sound business decisions may fail due to poor execution. To enhance the likeliness of a successful project outcome, students describe the key steps (activities) to implement the recommendation, timetable, projected costs, expected competitive reaction, success metrics, and risks in the plan.

“Students note that using the PACADI framework yields ‘aha moments’—they learned something surprising in the case that led them to think differently about the problem and their proposed solution.”

PACADI’s Benefits: Meaningfully and Thoughtfully Applying Business Concepts

The PACADI framework covers all of the major elements of business decision-making, including implementation, which is often overlooked. By stepping through the whole framework, students apply relevant business concepts and solve management problems via a systematic, comprehensive approach; they’re far less likely to surface piecemeal responses.

As students explore each part of the framework, they may realize that they need to make changes to a previous step. For instance, when working on implementation, students may realize that the alternative they selected cannot be executed or will not be profitable, and thus need to rethink their decision. Or, they may discover that the criteria need to be revised since the list of decision factors they identified is incomplete (for example, the factors may explain key marketing concerns but fail to address relevant financial considerations) or is unrealistic (for example, they suggest a 25 percent increase in revenues without proposing an increased promotional budget).

In addition, the PACADI framework can be used alongside quantitative assignments, in-class exercises, and business and management simulations. The structured, multi-step decision framework encourages careful and sequential analysis to solve business problems. Incorporating PACADI as an overarching decision-making method across different projects will ultimately help students achieve desired learning outcomes. As a practical “beyond-the-classroom” tool, the PACADI framework is not a contrived course assignment; it reflects the decision-making approach that managers, executives, and entrepreneurs exercise daily. Case analysis introduces students to the real-world process of making business decisions quickly and correctly, often with limited information. This framework supplies an organized and disciplined process that students can readily defend in writing and in class discussions.

PACADI in Action: An Example

Here’s an example of how students used the PACADI framework for a recent case analysis on CVS, a large North American drugstore chain.

Results of Using the PACADI Framework

When faculty members at our respective institutions at Nova Southeastern University (NSU) and the University of North Carolina Wilmington have used the PACADI framework, our classes have been more structured and engaging. Students vigorously debate each element of their decision and note that this framework yields an “aha moment”—they learned something surprising in the case that led them to think differently about the problem and their proposed solution.

These lively discussions enhance individual and collective learning. As one external metric of this improvement, we have observed a 2.5 percent increase in student case grade performance at NSU since this framework was introduced.

Tips to Get Started

The PACADI approach works well in in-person, online, and hybrid courses. This is particularly important as more universities have moved to remote learning options. Because students have varied educational and cultural backgrounds, work experience, and familiarity with case analysis, we recommend that faculty members have students work on their first case using this new framework in small teams (two or three students). Additional analyses should then be solo efforts.

To use PACADI effectively in your classroom, we suggest the following:

Advise your students that your course will stress critical thinking and decision-making skills, not just course concepts and theory.

Use a varied mix of case studies. As marketing professors, we often address consumer and business markets; goods, services, and digital commerce; domestic and global business; and small and large companies in a single MBA course.

As a starting point, provide a short explanation (about 20 to 30 minutes) of the PACADI framework with a focus on the conceptual elements. You can deliver this face to face or through videoconferencing.

Give students an opportunity to practice the case analysis methodology via an ungraded sample case study. Designate groups of five to seven students to discuss the case and the six steps in breakout sessions (in class or via Zoom).

Ensure case analyses are weighted heavily as a grading component. We suggest 30–50 percent of the overall course grade.

Once cases are graded, debrief with the class on what they did right and areas needing improvement (30- to 40-minute in-person or Zoom session).

Encourage faculty teams that teach common courses to build appropriate instructional materials, grading rubrics, videos, sample cases, and teaching notes.

When selecting case studies, we have found that the best ones for PACADI analyses are about 15 pages long and revolve around a focal management decision. This length provides adequate depth yet is not protracted. Some of our tested and favorite marketing cases include Brand W , Hubspot , Kraft Foods Canada , TRSB(A) , and Whiskey & Cheddar .

Answered By: Coleen Neary Last Updated: Jun 02, 2023     Views: 265999

A case study analysis requires you to investigate a business problem, examine the alternative solutions, and propose the most effective solution using supporting evidenc e.

Before you begin writing, follow these guidelines to help you prepare and understand the case study:

• Take notes, highlight relevant facts, and underline key problems.
• Identify two to five key problems
• Why do they exist?
• How do they impact the organization?
• Who is responsible for them?
• Review course readings, discussions, outside research, and your experience.
• Consider strong supporting evidence, pros, and cons: is this solution realistic?

Once you have gathered the necessary information, a draft of your analysis should include these sections:

• Identify the key problems and issues in the case study.
• Formulate and include a thesis statement, summarizing the outcome of your analysis in 1–2 sentences.
• Set the scene: background information, relevant facts, and the most important issues.
• Demonstrate that you have researched the problems in this case study.
• Outline possible alternatives (not necessarily all of them)
• Explain why alternatives were rejected
• Constraints/reasons
• Why are alternatives not possible at this time?
• Provide one specific and realistic solution
• Explain why this solution was chosen
• Support this solution with solid evidence
• Concepts from class (text readings, discussions, lectures)
• Outside research
• Personal experience (anecdotes)
• Determine and discuss specific strategies for accomplishing the proposed solution.
• If applicable, recommend further action to resolve some of the issues
• What should be done and who should do it?

After you have composed the first draft of your case study analysis, read through it to check for any gaps or inconsistencies in content or structure: Is your thesis statement clear and direct? Have you provided solid evidence? Is any component from the analysis missing?

Alternative Courses of Action in Case Study: Examples and How To Write

The ultimate goal of creating a case study is to develop a feasible action that can solve the problem it raised.

One way to achieve this is by enumerating all the possible solutions for your case study’s subject. The portion of the case study where you perform this is called ACA or Alternative Courses of Action.

Are you struggling with writing your case study’s ACA?  Do not worry; we have provided you with the most detailed guide on writing the Alternative Courses of Action (ACA) of a case study.

Table of Contents

What are alternative courses of action (aca) in a case study.

Alternative Courses of Action (ACA) are the possible actions a firm or organization can implement to address the problem indicated in the case study. These are suggested actions that a firm can consider to arrive at the most feasible and effective solution to the problem. 

This portion doesn’t provide the actual and optimal solution yet. Instead, it contains proposed alternatives that will still undergo an evaluation of their respective advantages and disadvantages to help you come up with the best solution. 

The ACA you will offer and indicate will be based on your case study’s SWOT analysis in the “ Areas of Consideration ” portion. Thus, a SWOT analysis is performed first before writing the ACA.

What Is the Importance of Alternative Courses of Action (ACA) in a Case Study?

Given the financial, logistical, and operational limitations, developing solutions that the firm can perform can be challenging. By enumerating and evaluating the ACA of your case study, you can filter out the alternatives that can be a potential solution to the problem, given the business’s constraints 1 . This makes your proposed solutions feasible and more meaningful.

How To Write Alternative Courses of Action in Case Study

Here are the steps on how to write the Alternative Courses of Action for your case study:

1. Analyze the Results of Your SWOT Analysis

Using the SWOT analysis, consider how the firm can use its strengths and opportunities to address its weaknesses, mitigate threats, and eventually solve the case study’s problem. 

Suppose that the case study’s problem is declining monthly sales, and the SWOT analysis showed the following:

• Strength : Creative marketing team 
• Opportunity : Increasing trend of using social media to promote products

Then, you may include an ACA about developing the digital marketing arm of the firm to attract more customers and boost monthly sales. This can also address one of the possible threats the firm faces, which is increasing direct marketing costs.

