An executive summary is a thorough overview of a research report or other type of document that synthesizes key points for its readers, saving them time and preparing them to understand the study's overall content. It is a separate, stand-alone document of sufficient detail and clarity to ensure that the reader can completely understand the contents of the main research study. An executive summary can be anywhere from 1-10 pages long depending on the length of the report, or it can be the summary of more than one document [e.g., papers submitted for a group project].

Importance of a Good Executive Summary

Although an executive summary is similar to an abstract in that they both summarize the contents of a research study, there are several key differences. With research abstracts, the author's recommendations are rarely included, or if they are, they are implicit rather than explicit. Recommendations are generally not stated in academic abstracts because scholars operate in a discursive environment, where debates, discussions, and dialogs are meant to precede the implementation of any new research findings. The conceptual nature of much academic writing also means that recommendations arising from the findings are distributed widely and not easily or usefully encapsulated. Executive summaries are used mainly when a research study has been developed for an organizational partner, funding entity, or other external group that participated in the research . In such cases, the research report and executive summary are often written for policy makers outside of academe, while abstracts are written for the academic community. Professors, therefore, assign the writing of executive summaries so students can practice synthesizing and writing about the contents of comprehensive research studies for external stakeholder groups.

When preparing to write, keep in mind that:

• An executive summary is not an abstract.
• An executive summary is not an introduction.
• An executive summary is not a preface.
• An executive summary is not a random collection of highlights.

Structure and Writing Style

Writing an Executive Summary

Read the Entire Document This may go without saying, but it is critically important that you read the entire research study thoroughly from start to finish before you begin to write the executive summary. Take notes as you go along, highlighting important statements of fact, key findings, and recommended courses of action. This will better prepare you for how to organize and summarize the study. Remember this is not a brief abstract of 300 words or less but, essentially, a mini-paper of your paper, with a focus on recommendations.

Isolate the Major Points Within the Original Document Choose which parts of the document are the most important to those who will read it. These points must be included within the executive summary in order to provide a thorough and complete explanation of what the document is trying to convey.

Separate the Main Sections Closely examine each section of the original document and discern the main differences in each. After you have a firm understanding about what each section offers in respect to the other sections, write a few sentences for each section describing the main ideas. Although the format may vary, the main sections of an executive summary likely will include the following:

• An opening statement, with brief background information,
• The purpose of research study,
• Method of data gathering and analysis,
• Overview of findings, and,
• A description of each recommendation, accompanied by a justification. Note that the recommendations are sometimes quoted verbatim from the research study.

Combine the Information Use the information gathered to combine them into an executive summary that is no longer than 10% of the original document. Be concise! The purpose is to provide a brief explanation of the entire document with a focus on the recommendations that have emerged from your research. How you word this will likely differ depending on your audience and what they care about most. If necessary, selectively incorporate bullet points for emphasis and brevity. Re-read your Executive Summary After you've completed your executive summary, let it sit for a while before coming back to re-read it. Check to make sure that the summary will make sense as a separate document from the full research study. By taking some time before re-reading it, you allow yourself to see the summary with fresh, unbiased eyes.

Common Mistakes to Avoid

Length of the Executive Summary As a general rule, the correct length of an executive summary is that it meets the criteria of no more pages than 10% of the number of pages in the original document, with an upper limit of no more than ten pages [i.e., ten pages for a 100 page document]. This requirement keeps the document short enough to be read by your audience, but long enough to allow it to be a complete, stand-alone synopsis. Cutting and Pasting With the exception of specific recommendations made in the study, do not simply cut and paste whole sections of the original document into the executive summary. You should paraphrase information from the longer document. Avoid taking up space with excessive subtitles and lists, unless they are absolutely necessary for the reader to have a complete understanding of the original document. Consider the Audience Although unlikely to be required by your professor, there is the possibility that more than one executive summary will have to be written for a given document [e.g., one for policy-makers, one for private industry, one for philanthropists]. This may only necessitate the rewriting of the introduction and conclusion, but it could require rewriting the entire summary in order to fit the needs of the reader. If necessary, be sure to consider the types of audiences who may benefit from your study and make adjustments accordingly. Clarity in Writing One of the biggest mistakes you can make is related to the clarity of your executive summary. Always note that your audience [or audiences] are likely seeing your research study for the first time. The best way to avoid a disorganized or cluttered executive summary is to write it after the study is completed. Always follow the same strategies for proofreading that you would for any research paper. Use Strong and Positive Language Don’t weaken your executive summary with passive, imprecise language. The executive summary is a stand-alone document intended to convince the reader to make a decision concerning whether to implement the recommendations you make. Once convinced, it is assumed that the full document will provide the details needed to implement the recommendations. Although you should resist the temptation to pad your summary with pleas or biased statements, do pay particular attention to ensuring that a sense of urgency is created in the implications, recommendations, and conclusions presented in the executive summary. Be sure to target readers who are likely to implement the recommendations.

How To Write A High-Impact Executive Summary

By Derek Jansen | January 2018

In this post, I’ll deconstruct the often-misunderstood executive summary and show you how to develop a high-impact executive summary for your assignment, research report or even your dissertation or thesis.

So, what is an executive summary?

An executive summary (sometimes called an abstract ) is quite simply a summary of summaries. In other words, an executive summary provides a concise summary of each of your assignment or report chapters/sections . More specifically, it should communicate the key points/insights/findings/suggestions from the following chapters:

• Introduction
• Recommendations
• Implementation (if applicable)
• Reflection (if applicable)

I’ll discuss which key points from each section need to be addressed a bit later. On a separate note – if you’re writing an executive summary for a dissertation or thesis, all of the concepts described in this post will still apply to you, however, you’ll include an additional paragraph about your methodology, and you’ll likely spend more word count discussing your analysis findings.

The 4 Important Attributes Of An Exec Summary

Before I discuss what goes into the executive summary, let’s quickly look at 4 attributes that make for a strong executive summary:

#1 – It should be able to stand alone.

The executive summary should be able to stand independently as an informative document . In other words, the reader should be able to grasp your broad argument without having to read the full document. Further reading should be purely for attaining more detail. Simply put, the executive summary should be a “Mini-Me” of the assignment.

This independence means that anything you write in the executive summary will need to be re-stated in the body of your assignment. A common mistake that students make is to introduce key points in the executive summary and then not discuss them again in the document – accordingly, the marker must view the main document as missing these key points. Simply put – make sure you discuss key points in both the executive summary and the main body . It will feel repetitive at times – this is normal.

#2 – It should be written for the intelligent layman.

When crafting your executive summary, its useful to keep the intelligent layman front of mind. What I mean by this is that you should write your summary assuming that your reader (i.e. the marker) will be intelligent but won’t be familiar with your topic and/or industry. This means that you should explain any technical concepts, avoid jargon and explain acronyms before using them.