2. Write Your Proposed Solutions/Alternative Courses of Action (ACA) for Your Case Study’s Problem

Once you have reviewed your SWOT analysis and come up with possible solutions, it’s time to write them formally in your manuscript. Each solution does not have to be too detailed and wordy. State the specific action that the firm must perform concisely.

Going back to our previous example in Step 1, here is one of the possible ACA that can be included:

ACA #1: Utilize digital platforms such as web pages and social media sites as an alternative marketing platform to reach a wider potential customer base. Digital marketing, together with the traditional direct marketing strategy currently employed, maximizes the business’ market presence, attracting more customers, and potentially driving revenues upward.

In our example above, there is a clear statement of the firm’s action: to use web pages and social media sites to reach more potential customers and increase market presence. Notice how the ACA above provides only an overview of “what to do” and not a complete elaboration on “how to do it.” 

3. Identify the Advantages and Disadvantages of Each ACA You Have Proposed

After specifying the ACA, you must evaluate them by stating their respective advantages (pros) and disadvantages (cons). In other words, you must state how your ACA favors the firm (advantages) and its downsides and limitations (disadvantages).

Again, your evaluation does not have to be too detailed but make sure that it is relevant to the ACA that it pertains to. 

Let’s return to the ACA we developed from step 2, utilizing digital platforms (e.g., social media sites) to reach more potential customers. What do you think will be the pros and cons of this ACA?

Let’s start with its potential benefits (advantages). Using digital platforms is cheaper than using print ads or direct marketing. So, this will save some funds for the firm. In short, it is cost-effective. 

Second, digital platforms offer analytical tools to measure your ads’ reach, making it easier to evaluate people’s perceptions of your offering. 

Third, using social media sites makes communicating with any potential customer easier. You can quickly respond to their queries, especially if they are interested in your product. 

Lastly, you can reach as many types of people as possible by taking advantage of the internet algorithm.

Now, let us consider its disadvantages 2 . First, using digital marketing takes time and effort to learn, and you must be able to adapt quickly to the changes in trends and new strategies to keep up with the competition. 

Second, you must deal with the increasing market competition, as many businesses already use digital platforms. 

Third, you have to deal with negative feedback from your customers that are visible to the public and may affect their perception of your brand.

After pondering over the pros and cons of your ACA, it’s time to write them concisely in your manuscript. You can present it in two ways: by tabulating it or by simply listing them.

Example in Table Form:

Examples of Alternative Courses of Action (ACA) in a Case Study

Case Study Problem: Xenon Pastries faces a problem handling larger orders as Christmas Day approaches. With an estimated 15% increase in customer demand, this is the most significant increase in their daily orders since 2012. The management aims to maximize profit opportunities given the rise in customer demand. 

ACA #1: Hire part-time workers to increase staff numbers and meet the overwhelming seasonal increase in customer orders. Currently, Xenon Pastries has a total of 9 workers who are responsible for the accommodation of orders, preparation, and delivery of products, and addressing customers’ inquiries and complaints. Hiring 2 – 3 part-time workers can increase productivity and meet the daily order volume.

• Do not require too much effort to implement since hiring announcements only require signages or social media postings
• High certainty of finding potential workers due to the high unemployment rate
• Improve overall productivity of the business and the well-being of other workers since their workload will be lessened

Disadvantages

• Increase in operating expense in the form of wages to the new workers
• Managing more employees and monitoring their performance can be challenging
• New workers might find it challenging to adapt essential skills required in the operation of the business

ACA #2: Increase the prices of Xenon pastries’ products to increase revenues . This option can maximize Xenon Pastries’ profit even if not all customers’ orders are accommodated. 

• Cost-effective
• Easy to implement since it only requires changing the price tags of the products
• If customers’ desire to buy the products does not change, the price increase will certainly increase the business’ revenue
• Some customers might be discouraged from buying because of an increase in prices
• There’s a possibility that the increase in the price of the products will make it more expensive relative to competitors’ products

Case Study Problem: Delta Motors has been manufacturing motorcycles for ten years. Recently, the business suffered a gradual shrink in its quarterly revenues due to the increasing popularity of traditional and newly-developed electric bikes. Delta Motors seeks a long-term strategy to attract potential customers to bounce back sales.  

ACA #1: Develop a “regular installment payment” scheme to attract customers who wish to purchase motorcycles but have insufficient lump-sum money to acquire one.  This payment scheme allows customers to pay an initial deposit and the remaining amount through smaller monthly payments.

• Enticing for middle to low-income individuals who comprise a large chunk of the population
• Requires low initial capital to implement 
• Provides a new source of monthly income streams that can benefit the financial standing of the company
• Risk of default or delays in installment payments
• Requires additional human resources to manage and collect installment payments
• The payment scheme requires time to gain returns due to the periodic flow of funds
• Requires a careful creation of guidelines and terms and conditions to ensure smooth facilitation of the installment payment scheme

ACA #2: Introduce new motorcycle models that can entice different types of customers. These models will feature popular designs and more efficient engines.

• This may capture the public’s interest in Delta Motors, which can lead to an increase in the number of potential customers and earning opportunities
• Enables the business to keep up with the intense market competition by providing something “fresh” to the public
• Provides more alternatives for those who already support Delta Motors, strengthening their loyalty to the brand
• Conceptualization of a new model takes a lot of brainstorming to test its feasibility and effectiveness
• Requires sufficient funds to sustain the investment for the development of a new model
• It requires effective marketing strategies to promote the new model to the public

Tips and Warnings

• Do not include in this portion your case study’s conclusion . Think of ACA as a list of possible ways to address the problem. In other words, you suggest the possible alternatives to be selected here. The “ Recommendation ” portion of your case study is where you pick the most appropriate way to solve the problem.
• Use statistical data to support the advantages and disadvantages of each ACA. Although this is optional, presenting numerical data makes your analysis more concrete and factual than just stating them descriptively. 
• Do not fall into the “meat sandwich” trap. This happens when you intently make some of the alternatives less desirable so that your preferred choice stands out. This can be done by refusing to elaborate on their benefits or excessively concentrating on their disadvantages. Make sure that each ACA has potential and can be implemented realistically.

Frequently Asked Questions

1. how many alternative courses of action (aca) can a case study have.

Sometimes your instructor or teacher will tell you the required number of ACA that must be included in your case study . However, there’s no “standard” limit to how many ACA you can indicate.

2. What is the difference between Alternative Courses of Action (ACA) and Recommendations?

As mentioned earlier, the case study’s ACA aims to enumerate all possible solutions to the problem. It is not the stage where you state the “final” action you deem most appropriate to address the issue. The case study portion where you explicitly mention your “best” alternative is called the “Recommendation.” 

To help you understand the point above, let’s return to our Delta Motors example. In our previous section, we have provided two ACA that can solve the problem, namely (1) developing a regular installment payment plan and (2) introducing a new motorcycle model. 

Suppose that upon careful analysis and evaluation of these ACA, you came up with ACA #2 as the more fitting solution to the problem. When you write your case study’s recommendation, you must indicate the ACA you chose and your reasons for selecting it. 

Here’s an example of the Recommendation of the case study:

Recommendation

Introducing new motorcycle models that feature popular designs and more efficient engines to entice different types of customers is the most promising alternative course of action that Delta Motors can implement to bounce back its quarterly revenues and keep up with the competitive market. This creates a strong impression on the public of the company’s dedication to promoting high-quality motorcycles that can withstand changes in consumer preferences and market trends. Furthermore, this action proves that the company is continuously evolving to offer a variety of alternative models to suit everyone’s tastes. With proper promotion, these models can rekindle the company’s popularity in the automotive and motorcycle industry.

What Is Alternative Analysis in Project Management?

There’s more than one way to skin a cat. That is to say—you can reach the same outcome through different means. To discover those means, you can use an alternative analysis. An alternative analysis is how project managers choose how they’re going to approach a project.