#3 – It should be concise.

Typically, your executive summary should be a one-pager (one and a half pages at worst). To summarise a 3000 – 5000-word document into one page is no easy task, so you’ll need to:

• Present only the most important information (key insights, recommendations, etc).
• Write concisely – i.e. with brevity and completeness.

To the first point, I’ll explain what the “most important” information is for each chapter shortly. To the second point (writing concisely), there are various ways to do this, including:

• Using simple, straightforward language.
• Using the active voice.
• Removing bloaty adverbs and adjectives.
• Reducing prepositional phrases.
• Avoiding noun strings.

Does this sound like gibberish to you? Don’t worry! The Writing Center at the University of Wisconson-Madison provides a practical guide to writing more concisely, which you can download here.

On a related note, you typically would not include headings, citations or bulleted/numbered lists in your executive summary. These visual components tend to use a lot of space, which comes at a premium, as you know.

#4 – It should be written last.

Given that your executive summary is a summary of summaries, it needs to be written last , only once you’ve identified all your key insights, recommendations and so on. This probably sounds obvious, but many students start writing the summary first (potentially because of its position in the document) and then end up re-writing it multiple times, or they don’t rewrite it and consequently end up with an executive summary which is misaligned with the main document.

Simply put, you should leave this section until everything else is completed. Once your core body content is completed, you should read through the entire document again and create a bullet-point list of all the key points . From this list, you should then craft your executive summary . The approach will also help you identify gaps, contradictions and misalignments in your main document.

So, what goes into an executive summary?

Right, let’s get into the meat of it and consider what exactly should go into your executive summary. As I’ve mentioned, you need to present only the absolutely key point points from each of your chapters, but what does this mean exactly?

Each chapter will typically take the form of 1 paragraph (with no headings) in your executive summary. So, 5 chapters means 5 paragraphs. Naturally, some will be longer than others (let this be informed by the mark allocation), but assuming one page contains 500 words, you’re aiming for roughly 100 words per paragraph (assuming a 5-paragraph structure). See why conciseness is key!

Now, let’s look at what the key points are for each chapter in the case of a typical MBA assignment or report. In the case of a dissertation or thesis, the paragraph structure would still mimic the chapter structure – you’d just have more chapters, and therefore, more paragraphs.

Paragraph 1: Introduction

This paragraph should cover the following points:

• A very brief explanation of the business (what does it do, for whom and where?).
• Clear identification and explanation of the problem or opportunity that will be the focus of the assignment/report.
• A clear statement of the purpose of the assignment (i.e. what research questions will you seek to answer?).
• Brief mention of what data sources were utilised (i.e. secondary research) and any fieldwork undertaken (i.e. primary research ).

In other words, your first paragraph should introduce the business, the problem/opportunity to be addressed, why it’s important, and how you approached your analysis. This paragraph should make it clear to the reader what the assignment is all about at a broad level. Here’s a practical example:

This assignment focuses on ABC Ltd, a XXX business based in XXX, which provides XXX to XXX customers. To date, the firm has relied almost exclusively on XXX marketing channel. Consequently, ABC Ltd has little understanding of consumer segments, wants, and needs. This marketing channel is now under regulatory threat due to XXX.  The core challenge, therefore, is that whilst ABC Ltd seeks to grow its market share, it has little understanding of its market characteristics or competitive set, and its sole marketing channel under regulatory threat. Accordingly, the objective of this assignment is XXX. The assignment draws on survey, interview, and industry data.

Paragraph 2: Analysis and findings

In this paragraph, you should discuss the following:

• What exactly did you analyse? For example, you might have analysed the macro context (i.e. PESTLE analysis), followed by the meso (i.e. competitor or industry analysis) and then the micro (i.e. internal organisational analysis).
• What were your key findings in relation to the purpose of the assignment? For example, you may have identified 4 potential causes of a problem and would then state them.

In other words, your second paragraph should concisely explain what you analysed and what your main findings were . An example of this:

Segmentation analysis, consisting of macro, industry and firm-level analyses, revealed a strong segmentation variable in the form of XXX, with distinct needs in each segment. Macro analysis revealed XXX, while industry and firm-level analyses suggested XXX. Subsequently, three potential target segments were established, namely XXX, XXX and XXX.  These were then evaluated using the Directional Policy Matrix, and the results indicated XXX.

From a presentation perspective, you might structure this section as:

• Analysis 1, findings from analysis 1.
• Analysis 2, findings from analysis 2.
• Analysis 3, findings from analysis 3.

Importantly, you should only discuss the findings that are directly linked to the research questions (i.e. the purpose of the assignment) – don’t digress into interesting but less relevant findings. Given that the analysis chapter typically counts for a large proportion of marks, you could viably write 2-3 paragraphs for this. Be guided by the mark allocation.

Lastly, you should ensure that the findings you present here align well with the recommendations you’ll make in the next paragraph. Think about what your recommendations are, and, if necessary, reverse engineer this paragraph to create a strong link and logical flow from analysis to recommendations.

Paragraph 3: Recommendations

With the key findings from your analysis presented in the preceding paragraph, you should now discuss the following:

• What are your key recommendations?
• How do these solve the problems you found in your analysis?
• Were there any further conclusions?

Simply put, this paragraph (or two) should present the main recommendations and justify their use (i.e. explain how they resolve the key issue). As mentioned before, it’s critically important that your recommendations tightly align with (and resolve) the key issues that you identified in the analysis. An example:

Based on the Directional Policy Matrix analysis, it is recommended that the firm target XXX segment, because of XXX. On this basis, a positioning of XXX is proposed, as this aligns with the segment’s key needs. Furthermore, a provisional high-level marketing mix is proposed. The key aspects of the marketing mix include XXX, XXX and XXX, as these align with the firm’s positioning of XXX. By adopting these recommendations, the key issue of XXX will be resolved.

Also, note that (typically) the tone changes from past to present tense when you get to the recommendations section.

Paragraph 4: Implementation

If your assignment brief requires an implementation/project plan-type section, this paragraph will typically include the following points:

• Time requirements (how long will it take?)
• People requirements (what skills are needed and where do you find them?)
• Money requirements (what budget is required?)
• How will the project or change be managed? (i.e. project management plan)
• What risks exist and how will these be managed?

Depending on what level of detail is required by your assignment brief, you may need to present more, less or other details in this section. As always, be guided by the assignment brief.

A practical example:

A high-level implementation plan is proposed, including a stakeholder analysis, project plan and business case. Resource requirements are presented, detailing XXX, XXX and XXX requirements. A risk analysis is presented, revealing key risks including XXX, XXX and XXX. Risk management solutions are proposed, including XXX and XXX.  

Paragraph 5: Reflection

As with the implementation chapter, the need for a reflection chapter/section will vary between assignments and universities. If your assignment has this requirement, it’s typically good to cover the following points:

• What were your key learnings? What were your ah-ha moments?
• What has changed in the real world as a consequence of these learnings? I.e. how has your actual behaviour and approach to “X” changed, if any?
• What are the benefits and/or disadvantages of this change, if any?

This section is very personal, and so each person’s reflections will be different. Don’t take the above points as gospel.

Time to test it out.

Once you’ve written up your executive summary and feel confident that it’s in good shape, it’s time to test it out on an unsuspecting intelligent layman. This is a critically important step, since you, as the writer, are simply too close to the work to judge whether it all makes sense to a first-time reader. In fact, you are the least suitable person on the planet!

So, find someone who is not familiar with your assignment topic (and ideally, not familiar with your industry), and ask them to have a read through your executive summary. Friends and family will usually tell you its great, regardless of the quality, so you need to test them on their understanding. Do this by asking them to give the details back to you in their own words. Poke and prod – can they tell you what the key issues and recommendations were (in their own words!). You’ll quickly spot the gaps this way, and be able to flesh out any weak areas.

  Wrapping up.

In this post, I’ve discussed how to write the all too often undercooked executive summary. I’ve discussed some important attributes of a strong executive summary, as well as the contents that typically go into it. To recap on the key points:

The key attributes of a high-impact executive summary:

• It should be able to stand alone.
• It should be written for the intelligent layman.
• It should be concise.
• It should be written last.

The key contents of a high-impact executive summary:

Each paragraph should cover a chapter from the document. For example, In the case of a typical assignment, it would be something like:

• Summary of the introduction chapter.
• Summary of the analysis chapter.
• Summary of the recommendations and/or conclusions chapter.
• Depending – summary of the implementation and reflection.

Lastly, don’t forget to test out your executive summary on an unsuspecting layman or two. This is probably the most important step of them all!

What is a Literature Review? | Guide, Template, & Examples

Published on 22 February 2022 by Shona McCombes . Revised on 7 June 2022.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research.

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarise sources – it analyses, synthesises, and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Quick Run-through
• Step 1 & 2

When you write a dissertation or thesis, you will have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and scholarly context
• Develop a theoretical framework and methodology for your research
• Position yourself in relation to other researchers and theorists
• Show how your dissertation addresses a gap or contributes to a debate

You might also have to write a literature review as a stand-alone assignment. In this case, the purpose is to evaluate the current state of research and demonstrate your knowledge of scholarly debates around a topic.

The content will look slightly different in each case, but the process of conducting a literature review follows the same steps. We’ve written a step-by-step guide that you can follow below.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

You can use our free APA Reference Generator for quick, correct, consistent citations.

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.

There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.

Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

• Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
• Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, discussing the significance of findings in relation to the literature as a whole.
• Critically evaluate: mention the strengths and weaknesses of your sources.
• Write in well-structured paragraphs: use transitions and topic sentences to draw connections, comparisons and contrasts.

In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a dissertation , thesis, research paper , or proposal .

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarise yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your  dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

Executive summaries and abstracts both capture the essence of a project in a shorter form, but with differing levels of detail: an abstract is a highly condensed overview of the document, while an executive summary is a standalone version of the thesis in miniature.

See our handout on " What Goes in a Thesis Abstract? An Executive Summary? " for an overview of standard content and length—then, for more information and examples, read on!

For a more detailed explanation of abstracts, check out our infographics, tailored to your discipline:

• Defense management
• Social sciences

An abstract is a brief encapsulation of a document. Abstracts are quite limited in length (often about 200 words) and thus must be very concise, clear statements that convey a few key ideas:

• The topic and significance of the research
• The research question driving the inquiry
• The methods used to answer the question
• The findings and implications of the research

Understanding how an abstract is structured can also help you as a researcher. When conducting research , get in the habit of reading abstracts carefully to determine which documents closely fit your research needs.

Not all documents require an abstract, and most of your class papers won't. However, all NPS theses must have an abstract, and abstracts are often required for conference papers and articles submitted for publication .

Executive Summaries

Executive summaries are longer than abstracts, often running 2–5 pages. They summarize a larger document's purpose, methods, results, conclusions, and recommendations such that someone who reads  only the summary can glean a solid understanding of the research as a whole. Unlike abstracts, executive summaries can include citations and references .

Not all theses require an executive summary, so check with your advisor or department for guidance. The links below contain further information on the differences between abstracts and executive summaries.

In order to make your research easier to find by other researchers, it is a good idea to think about what searchable keywords are associated with your project. Make sure to include them in your abstract and executive summary!

Common Assignments: Executive Summaries

Basics of executive summaries.

Executive summaries are common in the Walden MBA program, but they are also found as part of some government and business documents. As a student, you should complete an executive summary when specifically requested to do so. An executive summary is a comprehensive review of a larger document. For example, a 35-page report may begin with a single-page executive summary all of the main information in the longer report. Any findings, conclusions, recommendations, or other details that appear in the larger document must be touched on in the executive summary. Readers should be able to read the executive summary alone and have a complete understanding of the larger document in its entirety.

How to Write an Executive Summary

It is important to meet all length and content expectations, so be sure to review the specific directions for your assignment. Also remember that the executive summary can only be written after the full-length document is complete.

Tips for completing the executive summary from Walden University (2013) include:

• List all of the main points in the same order in which they occur in the paper that you are summarizing.
• Take each point and turn it into a sentence.
• Add additional sentences to clarify or explain each point.
• Add a short introduction and a short conclusion. Include the name of the article, report, etc. and the author(s) in the introduction.
• Check grammar, spelling, and punctuation.
• Check for plagiarism.
• Read the summary slowly and carefully to make sure it covers all of the main points clearly, yet concisely. Also, check to be sure it is interesting. You want to catch your reader’s attention.
• Set it aside. Let some time pass and read it again. Often, you will catch items that you did not see the first time.

For academic writing, be sure to include appropriate citations and a reference. This is typically not part of a business executive summary but should be included for purposes of this program.

Executive Summary Versus Abstract

Like an executive summary, an abstract is a short summary of a larger text. Both executive summaries and abstracts are meant to capture the main ideas, findings, and conclusions of a longer document.  Executive summaries, however, tend to include more details than abstracts. An abstract includes enough information for readers to decide if they want to read the full-length document. Executive summaries must include enough information for readers to understand the full-length document without reading it.

Another difference between executive summaries and abstracts are the fields where they are used. Generally, executive summaries are common in business and government, while abstracts are more common in academia and at Walden, especially when seeking publication in a professional journal.