There are always options, and knowing which is the best one for your project takes time, research and an understanding of possible scenarios. An analysis of alternatives is required, and today’s blog will guide you through the tools and methods you should use to get the data you need.

What is Alternative Analysis?

An alternative analysis is the evaluation of the various routes you can pursue to achieve the goal of a project or a particular project management objective. It looks beyond the status quo to compare different ways of getting work done.

These factors can be operational, such as cost, risk and effectiveness, as well as the potential shortfalls of those operational factors. To perform an alternative analysis, you use tools such as life-cycle costing, sensitivity analysis, cash flow analysis and cost-benefit analysis .

Analysis of alternatives, also called AOA, is part of the decision-making process when looking at existing portfolios, programs and projects or while initiating a new project. This decision-making process helps you find cost-effective actions and avoid unnecessary effort duplication. Using AOA will help reduce the risk of project failure.

When Should Alternative Analysis Be Used in Project Management?

Alternative analysis is used whenever a solution is needed. When decision-makers are in the decision-making process, they want to know the best course for moving forward. An alternative analysis will show them the way.

An AOA is typically done at the initiation of a project  but is also used throughout the life cycle of the project. It’s one way to determine if the decision-making process is sound. Making updates throughout the process will refine the solution and reaffirm the assessment criteria.

However, an AOA is not something that’s simple to do. Analysis is often time-consuming. Because of the time and labor involved in an AOA, it’s more likely that you will apply it to portfolios or programs. These portfolios or programs are more of an ongoing concern than a single project, and managers are constantly on the lookout for ways to import the cost-effectiveness of the work.

Whatever way you use alternative analysis, you’ll need project management software to evaluate and choose the best course of action from a variety of options. ProjectManager delivers insightful real-time data to help in the analytic comparison. Real-time dashboards capture data for projects and automatically calculate that information into easy-to-read graphs and charts. Try ProjectManager today for free!

Benefits of Analysis of alternatives (AOA)

Using an analysis of alternatives (AOA) will help the project, portfolio and program managers identify, understand and evaluate the alternatives open to them when managing a project. It will also help them to select the best course of action as it concerns project costs and risks.

By looking at alternatives, decision-makers have more data to make an informed choice with. Being able to identify, define and understand a problem is the best way to solve it, and is essential to any worthwhile analysis.

When decision-makers have many alternatives to choose from, they have more power to control the outcome. But the data must be good. Avoiding prejudices, such as paying more attention to information that is easy to access, is important as well.

How to Execute an Alternative Analysis

An alternative analysis provides a framework to look at your process and seek out improvements that are of the greatest advantage to you. Follow these steps to help you determine which of these routes would be most advantageous.

1. Make a Plan

The first thing to do is make a plan . This means defining the various decisions that you can make to meet your objective and achieve operational effectiveness. You’ll want to include stakeholders, but also define the timing, effort or costs involved. There will need to be a study team assembled and a study plan to direct their activities.

2. Organize the Analytic Framework

The next step is to define the analysis problem statement, the context of the problem, scope and a framework for alternative comparisons. This includes the comparison criteria you’ll use. Frame the analysis with the ground rules you’ll use, including any assumptions you might have. Before and during the study, you’ll want to access the data needs, collection and sources used.

3. Identify and Define Alternatives

Now you identify the various alternative routes you can take from the data sources. There will be many, but be sure to keep one as the status quo. These alternatives will address the problem you stated in your plan within the context and scope you’ve already defined. The alternatives you evaluate must come out of thorough research, vetting and filtering before you can begin the decision-making process.

4. Assess the Alternatives

Look over each of the alternatives you’ve come up with. Evaluate them against your established criteria, such as cost, risk, life cycle cost-effectiveness, benefits and likelihood analysis. You’ll also need to conduct a sensitivity analysis, which is a financial model that looks at a target variable and how it is impacted by changes from input variables.

5. Compare the Alternatives

Here, you’ll weigh the pros and cons of the various alternatives you’ve identified. Determine what the merits of each are, as shown by the analysis you’ve made.

6. Report the Results

Finally, you’ll want to document the results of the AOA to show the life cycle cost that supports the alternative or status quo you chose, and how that will support the project decision-makers and/or stakeholder needs.

Alternative Analysis Tips

When managing a project, the alternative analysis should be part of your decision-making. It lets you to find the best way forward. To do this, you’ll need to create a study plan. It will act as a roadmap for how your analysis should proceed, and explain who is responsible for what.

You can’t do an alternative analysis without first devoting the time and resources needed. You need to give yourself enough time to look at the alternatives and determine the risks involved with each.

Be sure to always have a baseline of your status quo in order to have something to compare your alternatives against. It might also prove that the status quo is the best approach. Often collecting baseline data is time-consuming, so make sure you have scheduled enough time and resources to do it.

Manage Stakeholders

It’s also important to understand your stakeholders and their needs and manage their expectations. This will inform the scope and execution of your analysis.

Stakeholders will inform your comparison criteria, too. Just as knowing your stakeholders is important, so is assembling an appropriate team with the right skills and experience.

Be open to many perspectives and use the appropriate methods, tools and data to support the decision-making process. The data must work with the methodology used, or you’ll have bad data in and bad data out.

Case studies are in-depth investigations of a person, group, event, or community. Typically, data is gathered from various sources using several methods (e.g., observations & interviews).

The case study research method originated in clinical medicine (the case history, i.e., the patient’s personal history). In psychology, case studies are often confined to the study of a particular individual.

The information is mainly biographical and relates to events in the individual’s past (i.e., retrospective), as well as to significant events that are currently occurring in his or her everyday life.

The case study is not a research method, but researchers select methods of data collection and analysis that will generate material suitable for case studies.

Freud (1909a, 1909b) conducted very detailed investigations into the private lives of his patients in an attempt to both understand and help them overcome their illnesses.

This makes it clear that the case study is a method that should only be used by a psychologist, therapist, or psychiatrist, i.e., someone with a professional qualification.

There is an ethical issue of competence. Only someone qualified to diagnose and treat a person can conduct a formal case study relating to atypical (i.e., abnormal) behavior or atypical development.

 Famous Case Studies

• Anna O – One of the most famous case studies, documenting psychoanalyst Josef Breuer’s treatment of “Anna O” (real name Bertha Pappenheim) for hysteria in the late 1800s using early psychoanalytic theory.
• Little Hans – A child psychoanalysis case study published by Sigmund Freud in 1909 analyzing his five-year-old patient Herbert Graf’s house phobia as related to the Oedipus complex.
• Bruce/Brenda – Gender identity case of the boy (Bruce) whose botched circumcision led psychologist John Money to advise gender reassignment and raise him as a girl (Brenda) in the 1960s.
• Genie Wiley – Linguistics/psychological development case of the victim of extreme isolation abuse who was studied in 1970s California for effects of early language deprivation on acquiring speech later in life.
• Phineas Gage – One of the most famous neuropsychology case studies analyzes personality changes in railroad worker Phineas Gage after an 1848 brain injury involving a tamping iron piercing his skull.

Clinical Case Studies

• Studying the effectiveness of psychotherapy approaches with an individual patient
• Assessing and treating mental illnesses like depression, anxiety disorders, PTSD
• Neuropsychological cases investigating brain injuries or disorders

Child Psychology Case Studies

• Studying psychological development from birth through adolescence
• Cases of learning disabilities, autism spectrum disorders, ADHD
• Effects of trauma, abuse, deprivation on development

Types of Case Studies

• Explanatory case studies : Used to explore causation in order to find underlying principles. Helpful for doing qualitative analysis to explain presumed causal links.
• Exploratory case studies : Used to explore situations where an intervention being evaluated has no clear set of outcomes. It helps define questions and hypotheses for future research.
• Descriptive case studies : Describe an intervention or phenomenon and the real-life context in which it occurred. It is helpful for illustrating certain topics within an evaluation.
• Multiple-case studies : Used to explore differences between cases and replicate findings across cases. Helpful for comparing and contrasting specific cases.
• Intrinsic : Used to gain a better understanding of a particular case. Helpful for capturing the complexity of a single case.
• Collective : Used to explore a general phenomenon using multiple case studies. Helpful for jointly studying a group of cases in order to inquire into the phenomenon.

Where Do You Find Data for a Case Study?

There are several places to find data for a case study. The key is to gather data from multiple sources to get a complete picture of the case and corroborate facts or findings through triangulation of evidence. Most of this information is likely qualitative (i.e., verbal description rather than measurement), but the psychologist might also collect numerical data.

1. Primary sources

• Interviews – Interviewing key people related to the case to get their perspectives and insights. The interview is an extremely effective procedure for obtaining information about an individual, and it may be used to collect comments from the person’s friends, parents, employer, workmates, and others who have a good knowledge of the person, as well as to obtain facts from the person him or herself.
• Observations – Observing behaviors, interactions, processes, etc., related to the case as they unfold in real-time.
• Documents & Records – Reviewing private documents, diaries, public records, correspondence, meeting minutes, etc., relevant to the case.

2. Secondary sources

• News/Media – News coverage of events related to the case study.
• Academic articles – Journal articles, dissertations etc. that discuss the case.
• Government reports – Official data and records related to the case context.
• Books/films – Books, documentaries or films discussing the case.

3. Archival records

Searching historical archives, museum collections and databases to find relevant documents, visual/audio records related to the case history and context.

Public archives like newspapers, organizational records, photographic collections could all include potentially relevant pieces of information to shed light on attitudes, cultural perspectives, common practices and historical contexts related to psychology.

4. Organizational records

Organizational records offer the advantage of often having large datasets collected over time that can reveal or confirm psychological insights.

Of course, privacy and ethical concerns regarding confidential data must be navigated carefully.

However, with proper protocols, organizational records can provide invaluable context and empirical depth to qualitative case studies exploring the intersection of psychology and organizations.

• Organizational/industrial psychology research : Organizational records like employee surveys, turnover/retention data, policies, incident reports etc. may provide insight into topics like job satisfaction, workplace culture and dynamics, leadership issues, employee behaviors etc.
• Clinical psychology : Therapists/hospitals may grant access to anonymized medical records to study aspects like assessments, diagnoses, treatment plans etc. This could shed light on clinical practices.
• School psychology : Studies could utilize anonymized student records like test scores, grades, disciplinary issues, and counseling referrals to study child development, learning barriers, effectiveness of support programs, and more.

How do I Write a Case Study in Psychology?

Follow specified case study guidelines provided by a journal or your psychology tutor. General components of clinical case studies include: background, symptoms, assessments, diagnosis, treatment, and outcomes. Interpreting the information means the researcher decides what to include or leave out. A good case study should always clarify which information is the factual description and which is an inference or the researcher’s opinion.

1. Introduction

• Provide background on the case context and why it is of interest, presenting background information like demographics, relevant history, and presenting problem.
• Compare briefly to similar published cases if applicable. Clearly state the focus/importance of the case.

2. Case Presentation

• Describe the presenting problem in detail, including symptoms, duration,and impact on daily life.
• Include client demographics like age and gender, information about social relationships, and mental health history.
• Describe all physical, emotional, and/or sensory symptoms reported by the client.
• Use patient quotes to describe the initial complaint verbatim. Follow with full-sentence summaries of relevant history details gathered, including key components that led to a working diagnosis.
• Summarize clinical exam results, namely orthopedic/neurological tests, imaging, lab tests, etc. Note actual results rather than subjective conclusions. Provide images if clearly reproducible/anonymized.
• Clearly state the working diagnosis or clinical impression before transitioning to management.

3. Management and Outcome

• Indicate the total duration of care and number of treatments given over what timeframe. Use specific names/descriptions for any therapies/interventions applied.
• Present the results of the intervention,including any quantitative or qualitative data collected.
• For outcomes, utilize visual analog scales for pain, medication usage logs, etc., if possible. Include patient self-reports of improvement/worsening of symptoms. Note the reason for discharge/end of care.

4. Discussion

• Analyze the case, exploring contributing factors, limitations of the study, and connections to existing research.
• Analyze the effectiveness of the intervention,considering factors like participant adherence, limitations of the study, and potential alternative explanations for the results.
• Identify any questions raised in the case analysis and relate insights to established theories and current research if applicable. Avoid definitive claims about physiological explanations.
• Offer clinical implications, and suggest future research directions.

5. Additional Items

• Thank specific assistants for writing support only. No patient acknowledgments.
• References should directly support any key claims or quotes included.
• Use tables/figures/images only if substantially informative. Include permissions and legends/explanatory notes.
• Provides detailed (rich qualitative) information.
• Provides insight for further research.
• Permitting investigation of otherwise impractical (or unethical) situations.

Case studies allow a researcher to investigate a topic in far more detail than might be possible if they were trying to deal with a large number of research participants (nomothetic approach) with the aim of ‘averaging’.

Because of their in-depth, multi-sided approach, case studies often shed light on aspects of human thinking and behavior that would be unethical or impractical to study in other ways.

Research that only looks into the measurable aspects of human behavior is not likely to give us insights into the subjective dimension of experience, which is important to psychoanalytic and humanistic psychologists.

Case studies are often used in exploratory research. They can help us generate new ideas (that might be tested by other methods). They are an important way of illustrating theories and can help show how different aspects of a person’s life are related to each other.

The method is, therefore, important for psychologists who adopt a holistic point of view (i.e., humanistic psychologists ).

Limitations

• Lacking scientific rigor and providing little basis for generalization of results to the wider population.
• Researchers’ own subjective feelings may influence the case study (researcher bias).
• Difficult to replicate.
• Time-consuming and expensive.
• The volume of data, together with the time restrictions in place, impacted the depth of analysis that was possible within the available resources.

Because a case study deals with only one person/event/group, we can never be sure if the case study investigated is representative of the wider body of “similar” instances. This means the conclusions drawn from a particular case may not be transferable to other settings.

Because case studies are based on the analysis of qualitative (i.e., descriptive) data , a lot depends on the psychologist’s interpretation of the information she has acquired.

This means that there is a lot of scope for Anna O , and it could be that the subjective opinions of the psychologist intrude in the assessment of what the data means.

For example, Freud has been criticized for producing case studies in which the information was sometimes distorted to fit particular behavioral theories (e.g., Little Hans ).

This is also true of Money’s interpretation of the Bruce/Brenda case study (Diamond, 1997) when he ignored evidence that went against his theory.

5 Compelling Alternatives to the Traditional Case Study Format

by John Cole | Aug 11, 2021 | Collateral , B2B Copywriting , Lead Generation , Case Studies | 0 comments

Case studies have long been one of the most popular and influential forms of marketing content.

In Eccolo Media’s annual B2B Technology Collateral Survey Report s (2008 to 2014), for example, technology buyers ranked case studies the second most influential content type – trailing only white papers – seven years in a row . 1 More recently, 60% of marketing influencers told Ascend2 that research and case studies are the content target audiences trust the most. 2

There’s really no surprise here. After all, case studies are short, quick reads. They’re familiar, easy to follow. They give technology buyers the information they need: solid evidence that they can succeed with your solution. And besides… everybody loves a good story.

But the traditional case study format has its drawbacks. It’s not always the perfect fit for every company, objective, audience, or customer story. And there’s a sameness to traditional case studies that makes it easy for them to get lost in the marketing message crowd.