What is a Literature Review?

A literature or narrative review is a comprehensive review and analysis of the published literature on a specific topic or research question. The literature that is reviewed contains: books, articles, academic articles, conference proceedings, association papers, and dissertations. It contains the most pertinent studies and points to important past and current research and practices. It provides background and context, and shows how your research will contribute to the field. 

A literature review should: 

• Provide a comprehensive and updated review of the literature;
• Explain why this review has taken place;
• Articulate a position or hypothesis;
• Acknowledge and account for conflicting and corroborating points of view

From  S age Research Methods

Purpose of a Literature Review

A literature review can be written as an introduction to a study to:

• Demonstrate how a study fills a gap in research
• Compare a study with other research that's been done

Or it can be a separate work (a research article on its own) which:

• Organizes or describes a topic
• Describes variables within a particular issue/problem

Limitations of a Literature Review

Some of the limitations of a literature review are:

• It's a snapshot in time. Unlike other reviews, this one has beginning, a middle and an end. There may be future developments that could make your work less relevant.
• It may be too focused. Some niche studies may miss the bigger picture.
• It can be difficult to be comprehensive. There is no way to make sure all the literature on a topic was considered.
• It is easy to be biased if you stick to top tier journals. There may be other places where people are publishing exemplary research. Look to open access publications and conferences to reflect a more inclusive collection. Also, make sure to include opposing views (and not just supporting evidence).

The Report Abstract and Executive Summary

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

The Abstract

The abstract is a crucial part of your report as it may be the only section read by people at the executive or managerial level who must make decisions based on what they read in your abstract. When you include specific content, it is important to remember these readers are looking for the information they need to make decisions.

The abstract is an overview that provides the reader with the main points and results, though it is not merely a listing of what the report contains. It is a summary of the essence of a report. For this reason, it should be crafted to present the most complete and compelling information possible. It is not a detective story building suspense as the reader hunts for clues, and should not be vague or obtuse in its content.

The abstract should include

• Why the work was done (the basic problem), the specific purpose or objective, and the scope of the work if that is relevant. (College lab reports may not require this part of the abstract.)
• How the work was done, the test methods or means of investigation
• What was found—the results, conclusions, and recommendations

The abstract should

• Not make references to material in the text
• Not lose the message by burying the methods, results, conclusions, and recommendations in a sea of words
• Not be written before the rest of the report

Therefore, a good abstract is

• Self-sufficient

Evaluating abstracts

Because the abstract is of major importance in a report, a summary of effective qualities of abstracts is offered here.

A well-written abstract

• Considers the readers it will encounter
• States what was done and what results were found
• Avoids vagueness by stating specific results
• Uses past tense to report what was done
• Is informative
• Is self-sufficient and does not refer to the body of the report
• Makes concrete, useful recommendations

Below are two abstracts. The first one, (A), was written by a student for a lab report, and the other one (B) was a revision written by someone with more experience in writing abstracts. Read both versions and try to figure out why the changes were made in B.

We studied the flow characteristics of meters, valves, and pipes that constitute a flow network. The meter coefficients for orifice and venture meters were determined. The orifice and venture coefficients were, on the average, 0.493 and 0.598, respectively. Fanning friction factors for pipes of different sizes and for gate and globe valves were also determined.

The accuracy with which the meter coefficients and friction factors were determined was affected by leaks in the piping network. In addition, air bubbles trapped in the pipes and manometers affected the accuracy with which pressure drops were measured. Hence, it is recommended that the piping system be checked to ensure the absence of any leaks. Furthermore, the fluid should be allowed to flow in the network for some time before taking any measurements, in order to get rid of the air trapped in the pipes and manometer.

In an orifice and a venturimeter in a flow network, we measured the meter coefficients to be 0.5 0.1 and 0.6 0.15. We measured the Fanning friction factors at steady state for several pipes and for gate and globe valves. The most important source of error was a leak in the piping network which has to be repaired in order to obtain more precise results.

The Executive Summary

The government and some companies have begun to request executive summaries at the beginning of a long report. An executive summary is a one-page statement of the problem, the purpose of the communication, and a summary of the results, conclusions, and recommendations. The same considerations of readers and situation should guide your executive summaries.

The term case study refers to both a method of analysis and a specific research design for examining a problem, both of which are used in most circumstances to generalize across populations. This tab focuses on the latter--how to design and organize a research paper in the social sciences that analyzes a specific case.

A case study research paper examines a person, place, event, phenomenon, or other type of subject of analysis in order to extrapolate  key themes and results that help predict future trends, illuminate previously hidden issues that can be applied to practice, and/or provide a means for understanding an important research problem with greater clarity. A case study paper usually examines a single subject of analysis, but case study papers can also be designed as a comparative investigation that shows relationships between two or among more than two subjects. The methods used to study a case can rest within a quantitative, qualitative, or mixed-method investigative paradigm.

How to Approach Writing a Case Study Research Paper

General information about how to choose a topic to investigate can be found under the " Choosing a Research Problem " tab in this writing guide. Review this page because it may help you identify a subject of analysis that can be investigated using a single case study design.

However, identifying a case to investigate involves more than choosing the research problem . A case study encompasses a problem contextualized around the application of in-depth analysis, interpretation, and discussion, often resulting in specific recommendations for action or for improving existing conditions. As Seawright and Gerring note, practical considerations such as time and access to information can influence case selection, but these issues should not be the sole factors used in describing the methodological justification for identifying a particular case to study. Given this, selecting a case includes considering the following:

• Does the case represent an unusual or atypical example of a research problem that requires more in-depth analysis? Cases often represent a topic that rests on the fringes of prior investigations because the case may provide new ways of understanding the research problem. For example, if the research problem is to identify strategies to improve policies that support girl's access to secondary education in predominantly Muslim nations, you could consider using Azerbaijan as a case study rather than selecting a more obvious nation in the Middle East. Doing so may reveal important new insights into recommending how governments in other predominantly Muslim nations can formulate policies that support improved access to education for girls.
• Does the case provide important insight or illuminate a previously hidden problem? In-depth analysis of a case can be based on the hypothesis that the case study will reveal trends or issues that have not been exposed in prior research or will reveal new and important implications for practice. For example, anecdotal evidence may suggest drug use among homeless veterans is related to their patterns of travel throughout the day. Assuming prior studies have not looked at individual travel choices as a way to study access to illicit drug use, a case study that observes a homeless veteran could reveal how issues of personal mobility choices facilitate regular access to illicit drugs. Note that it is important to conduct a thorough literature review to ensure that your assumption about the need to reveal new insights or previously hidden problems is valid and evidence-based.
• Does the case challenge and offer a counter-point to prevailing assumptions? Over time, research on any given topic can fall into a trap of developing assumptions based on outdated studies that are still applied to new or changing conditions or the idea that something should simply be accepted as "common sense," even though the issue has not been thoroughly tested in practice. A case may offer you an opportunity to gather evidence that challenges prevailing assumptions about a research problem and provide a new set of recommendations applied to practice that have not been tested previously. For example, perhaps there has been a long practice among scholars to apply a particular theory in explaining the relationship between two subjects of analysis. Your case could challenge this assumption by applying an innovative theoretical framework [perhaps borrowed from another discipline] to the study a case in order to explore whether this approach offers new ways of understanding the research problem. Taking a contrarian stance is one of the most important ways that new knowledge and understanding develops from existing literature.
• Does the case provide an opportunity to pursue action leading to the resolution of a problem? Another way to think about choosing a case to study is to consider how the results from investigating a particular case may result in findings that reveal ways in which to resolve an existing or emerging problem. For example, studying the case of an unforeseen incident, such as a fatal accident at a railroad crossing, can reveal hidden issues that could be applied to preventative measures that contribute to reducing the chance of accidents in the future. In this example, a case study investigating the accident could lead to a better understanding of where to strategically locate additional signals at other railroad crossings in order to better warn drivers of an approaching train, particularly when visibility is hindered by heavy rain, fog, or at night.
• Does the case offer a new direction in future research? A case study can be used as a tool for exploratory research that points to a need for further examination of the research problem. A case can be used when there are few studies that help predict an outcome or that establish a clear understanding about how best to proceed in addressing a problem. For example, after conducting a thorough literature review [very important!], you discover that little research exists showing the ways in which women contribute to promoting water conservation in rural communities of Uganda. A case study of how women contribute to saving water in a particular village can lay the foundation for understanding the need for more thorough research that documents how women in their roles as cooks and family caregivers think about water as a valuable resource within their community throughout rural regions of east Africa. The case could also point to the need for scholars to apply feminist theories of work and family to the issue of water conservation.

Structure and Writing Style

The purpose of a paper in the social sciences designed around a case study is to thoroughly investigate a subject of analysis in order to reveal a new understanding about the research problem and, in so doing, contributing new knowledge to what is already known from previous studies. In applied social sciences disciplines [e.g., education, social work, public administration, etc.], case studies may also be used to reveal best practices, highlight key programs, or investigate interesting aspects of professional work. In general, the structure of a case study research paper is not all that different from a standard college-level research paper. However, there are subtle differences you should be aware of. Here are the key elements to organizing and writing a case study research paper.

I.  Introduction

As with any research paper, your introduction should serve as a roadmap for your readers to ascertain the scope and purpose of your study . The introduction to a case study research paper, however, should not only describe the research problem and its significance, but you should also succinctly describe why the case is being used and how it relates to addressing the problem. The two elements should be linked. With this in mind, a good introduction answers these four questions:

• What was I studying? Describe the research problem and describe the subject of analysis you have chosen to address the problem. Explain how they are linked and what elements of the case will help to expand knowledge and understanding about the problem.
• Why was this topic important to investigate? Describe the significance of the research problem and state why a case study design and the subject of analysis that the paper is designed around is appropriate in addressing the problem.
• What did we know about this topic before I did this study? Provide background that helps lead the reader into the more in-depth literature review to follow. If applicable, summarize prior case study research applied to the research problem and why it fails to adequately address the research problem. Describe why your case will be useful. If no prior case studies have been used to address the research problem, explain why you have selected this subject of analysis.
• How will this study advance new knowledge or new ways of understanding? Explain why your case study will be suitable in helping to expand knowledge and understanding about the research problem.

Each of these questions should be addressed in no more than a few paragraphs. Exceptions to this can be when you are addressing a complex research problem or subject of analysis that requires more in-depth background information.

II.  Literature Review

The literature review for a case study research paper is generally structured the same as it is for any college-level research paper. The difference, however, is that the literature review is focused on providing background information and  enabling historical interpretation of the subject of analysis in relation to the research problem the case is intended to address . This includes synthesizing studies that help to:

• Place relevant works in the context of their contribution to understanding the case study being investigated . This would include summarizing studies that have used a similar subject of analysis to investigate the research problem. If there is literature using the same or a very similar case to study, you need to explain why duplicating past research is important [e.g., conditions have changed; prior studies were conducted long ago, etc.].
• Describe the relationship each work has to the others under consideration that informs the reader why this case is applicable . Your literature review should include a description of any works that support using the case to study the research problem and the underlying research questions.
• Identify new ways to interpret prior research using the case study . If applicable, review any research that has examined the research problem using a different research design. Explain how your case study design may reveal new knowledge or a new perspective or that can redirect research in an important new direction.
• Resolve conflicts amongst seemingly contradictory previous studies . This refers to synthesizing any literature that points to unresolved issues of concern about the research problem and describing how the subject of analysis that forms the case study can help resolve these existing contradictions.
• Point the way in fulfilling a need for additional research . Your review should examine any literature that lays a foundation for understanding why your case study design and the subject of analysis around which you have designed your study may reveal a new way of approaching the research problem or offer a perspective that points to the need for additional research.
• Expose any gaps that exist in the literature that the case study could help to fill . Summarize any literature that not only shows how your subject of analysis contributes to understanding the research problem, but how your case contributes to a new way of understanding the problem that prior research has failed to do.
• Locate your own research within the context of existing literature [very important!] . Collectively, your literature review should always place your case study within the larger domain of prior research about the problem. The overarching purpose of reviewing pertinent literature in a case study paper is to demonstrate that you have thoroughly identified and synthesized prior studies in the context of explaining the relevance of the case in addressing the research problem.

III.  Method

In this section, you explain why you selected a particular subject of analysis to study and the strategy you used to identify and ultimately decide that your case was appropriate in addressing the research problem. The way you describe the methods used varies depending on the type of subject of analysis that frames your case study.

If your subject of analysis is an incident or event . In the social and behavioral sciences, the event or incident that represents the case to be studied is usually bounded by time and place, with a clear beginning and end and with an identifiable location or position relative to its surroundings. The subject of analysis can be a rare or critical event or it can focus on a typical or regular event. The purpose of studying a rare event is to illuminate new ways of thinking about the broader research problem or to test a hypothesis. Critical incident case studies must describe the method by which you identified the event and explain the process by which you determined the validity of this case to inform broader perspectives about the research problem or to reveal new findings. However, the event does not have to be a rare or uniquely significant to support new thinking about the research problem or to challenge an existing hypothesis. For example, Walo, Bull, and Breen conducted a case study to identify and evaluate the direct and indirect economic benefits and costs of a local sports event in the City of Lismore, New South Wales, Australia. The purpose of their study was to provide new insights from measuring the impact of a typical local sports event that prior studies could not measure well because they focused on large "mega-events." Whether the event is rare or not, the methods section should include an explanation of the following characteristics of the event: a) when did it take place; b) what were the underlying circumstances leading to the event; c) what were the consequences of the event.

If your subject of analysis is a person. Explain why you selected this particular individual to be studied and describe what experience he or she has had that provides an opportunity to advance new understandings about the research problem. Mention any background about this person which might help the reader understand the significance of his/her experiences that make them worthy of study. This includes describing the relationships this person has had with other people, institutions, and/or events that support using him or her as the subject for a case study research paper. It is particularly important to differentiate the person as the subject of analysis from others and to succinctly explain how the person relates to examining the research problem.

If your subject of analysis is a place. In general, a case study that investigates a place suggests a subject of analysis that is unique or special in some way and that this uniqueness can be used to build new understanding or knowledge about the research problem. A case study of a place must not only describe its various attributes relevant to the research problem [e.g., physical, social, cultural, economic, political, etc.], but you must state the method by which you determined that this place will illuminate new understandings about the research problem. It is also important to articulate why a particular place as the case for study is being used if similar places also exist [i.e., if you are studying patterns of homeless encampments of veterans in open spaces, why study Echo Park in Los Angeles rather than Griffith Park?]. If applicable, describe what type of human activity involving this place makes it a good choice to study [e.g., prior research reveals Echo Park has more homeless veterans].

If your subject of analysis is a phenomenon. A phenomenon refers to a fact, occurrence, or circumstance that can be studied or observed but with the cause or explanation to be in question. In this sense, a phenomenon that forms your subject of analysis can encompass anything that can be observed or presumed to exist but is not fully understood. In the social and behavioral sciences, the case usually focuses on human interaction within a complex physical, social, economic, cultural, or political system. For example, the phenomenon could be the observation that many vehicles used by ISIS fighters are small trucks with English language advertisements on them. The research problem could be that ISIS fighters are difficult to combat because they are highly mobile. The research questions could be how and by what means are these vehicles used by ISIS being supplied to the militants and how might supply lines to these vehicles be cut? How might knowing the suppliers of these trucks from overseas reveal larger networks of collaborators and financial support? A case study of a phenomenon most often encompasses an in-depth analysis of a cause and effect that is grounded in an interactive relationship between people and their environment in some way.

NOTE:   The choice of the case or set of cases to study cannot appear random. Evidence that supports the method by which you identified and chose your subject of analysis should be linked to the findings from the literature review. Be sure to cite any prior studies that helped you determine that the case you chose was appropriate for investigating the research problem.

IV.  Discussion

The main elements of your discussion section are generally the same as any research paper, but centered around interpreting and drawing conclusions about the key findings from your case study. Note that a general social sciences research paper may contain a separate section to report findings. However, in a paper designed around a case study, it is more common to combine a description of the findings with the discussion about their implications. The objectives of your discussion section should include the following:

Reiterate the Research Problem/State the Major Findings Briefly reiterate the research problem you are investigating and explain why the subject of analysis around which you designed the case study were used. You should then describe the findings revealed from your study of the case using direct, declarative, and succinct proclamation of the study results. Highlight any findings that were unexpected or especially profound.

Explain the Meaning of the Findings and Why They are Important Systematically explain the meaning of your case study findings and why you believe they are important. Begin this part of the section by repeating what you consider to be your most important or surprising finding first, then systematically review each finding. Be sure to thoroughly extrapolate what your analysis of the case can tell the reader about situations or conditions beyond the actual case that was studied while, at the same time, being careful not to misconstrue or conflate a finding that undermines the external validity of your conclusions.

Relate the Findings to Similar Studies No study in the social sciences is so novel or possesses such a restricted focus that it has absolutely no relation to previously published research. The discussion section should relate your case study results to those found in other studies, particularly if questions raised from prior studies served as the motivation for choosing your subject of analysis. This is important because comparing and contrasting the findings of other studies helps to support the overall importance of your results and it highlights how and in what ways your case study design and the subject of analysis differs from prior research about the topic.

Consider Alternative Explanations of the Findings It is important to remember that the purpose of social science research is to discover and not to prove. When writing the discussion section, you should carefully consider all possible explanations for the case study results, rather than just those that fit your hypothesis or prior assumptions and biases. Be alert to what the in-depth analysis of the case may reveal about the research problem, including offering a contrarian perspective to what scholars have stated in prior research.

Acknowledge the Study's Limitations You can state the study's limitations in the conclusion section of your paper but describing the limitations of your subject of analysis in the discussion section provides an opportunity to identify the limitations and explain why they are not significant. This part of the discussion section should also note any unanswered questions or issues your case study could not address. More detailed information about how to document any limitations to your research can be found here .

Suggest Areas for Further Research Although your case study may offer important insights about the research problem, there are likely additional questions related to the problem that remain unanswered or findings that unexpectedly revealed themselves as a result of your in-depth analysis of the case. Be sure that the recommendations for further research are linked to the research problem and that you explain why your recommendations are valid in other contexts and based on the original assumptions of your study.

V.  Conclusion

As with any research paper, you should summarize your conclusion in clear, simple language; emphasize how the findings from your case study differs from or supports prior research and why. Do not simply reiterate the discussion section. Provide a synthesis of key findings presented in the paper to show how these converge to address the research problem. If you haven't already done so in the discussion section, be sure to document the limitations of your case study and needs for further research.

The function of your paper's conclusion is to: 1)  restate the main argument supported by the findings from the analysis of your case; 2) clearly state the context, background, and necessity of pursuing the research problem using a case study design in relation to an issue, controversy, or a gap found from reviewing the literature; and, 3) provide a place for you to persuasively and succinctly restate the significance of your research problem, given that the reader has now been presented with in-depth information about the topic.

Consider the following points to help ensure your conclusion is appropriate:

• If the argument or purpose of your paper is complex, you may need to summarize these points for your reader.
• If prior to your conclusion, you have not yet explained the significance of your findings or if you are proceeding inductively, use the conclusion of your paper to describe your main points and explain their significance.
• Move from a detailed to a general level of consideration of the case study's findings that returns the topic to the context provided by the introduction or within a new context that emerges from your case study findings.

Note that, depending on the discipline you are writing in and your professor's preferences, the concluding paragraph may contain your final reflections on the evidence presented applied to practice or on the essay's central research problem. However, the nature of being introspective about the subject of analysis you have investigated will depend on whether you are explicitly asked to express your observations in this way.