So today, we’ll look at the advantages and disadvantages of a few “alternative” formats you may want to consider for your next success story project. Those I’ve chosen can all work well with technology-purchasing audiences. But before we explore the alternatives, let’s take a brief look at the pros and cons of the traditional case study.

The Traditional Case Study Format

We all know the traditional case study format. Four distinct sections under four well-known headings: Customer, Challenge (or Problem), Solution, and Results. They’re familiar to every B2B audience, easy to follow, easy to write.

So, what are the drawbacks of this tried-and-true formula?

Well, first of all, when you begin by describing the customer, it’s hard to get off to a compelling start. A good story provides some drama or intrigue right at the beginning to grab readers’ attention and pull them into the narrative. That drama comes from the customer’s challenge , not his background. Starting with a subject profile is not the best choice for some marketing objectives, like lead generation.

Second, the section headings offer no intrigue. They provide structure, but nothing to draw the attention of scanners. There’s no benefit. Besides, we’ve seen them all before.

Lastly, traditional case studies don’t appeal to trade journal editors. Editors want feature articles that resemble news stories, not academic papers or marketing pieces. If you want to get your case study placed in a trade magazine (or appeal to scanners or generate leads), you need a different format.

Five Alternative Case Study Formats

So, what are the alternatives to the traditional case study format? Here are five that can appeal to technology audiences.

1. The Feature Story

The “feature story” case study format is probably the most popular alternative to the traditional one. The reason it’s so popular? It addresses all the deficiencies of the traditional case study format.

As you’ve undoubtedly guessed, this type of case study is written like a feature story in a newspaper or magazine. It can follow the same logical sequence as the traditional form, but the information is not grouped under the standard subheads. Instead, the feature story case study employs techniques journalists use to engage readers, like descriptive subheads and an engaging opening paragraph, or “lead.”

To create drama in the lead, writers will typically start with the challenge, rather than a customer description. Background on the customer can either be sprinkled into the narrative—as a fiction author fleshes out characters—or placed in a sidebar. Descriptive subheads help to both summarize the story and pique the interest of scanners.

The big advantage of the feature story format is its engaging narrative flow. When well written, feature stories are more enjoyable to read and hold our attention better than traditional case studies. This makes them better for lead generation purposes. That’s also why trade editors like them. They look and read like other feature articles they publish.

The downside of the feature story format is that it requires greater writing skill. The writer must know how to handle key elements, like the headline, lead, and subheads. Story elements must be woven together into a cohesive narrative that flows relentlessly to a satisfying ending. If the reader gets lost, your success story will be a failure.

2. The Story-Within-A-Story

What could be better than a compelling, captivating success story? How about two?

The “story-within-a-story” is a variation of the feature story format. Along with describing why the customer chose your solution and how well it solved their problem, this case study format also includes an example of how your customer uses your solution to provide a better product or service to its own customers.

In other words, it contains a second case study that focuses on one of your customer’s customers.

This format can work very well if your market is OEMs, system integrators, or other vendors who incorporate your solution into their own. It’s also great for getting customer approval for your case study project and buy-in on joint marketing ventures; your customer gains publicity for one of their own successes. And like other feature stories, the story-within-a-story is ideal for trade journal placement and lead generation.

But with double the upside, you also get double the downside. This type of case study is more complex to produce. It involves additional interviews and approval cycles with your customer’s customer. Plus, crafting story-within-a-story calls for even greater writing skill than the feature story. Your writer needs to make sure the second story nests comfortably within the first without upsetting the flow of the narrative.

3. The Q&A

If you want a case study that can be created quickly and easily, consider the Q&A .

As the name suggests, a Q&A case study consists of a list of questions and the customer’s answers to each. While not a great lead-gen tool, Q&As can be very useful as website, blog, and newsletter content for nurturing leads and keeping customers engaged.

There are several advantages to the Q&A. The form is simple and doesn’t require great writing skills, so they’re quick and easy to produce. The questions, however, must be well thought out.

Q&A case studies are very appealing to technical audiences. Normally distrustful of marketing collateral, techies tend to like Q&As conducted with engineers or other technicians in roles similar to their own. They like getting no-nonsense information directly from their peers.

The downside here is that success is largely dependent on the quality of your customer’s responses to your questions. You need to pay a lot of attention to selecting the right customer rep for your interview. And your interviewer must be prepared to draw good information out of that person. There’s very little you can do in the editing process.

4. The First-Person Account

If your audience would respond well to a Q&A case study, but you want something you can place in a trade journal or use in lead generation campaigns, a “first-person” case study may fit the bill.

Like the Q&A, a first-person case study tells the story of a customer’s success with your solution in the customer’s own words. But the form is less rigid, more like that of a feature article. First-person case studies gain credibility by letting the reader hear the story “straight from the horse’s mouth” – like an extended testimonial.

First-person case studies are most often used by coaches and consultants who work with individuals. But they can succeed with corporate prospects as well, especially technical audiences. They tend to work best when the protagonist – the storyteller – had a big personal stake in the outcome of the story (had much to lose if the problem was not resolved, made or championed the purchase decision, etc).

What’s more, these individuals will often be more than willing to shepherd your case study through their own corporate approval process. After all, having a success story publicly documented can give a boost to one’s career.

Among the drawbacks of the first-person case study are that they can take longer to prepare, and they are not good for trade journal publication, due to the first-person perspective. They also have a potentially shorter shelf life. If the featured individual leaves the company, the customer might want the story discontinued.

Finally, a word of warning regarding first-person case studies: Don’t ask customers to write them themselves. Most won’t have the necessary writing skills or experience—let alone the time—to pull the project off. To create a story in the customer’s own words, your writer will need to prepare for a longer interview process and draw the full story out of the subject… without putting words in his or her mouth.

5. The Expected Results Story

Sometimes, it’s in a company’s interest to publish a case study before their customer has achieved any measurable results from their solution. This is called an “expected results” case study.

I wrote one of these recently. My client, an IT services company, had recently delivered Phase 1 of a three-phase project for a prestigious American university. We took an “expected results” approach for several reasons.

First, my client wanted to immediately leverage that success and the customer’s marquee name in their lead generation activities. But most of the measurable results of the project would not be realized until after the completion of Phase 3.

Second, Phase 1 had been the most critical phase of the project and held a very compelling story. It was a prime illustration of my client’s unique selling proposition and the reason the customer had chosen them for the job: the ability to deliver great results, on time and under budget, to an impossible deadline.

Third, while the customer had no problem with their name being used, the participation of a university representative in an interview was subject to a lengthy approval process. There was the possibility that customer participation and measurable results would never become available.

And finally, I would be interviewing members of my client’s technical staff, rather than the customer. Since staff members move quickly to other projects once a job is finished, my client wanted to document this project while it was still fresh in their minds.

Any of these circumstances would have been a good reason to proceed with an expected results story. Plus, there’s another great thing about this type of case study: it can be updated later, once the results are known.

The drawback of the expected results case study, of course, is that it has a weaker impact due to the lack of metrics. It forces you to make a case for your projected results. But if you have a compelling customer story and just lack hard results data, an expected results case study can let you leverage that story right away.

Takeaway Points

1. The traditional case study format (customer-challenge-solution-results) is still effective, but it can get lost in a crowd.

2. Traditional case studies are not always the best choice for every company, story, audience, or marketing objective.

3. Fortunately, you have a wide range of effective alternatives to the traditional case study format, including these five formats which work well with tech audiences:

• Feature story
• Story-within-a-story
• First-person
• Expected results

Program Management

A Business Case Analysis (BCA) is a document that provides a best-value analysis that considers not only cost but other quantifiable and non-quantifiable factors supporting an investment decision. A BCA should aid the decision maker in making an informed product support strategy decision. It should be tailored to inform the Program Manager of the costs, benefits, and risk implications of the strategic alternatives being considered. It should reflect the appropriate level of analysis needed to provide a fair assessment of the proposed alternatives. This analysis can include but is not limited to performance, producibility, reliability, maintainability, and supportability enhancements.

Definition: A Business Case Analysis (BCA) is a s a structured methodology and document that aids decision-making by identifying and comparing alternatives by examining the mission and business impacts (both financial and non-financial), risks, and sensitivities. It is a Program Management tool used to evaluate potential business decisions for best-value determinations.

Purpose of a Business Case Analysis (BCA)

The purpose of a BCA is to provide decision-makers with the appropriate information to assess whether or not to make a decision. A BCA is a valuable tool that assists in refining the myriad of decisions to determine the best value strategy.  It follows an iterative process, conducted and updated as needed throughout the life cycle as program plans evolve and react to changes in the business and mission environment.

Why Use a Business Case Analysis (BCA)

A BCA is a powerful tool for two crucial reasons. The first is that the person making the report has to think about all the costs, risks, and benefits of making a choice. When making a choice, it’s easy to only think about what you want to happen instead of looking at every possible event. When people are pushed to think about the worst possible outcomes, they are likelier to make the right choice. The second reason to use business case analysis is that it makes it easy for a subject-matter expert to give useful information to stakeholders and put it in context. Without a full report from the expert, stakeholders might not realize how vital some costs, risks, or rewards are.

Business Case Analysis (BCA) Use

A Business Case Analysis is used for the following:

• Is used in the initial decision to invest in a project.
• Guides the decision to select among alternative approaches.
• Is used to validate any proposed scope, schedule, or budget changes during the course of the project.
• Should also be used to identify the various budget accounts and amounts affected by the various product support strategies.
• Should be a living document ‘ as project or organization changes occur they should be reflected in updates to the business case.
• Should be used to validate that planned benefits are realized at the completion of the project.
• Makes the team consider all of the costs, risks, and benefits of making a decision

Business Case Analysis (BCA) Report Content

As a minimum, a BCA should include:

• Executive Summary: An overview of the BCA
• Introduction: An introduction that defines what the case is about (the subject) and why (its purpose) it is necessary. The introduction presents the objectives addressed by the subject of the case.
• Methods and Assumptions: state the analysis methods and rationale that fixes the boundaries of the case (whose costs and benefits are examined over what time period). This section outlines the rules for deciding what belongs in the case and what does not, along with the important assumptions.
• Impacts: The business impacts are the financial and non-financial business impacts expected in one or more scenarios.
• Risk assessment: show how results depend on important assumptions (‘what if’) and the likelihood for other results to surface.
• Conclusions and Recommendations: specific actions based on business objectives and the analysis results.

Performance-Based Logistics (PBL) BCA

DoD has promulgated the Guiding Principles for conducting a Performance-Based Logistics (PBL) BCA in USD(AT&L) Memorandum, Performance-Based Logistics (PBL) Business Case Analysis (BCA), 23 January 2004. OSD has issued guidance emphasizing the use of the Business Case Analysis as a fundamental tool to support PBL support strategic decisions.

Difference Between a Business Case and Business Case Analysis

They are the same regarding results, but a business case normally refers to the report, and business case analysis refers to the analysis.

Lessons Learned in Developing a Business Case Analysis (BCA)

As a program manager who needs to make a business case study for top management, there are a few essential things to remember. Here are some of the most important lessons:

• Know the Goals: Before you start the business case analysis, make sure you understand the company’s strategic goals and the proposed project’s specific goals. This will help you ensure your analysis aligns with the results you want and show senior leadership the possible value.
• Get people involved early: Include key partners from the start of the process to get their feedback and ensure their points of view are considered. Engaging partners early on builds support and helps find key success factors, possible risks, and other important factors that should be analyzed.
• Get enough information: Do a lot of studies and gather accurate information to back up your analysis. This includes financial data, market studies, customer feedback, and other useful information. Ensuring your data is correct and reliable will give your business case more weight.
• Clearly define assumptions: If you made any assumptions during the research, say so and explain them. Assumptions are a key part of making predictions and figuring out costs and rewards. Being open about your assumptions helps the people in charge understand your analysis and decide if it is true.
• List and measure the benefits: List and measure both the visible and invisible benefits of the planned project. Tangible benefits can be measured in terms of money, like how much they save, make, or improve efficiency. Some examples of intangible benefits are happier customers, a better image for the brand, and happier employees. Your business case will be stronger if you show all of the perks.
• Evaluate risks and ways to deal with them: Find and evaluate any possible risks with the project. Explain how likely risks will happen and how they might affect the company. Also, develop suitable mitigation strategies to show that you are taking a proactive approach to risk management and reduce the likelihood of bad things happening.
• Think about other options: Look into other solutions or ways of doing things and rate their viability and possible benefits. By comparing different options, senior leaders can make well-informed decisions and ensure that the planned initiative is the most effective and efficient way to meet organizational goals.
• Communicate clearly and briefly: Give your analysis in a clear, brief, and convincing way. Use visual guides, executive summaries, and other tools to help people understand your findings. Adjust the level of detail to your audience and focus on the key information senior leadership needs to make an informed choice.
• Be ready for questions: Think about what questions and worries senior leadership might have and be ready to answer them. Understand the business case analysis and the concepts it is based on so you can answer with confidence and knowledge. This shows your knowledge and builds your trustworthiness.
• Ask for feedback and keep making changes:  After presenting the business case analysis, ask top leadership and other stakeholders for feedback. Learn what they think and what worries them. Use this feedback as a chance to keep getting better, to improve your analysis, and to add useful information to future business cases.

Author networks in science often rely on citation analyses. In such cases, as in others, network interpretation usually depends on supplementary data, notably about authors’ research domains when disciplinary interpretations are sought. More general social networks also face similar interpretation challenges as to the semantic content specificities of their members. In this research-in-progress, we propose to infer author networks not from citation analyses but from topic similarity analyses based on a topic-model of published documents. Such author networks reveal, as we call them, “hidden communities of interest” (HCoIs) whose semantic content can easily be interpreted by means of their associated topics in the model. We use an astrobiology corpus of full-text articles ( N  = 3,698) to illustrate the approach. Having conducted an LDA topic-model on all publications, we identify the underlying communities of authors by measuring author correlations in terms of topic distributions. Adding publication dates makes it possible to examine HCoI evolution over time. This approach to social networks supplements traditional methods in contexts where textual data are available.

Metrics details

Case-based learning (CBL) methods have gained prominence in medical education, proving especially effective for preclinical training in undergraduate medical education. Tetralogy of Fallot (TOF) is a congenital heart disease characterized by four malformations, presenting a challenge in medical education due to the complexity of its anatomical pathology. Three-dimensional printing (3DP), generating physical replicas from data, offers a valuable tool for illustrating intricate anatomical structures and spatial relationships in the classroom. This study explores the integration of 3DP with CBL teaching for clinical medical undergraduates.

Sixty senior clinical medical undergraduates were randomly assigned to the CBL group and the CBL-3DP group. Computed tomography imaging data from a typical TOF case were exported, processed, and utilized to create four TOF models with a color 3D printer. The CBL group employed CBL teaching methods, while the CBL-3DP group combined CBL with 3D-printed models. Post-class exams and questionnaires assessed the teaching effectiveness of both groups.

The CBL-3DP group exhibited improved performance in post-class examinations, particularly in pathological anatomy and TOF imaging data analysis ( P  < 0.05). Questionnaire responses from the CBL-3DP group indicated enhanced satisfaction with teaching mode, promotion of diagnostic skills, bolstering of self-assurance in managing TOF cases, and cultivation of critical thinking and clinical reasoning abilities ( P  < 0.05). These findings underscore the potential of 3D printed models to augment the effectiveness of CBL, aiding students in mastering instructional content and bolstering their interest and self-confidence in learning.