Problems to Avoid

Overgeneralization One of the goals of a case study is to lay a foundation for understanding broader trends and issues applied to similar circumstances. However, be careful when drawing conclusions from your case study. They must be evidence-based and grounded in the results of the study; otherwise, it is merely speculation. Looking at a prior example, it would be incorrect to state that a factor in improving girls access to education in Azerbaijan and the policy implications this may have for improving access in other Muslim nations is due to girls access to social media if there is no documentary evidence from your case study to indicate this. There may be anecdotal evidence that retention rates were better for girls who were on social media, but this observation would only point to the need for further research and would not be a definitive finding if this was not a part of your original research agenda.

Failure to Document Limitations No case is going to reveal all that needs to be understood about a research problem. Therefore, just as you have to clearly state the limitations of a general research study , you must describe the specific limitations inherent in the subject of analysis. For example, the case of studying how women conceptualize the need for water conservation in a village in Uganda could have limited application in other cultural contexts or in areas where fresh water from rivers or lakes is plentiful and, therefore, conservation is understood differently than preserving access to a scarce resource.

Failure to Extrapolate All Possible Implications Just as you don't want to over-generalize from your case study findings, you also have to be thorough in the consideration of all possible outcomes or recommendations derived from your findings. If you do not, your reader may question the validity of your analysis, particularly if you failed to document an obvious outcome from your case study research. For example, in the case of studying the accident at the railroad crossing to evaluate where and what types of warning signals should be located, you failed to take into consideration speed limit signage as well as warning signals. When designing your case study, be sure you have thoroughly addressed all aspects of the problem and do not leave gaps in your analysis.

Writing Tip

At Least Five Misconceptions about Case Study Research

Social science case studies are often perceived as limited in their ability to create new knowledge because they are not randomly selected and findings cannot be generalized to larger populations. Flyvbjerg examines five misunderstandings about case study research and systematically "corrects" each one. To quote, these are:

Misunderstanding 1 :  General, theoretical [context-independent knowledge is more valuable than concrete, practical (context-dependent) knowledge. Misunderstanding 2 :  One cannot generalize on the basis of an individual case; therefore, the case study cannot contribute to scientific development. Misunderstanding 3 :  The case study is most useful for generating hypotheses; that is, in the first stage of a total research process, whereas other methods are more suitable for hypotheses testing and theory building. Misunderstanding 4 :  The case study contains a bias toward verification, that is, a tendency to confirm the researcher’s preconceived notions. Misunderstanding 5 :  It is often difficult to summarize and develop general propositions and theories on the basis of specific case studies [p. 221].

While writing your paper, think introspectively about how you addressed these misconceptions because to do so can help you strengthen the validity and reliability of your research by clarifying issues of case selection, the testing and challenging of existing assumptions, the interpretation of key findings, and the summation of case outcomes. Think of a case study research paper as a complete, in-depth narrative about the specific properties and key characteristics of your subject of analysis applied to the research problem.

Executive Summary vs. Summary

What's the difference.

An executive summary and a summary are both concise versions of a longer document or report, but they serve different purposes. An executive summary is typically written for high-level executives or decision-makers who may not have the time or inclination to read the entire document. It provides a brief overview of the main points, findings, and recommendations, allowing the reader to quickly grasp the key information. On the other hand, a summary is a condensed version of the entire document, aimed at providing a comprehensive understanding of the main ideas and supporting details. It is usually written for a broader audience and includes more specific information than an executive summary. While both serve to provide a condensed version of a longer text, the executive summary is more focused on providing a snapshot of the most important information, while the summary aims to capture the essence of the entire document.

Further Detail

Introduction.

When it comes to summarizing information, two commonly used terms are Executive Summary and Summary. While both serve the purpose of providing a condensed version of a longer document or report, they have distinct attributes that set them apart. In this article, we will explore the key differences and similarities between Executive Summary and Summary, highlighting their unique characteristics and purposes.

Definition and Purpose

An Executive Summary is a concise overview of a larger document, typically written for business or executive-level readers. It aims to provide a high-level understanding of the main points, findings, and recommendations of the document, allowing busy executives to grasp the key information quickly. On the other hand, a Summary is a condensed version of any written material, such as an article, book, or research paper. It serves the purpose of providing a brief overview of the main ideas and arguments presented in the original text.

Length and Detail

One of the primary differences between an Executive Summary and a Summary lies in their length and level of detail. An Executive Summary is typically longer and more detailed than a Summary. It may range from one to several pages, depending on the complexity of the document it summarizes. In contrast, a Summary is usually much shorter, often limited to a few paragraphs or a single page. Due to its brevity, a Summary may not include all the nuances and intricacies of the original text, focusing instead on the main points.

Audience and Context

The intended audience and context also play a significant role in distinguishing an Executive Summary from a Summary. An Executive Summary is specifically tailored for busy executives, stakeholders, or decision-makers who need a quick understanding of the document's content without delving into the details. It is commonly used in business settings, board meetings, or when seeking funding or approval for a project. On the other hand, a Summary can have a broader audience, including students, researchers, or general readers who want a brief overview of a particular topic or text.

Content and Structure

While both Executive Summary and Summary provide condensed versions of a document, their content and structure may differ. An Executive Summary typically includes sections such as an introduction, background information, methodology, findings, conclusions, and recommendations. It aims to provide a comprehensive overview of the entire document, allowing readers to understand the context, process, and outcomes. In contrast, a Summary may focus more on the main ideas, arguments, and evidence presented in the original text, omitting sections like methodology or background information that are not directly relevant to the core content.

Language and Style

The language and style used in an Executive Summary and a Summary can also vary. An Executive Summary often adopts a formal and professional tone, using business terminology and concise language to convey the key points effectively. It may include charts, graphs, or visual aids to enhance understanding. On the other hand, a Summary can be written in a more accessible and reader-friendly style, using simpler language and avoiding technical jargon. It aims to present the main ideas in a clear and straightforward manner, ensuring that readers can grasp the essence of the original text without getting overwhelmed by complex terminology.

Executive Summaries and Summaries are utilized in various contexts and serve different purposes. An Executive Summary is commonly used in business and corporate settings, where time is limited, and decision-makers need a concise overview of a document's content to make informed choices. It is often included at the beginning of business plans, project proposals, or research reports. On the other hand, Summaries are widely used in academic and educational settings, where students or researchers need to quickly understand the main ideas of a text before deciding whether to explore it further. They are also useful for general readers who want a brief overview of a book, article, or news story.

In summary, while both Executive Summary and Summary serve the purpose of providing condensed versions of longer documents, they have distinct attributes that set them apart. An Executive Summary is typically longer, more detailed, and tailored for busy executives, focusing on the main points, findings, and recommendations of a document. On the other hand, a Summary is shorter, more accessible, and can have a broader audience, aiming to provide a brief overview of the main ideas and arguments presented in the original text. Understanding the differences between these two types of summaries allows us to effectively communicate information to the intended audience and context.