The fusion of CBL with 3D printing models is feasible and effective in TOF instruction to clinical medical undergraduates, and worthy of popularization and application in medical education, especially for courses involving intricate anatomical components.

Peer Review reports

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease(CHD) [ 1 ]. Characterized by four structural anomalies: ventricular septal defect (VSD), pulmonary stenosis (PS), right ventricular hypertrophy (RVH), and overriding aorta (OA), TOF is a focal point and challenge in medical education. Understanding anatomical spatial structures is pivotal for learning and mastering TOF [ 2 ]. Given the constraints of course duration, medical school educators aim to provide students with a comprehensive and intuitive understanding of the disease within a limited timeframe [ 3 ].

The case-based learning (CBL) teaching model incorporates a case-based instructional approach that emphasizes typical clinical cases as a guide in student-centered and teacher-facilitated group discussions [ 4 ]. The CBL instructional methods have garnered widespread attention in medical education as they are particularly appropriate for preclinical training in undergraduate medical education [ 5 , 6 ]. The collection of case data, including medical records and examination results, is essential for case construction [ 7 ]. The anatomical and hemodynamic consequences of TOF can be determined using ultrasonography, computed tomography (CT), and magnetic resonance imaging techniques. However, understanding the anatomical structures from imaging data is a slow and challenging psychological reconstruction process for undergraduate medical students [ 8 ]. Three-dimensional (3D) visualization is valuable for depicting anatomical structures [ 9 ]. 3D printing (3DP), which creates physical replicas based on data, facilitates the demonstration of complex anatomical structures and spatial relationships in the classroom [ 10 ].

During the classroom session, 3D-printed models offer a convenient means for hands-on demonstration and communication, similar to facing a patient, enhancing the efficiency and specificity of intra-team communication and discussion [ 11 ]. In this study, we printed TOF models based on case imaging data, integrated them into CBL teaching, and assessed the effectiveness of classroom instruction.

Research participants

The study employed a prospective, randomized controlled design which received approval from the institutional ethics committee. Senior undergraduate students majoring in clinical medicine at Wannan Medical College were recruited for participation based on predefined inclusion criteria. The researchers implemented recruitment according to the recruitment criteria by contacting the class leaders of the target classes they had previously taught. Notably, these students were in their third year of medical education, with anticipation of progressing to clinical courses in the fourth year, encompassing Internal Medicine, Surgery, Obstetrics, Gynecology, and Pediatrics. Inclusion criteria for participants encompassed the following: (1) proficient communication and comprehension abilities, (2) consistent attendance without absenteeism or truancy, (3) absence of failing grades in prior examinations, and (4) capability to conscientiously fulfill assigned learning tasks. Exclusion criteria were (1) absence from lectures, (2) failure to complete pre-and post-tests, and (3) inadequate completion of questionnaires. For their participation in the study, Students were provided access to the e-book “Localized Anatomy,” authored by the investigators, as an incentive for their participation. Voluntary and anonymous participation was emphasized, with participants retaining the right to withdraw from the study at any time without providing a reason.

The study was conducted between May 1st, 2023, and June 30, 2023, from recruitment to completion of data collection. Drawing upon insights gained from a previous analogous investigation which yielded an effect size of 0.95 [ 10 ]. Sample size was computed, guided by a statistical consultant, with the aim of 0.85 power value, predicated on an effect size of 0.8 and a margin of error set at 0.05. A minimum of 30 participants per group was calculated using G*Power software (latest ver. 3.1.9.7; Heinrich-Heine-Universität Düsseldorf, Düsseldorf, Germany), resulting in the recruitment of a total of 60 undergraduate students. Each participant was assigned an identification number, with codes placed in boxes. Codes drawn from the boxes determined allocation to either the CBL group or the CBL-3DP group. Subsequently, participants were randomly assigned to either the CBL group, receiving instruction utilizing the CBL methodology, or the CBL-3DP group, which received instruction integrating both CBL and 3D Printed models.

Printing of TOF models

Figure  1 A shows the printing flowchart of the TOF models. A typical TOF case was collected from the Yijishan Hospital of Wannan Medical College. The CT angiography imaging data of the case was exported. Mimics Research 20.0 software (Mimics Innovation Suite version 20, Materialize, Belgium) was used for data processing. The cardiovascular module of the CT-Heart tool was employed to adjust the threshold range, independently obtain the cardiac chambers and vessels, post-process the chambers and vessels to generate a hollow blood pool, and merge it with the myocardial volume to construct a complete heart model. The file was imported into Magics 24.0 software (version 24.0; Materialize, Belgium) for correction using the Shell tool page. After repairs, the model entered the smoothing page, where tools such as triangular surface simplification, local smoothing, refinement and smoothing, subdivision of components, and mesh painting were utilized to achieve varying degrees of smoothness. Finally, optimized data were obtained and exported as stereolithography (STL) files. An experienced cardiothoracic surgeon validated the anatomical accuracy of the digital model.

The STL files were imported into a 3D printer (J401Pro; Sailner 3D Technology, China) for model printing. This printer can produce full-color medical models using different materials. The models were fabricated using two distinct materials: rigid and flexible. Both materials are suitable for the observational discussion of the teaching objectives outlined in our study. From the perspective of observing pathological changes in the TOF, there is no significant difference between the two materials.

Teaching implementation

Figure  1 B illustrates the instructional framework employed in this study. One week preceding the class session, all the students were tasked with a 30-minute self-study session, focusing on the theoretical content related to TOF as outlined in the Pediatrics and Surgery textbooks, along with a review of pertinent academic literature. Both groups received co-supervision from two basic medicine lecturers boasting over a decade of teaching experience, alongside a senior cardiothoracic surgeon. Teaching conditions remained consistent across groups, encompassing uniform assessment criteria and adherence to predefined teaching time frames, all conducted in a Project-Based Learning (PBL) classroom at Wannan Medical College. Additionally, a pre-course examination was administered to gauge students’ preparedness for self-study.

In adherence to the curriculum guidelines, the teaching objectives aimed to empower students to master TOF’s clinical manifestations, diagnostic modalities, and differential diagnoses, while acquainting them with treatment principles and surgical methodologies. Additionally, the objectives sought to cultivate students’ clinical reasoning abilities and problem-solving skills. the duration of instruction for the TOF theory session was standardized to 25 min. The didactic content was integrated with the TOF case study to construct a coherent pedagogical structure.

During the instructional session, both groups underwent teaching utilizing the CBL methodology. Clinical manifestations and case details of TOF cases were presented to stimulate students’ interest and curiosity. Subsequently, the theory of TOF, including its etiology, pathogenesis, pathologic anatomy, clinical manifestations, diagnostic methods, and therapeutic interventions, was briefly elucidated. Emphasis was then placed on the case, wherein selected typical TOF cases were explained, guiding students in analysis and discussion. Students were organized into four teams under the instructors’ supervision, fostering cooperative learning and communication, thereby deepening their understanding of the disease through continuous inquiry and exploration (Fig.  2 L). In the routinely equipped PBL classroom with standard heart models (Fig.  2 J, K), all students had prior exposure to human anatomy and were familiar with these models. Both groups were provided with four standard heart models for reference, while the CBL-3DP group received additional four 3D-printed models depicting TOF anomalies, enriching their learning experience (Fig.  2 D, G). After the lesson, summarization, and feedback sessions were conducted to consolidate group discussions’ outcomes, evaluate teaching effectiveness, and assess learning outcomes.

Teaching effectiveness assessment

Following the instructional session, participants from the two groups underwent a theoretical examination to assess their comprehension of the taught material. This assessment covered domains such as pathological anatomy, clinical manifestations, imaging data interpretation, diagnosis, and treatment relevant to TOF. Additionally, structured questionnaires were administered to evaluate the efficacy of the pedagogical approach employed. The questionnaire consisted of six questions designed to gauge participants’ understanding of the teaching content, enhancement of diagnostic skills, cultivation of critical thinking and clinical reasoning abilities, bolstering of confidence in managing TOF cases, satisfaction with the teaching mode, and satisfaction with the CBL methodology.

The questionnaire employed a 5-point Likert scale to gauge responses, with 5 indicating “strongly satisfied/agree,” 4 for “satisfied/agree,” 3 denoting “neutral,” 2 reflecting “dissatisfied/disagree,” and 1 indicating “strongly dissatisfied/disagree.” It comprised six questions, with the initial two probing participants’ knowledge acquisition, questions 3 and 4 exploring satisfaction regarding enhanced competence, and the final two assessing satisfaction with teaching methods and modes. Additionally, participants were encouraged to provide suggestions at the end of the questionnaire. To ensure the questionnaire’s validity, five esteemed lecturers in basic medical sciences with more than 10 years of experience verified its content and assessed its Content Validity Ratio and Content Validity Index to ensure alignment with the study’s objectives.

Statistical analysis

Statistical analyses were conducted utilizing GraphPad Prism 9.0 software. Aggregate score data for both groups were presented as mean ± standard deviation (x ± s). The gender comparisons were analyzed with the chi-square (χ2) test, while the other variables were compared using the Mann-Whitney U test. The threshold for determining statistical significance was set at P  < 0.05.

Three-dimensional printing models

After configuring the structural colors of each component (Fig.  2 A, B, C), we printed four color TOF models using both rigid and flexible materials, resulting in four life-sized TOF models. Two color TOF models were created using rigid materials (Fig.  2 D, E, F). These models, exhibiting resistance to deformation, and with a firm texture, smooth and glossy surface, and good transparency, allowing visibility of the internal structures, were deemed conducive to teaching and observation. We also fabricated two color TOF models using flexible materials (Fig.  2 G, H, I), characterized by soft texture, opacity, and deformability, allowing for easy manipulation and cutting. It has potential utility beyond observational purposes. It can serve as a valuable tool for simulating surgical interventions and may be employed to create tomographic anatomical specimens. In this study, both material models were suitable for observation in the classroom. The participants were able to discern the four pathological changes characteristic of TOF from surface examination or cross-sectional analysis.

Baseline characteristics of the students

In total, 60 students were included in this study. The CBL group comprised 30 students (14 males and 16 females), with an average age of (21.20 ± 0.76) years. The CBL-3DP group consisted of 30 students (17 males and 13 females) with an average age of 20.96 years. All the students completed the study procedures. There were no significant differences in age, sex ratio, or pre-class exam scores between the two groups ( P  > 0.05), indicating that the baseline scores between the two groups were comparable (Table  1 ).

Theoretical examination results

All students completed the research procedures as planned. The post-class theoretical examination encompassed assessment of pathological anatomy, clinical presentations, imaging data interpretation, diagnosis, and treatment pertinent to TOF. Notably, no statistically significant disparities were observed in the scores on clinical manifestations, diagnosis and treatment components between the cohorts, as delineated in Table  2 . Conversely, discernible distinctions were evident whereby the CBL-3DP group outperformed the CBL group notably in pathological anatomy, imaging data interpretation, and overall aggregate scores ( P  < 0.05).

Results of the questionnaires

All the 60 participants submitted the questionnaire. Comparing the CBL and CBL-3DP groups, the scores from the CBL-3DP group showed significant improvements in many areas. This included satisfaction with the teaching mode, promotion of diagnostic skills, bolstering of self-assurance in managing TOF cases, and cultivation of critical thinking and clinical reasoning abilities (Fig.  3 B, C, D, E). All of which improved significantly ( P  < 0.05 for the first aspects and P  < 0.01 for the rest). However, the two groups were not comparable ( P  > 0.05) in terms of understanding of the teaching content and Satisfaction with the CBL methodology (Fig.  3 A, F).

Upon completion of the questionnaires, participants were invited to proffer recommendations. Notably, in the CBL group, seven students expressed challenges in comprehending TOF and indicated a need for additional time for consolidation to enhance understanding. Conversely, within the CBL-3DP group, twelve students advocated for the augmentation of model repertoire and the expansion of disease-related data collection to bolster pedagogical efficacy across other didactic domains.

TOF presents a significant challenge in clinical practice, necessitating a comprehensive understanding for effective diagnosis and treatment [ 12 ]. Traditional teaching methods in medical schools have relied on conventional resources such as textbooks, 2D illustrations, cadaver dissections, and radiographic materials to impart knowledge about complex conditions like TOF [ 13 ]. However, the limitations of these methods in fully engaging students and bridging the gap between theoretical knowledge and practical application have prompted a need for innovative instructional approaches.

CBL has emerged as a valuable tool in medical education, offering students opportunities to engage with authentic clinical cases through group discussions and inquiry-based learning [ 14 ]. By actively involving students in problem-solving and decision-making processes, CBL facilitates the application of theoretical knowledge to real-world scenarios, thus better-preparing students for future clinical practice [ 15 ]. Our investigation revealed that both groups of students exhibited comparable levels of satisfaction with the CBL methodology, devoid of discernible disparities.

CHD presents a formidable challenge due to the intricate nature of anatomical anomalies, the diverse spectrum of conditions, and individual variations [ 16 ]. Utilizing 3D-printed physical models, derived from patient imaging data, can significantly enhance comprehension of complex anatomical structures [ 17 ]. These models have proven invaluable in guiding surgical planning, providing training for junior or inexperienced pediatric residents, and educating healthcare professionals and parents of patients [ 18 ]. Studies indicate that as much as 50% of pediatric surgical decisions can be influenced by the insights gained from 3D printed models [ 19 ]. By providing tangible, anatomically accurate models, 3D printing offers a unique opportunity for people to visualize complex structures and enhance their understanding of anatomical intricacies. Our study utilized full-color, to-scale 3D printed models to illustrate the structural abnormalities associated with TOF, thereby enriching classroom sessions and facilitating a deeper comprehension of the condition.

Comparative analysis between the CBL-3DP group and the CBL group revealed significant improvements in post-test performance, particularly in pathological anatomy and imaging data interpretation. Additionally, questionnaire responses indicated higher levels of satisfaction and confidence among students in the CBL-3DP group, highlighting the positive impact of incorporating 3D printed models into the learning environment, improving the effectiveness of CBL classroom instruction. Despite the merits, our study has limitations. Primarily, participants were exclusively drawn from the same grade level within a single college, possibly engendering bias owing to shared learning backgrounds. Future research could further strengthen these findings by expanding the sample size and including long-term follow-up to assess the retention of knowledge and skills. Additionally, the influence of the 3D models depicting a normal heart on the learning process and its potential to introduce bias into the results warrants consideration, highlighting a need for scrutiny in subsequent studies.

As medical science continues to advance, the need for effective teaching methods becomes increasingly paramount. Our study underscores the potential of combining active learning approaches like CBL with innovative technologies such as 3D printing to enhance teaching effectiveness, improve knowledge acquisition, and foster students’ confidence and enthusiasm in pursuing clinical careers. Moving forward, further research and integration of such methodologies are essential for meeting the evolving demands of medical education, especially in areas involving complex anatomical understanding.

Conclusions

Integrating 3D-printed models with the CBL method is feasible and effective in TOF instruction. The demonstrated success of this method warrants broad implementation in medical education, particularly for complex anatomical topics.