Abstract vs Executive Summary: What Are the Differences?

by  Antony W

July 7, 2022

An abstract and an executive summary may play the same role in writing, but there are differences between them that you need to understand. Ideally, both play the role of providing a summarized version of a study to give readers an overview of a whole project. But they differ in length, structure, and overall purpose.

In this abstract vs executive summary guide, you’ll learn of the similarities and the differences between the two, so you have a clear picture of what they are and the role they play in writing.

While an executive summary and an abstract present the significance of a project in a shorter form, they both have distinct level of details. An abstract condenses a document in a few words. An executive summary, on the other hand, is a standalone version of a thesis.

With that said, let’s get started. 

Abstract vs Executive Summary: Learn The Differences

The following is an abstract vs executive summary teardown to help you understand the similarities and differences between the two concepts:

What is an Abstract?

An abstract is a summary of an overview of a research project important points and findings. An abstract is the first part of a research that people read, so you need to make sure you provide comprehensive and engaging information to keep them hooked.

Your abstract should:

• Include the core problem, the precise aim or target, and, if applicable, the extent of the project.
• Feature a clear description of the manner in which you carried out your research. In this respect, the section should feature the test procedures used, and the means by which you carried out the research. 
• Highlight what you discovered, as well as the conclusions, suggestions, and conclusion

Despite the fact that the abstract is the initial section of your paper, we strongly recommend that you write it one you’ve worked on the other parts of the paper.

The abstract should be 150 to 300 words long, stand on its own as a summary of your whole article, and it should be clear to someone who hasn’t read your paper or any relevant materials in your work.

The abstract should be on its own page (NOT as a standalone project), following the title page and acknowledgments but before the table of contents.

What Types of Abstracts Are There? 

There are two types of abstracts:  

• Humanities abstract
• Scientific abstract

Abstracts in the Humanities   

The purpose of a humanity abstract is to give a quick summary of the paper’s content. When writing an abstract in the humanities, it’s crucial that the abstract matches the paper’s arrangement. Also, make sure you write it in the third person present tense.

Abstracts in Scientific Papers

The objective of a scientific abstract is to tell the reader about the procedure and purpose of an experiment. You should write this type of an abstract in past tense passive voice.

What is an Executive Summary?

An executive summary is a brief document that condenses a lengthy report or proposal so that readers may quickly get familiar with a great amount of information without having to read it all.

It generally includes a brief explanation of the issue or proposition addressed in the primary document(s), background information, a succinct analysis, and key findings. The primary aim of an abstract is to make it easy for managers to make better decisions.

Executive summaries should be as brief as feasible. Your audience is pressed for time and attention, and they want to learn as much as possible about your company strategy in the shortest time. Keep your executive summary as short as two page, although you can make it longer if you have important information to share.

What Information Should an Executive Summary Include?

If your teacher has asked you to write a business plan, make sure the executive summary section includes the most important information about the proposed business. Here are some ideas:

1. Product Description & the Problem the Business Can Solve

Include a concise explanation of the product or service you’re selling, as well as why it’s important. Your company doesn’t have to solve a bigger societal issue, but it should meet a consumer need or a market opportunity.

2. A Definition and Explanation of Your Target Market

Your target market is people you believe will be your clients. The product name alone may be sufficient to define your target market. But if it doesn’t, a quick explanation of your target market—your major audience or the individuals you believe would be willing to pay for your solution—can suffice.

3. A Complete Overview of Finances

If you already have a business, this might be as easy as showcasing current yearly sales and growth in the previous year. It might be a quick summary of ambitions for a startup, such as a sales prediction aim for the following year. A basic highlights chart, a bar chart displaying revenue and gross margin over the next three years is something you should include in the executive summary section of your document. 

4. Business Competition

Assuming that your firm will face competition (and it will), discuss how your company will set itself apart. Are you in a pricing war, a quality war, or something else entirely? Make your description as concise as possible, and remember to keep it short.

5. The People in Your Business (Or Your Team)

This is especially critical for new businesses. Investors want to know who is behind the company’s concept and why you and your team are the best individuals to run it. It’s also a good idea to point out any weaknesses in your team – and how you plan to fill them. If you have any possible partners or candidates in mind, list them briefly in your comprehensive business plan and expound on their qualities.

Final Thoughts

Both an abstract and an executive summary are important because they present a condensed version of a research and business document respectively.

However, the executive summary tends to be longer than the abstract. Also, an executive summary has a limited audience, often focusing strictly on matter to do with business and related transactions.

A literature review surveys scholarly articles, books and other sources relevant to a particular issue, area of research, or theory, and by so doing, providing a description, summary, and critical evaluation of these works. Literature reviews are designed to provide an overview of sources you have explored while researching a particular topic and to demonstrate to your readers how your research fits into the larger field of study.

Importance of a Good Literature Review

A literature review may consist of simple a summary of key sources, but it usually has an organizational pattern and combines both summary and synthesis, often within specific conceptual categories . A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are planning to investigate a research problem. The analytical features of a literature review might:

• Give a new interpretation of old material or combine new with old interpretations,
• Trace the intellectual progression of the field, including major debates,
• Depending on the situation, evaluate the sources and advise the reader on the most pertinent or relevant, or
• Usually in the conclusion of a literature review, identify where gaps exist in how a problem has been researched to date.

The purpose of a literature review is to:

• Place each work in the context of its contribution to the understanding of the research problem being studied,
• Describe the relationship of each work to the others under consideration,
• Identify new ways to interpret, and shed light on any gaps in previous research,
• Resolve conflicts amongst seemingly contradictory previous studies,
• Identify areas of prior scholarship to prevent duplication of effort,
• Point the way in fulfilling a need for additional research, and
• Locate your own research within the context of existing literature.

Los Angeles, CA: SAGE, 2012.

Types of Literature Reviews

It is important to think of knowledge in a given field as consisting of three layers.* First, there are the primary studies that researchers conduct and publish. Second are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the original studies. Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally that become part of the lore of field. In composing a literature review, it is important to note that it is often this third layer of knowledge that is cited as "true" even though it often has only a loose relationship to the primary studies and secondary literature reviews. Given this, while literature reviews are designed to provide an overview and synthesis of pertinent sources you have explored, there are a number of approaches you could adopt depending upon the type of analysis underpinning your study.

Argumentative Review This form examines literature selectively in order to support or refute an argument, deeply imbedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint. Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse. However, note that they can also introduce problems of bias when they are used to to make summary claims of the sort found in systematic reviews.

Integrative Review Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated. The body of literature includes all studies that address related or identical hypotheses. A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication.

Historical Review Few things rest in isolation from historical precedent. Historical reviews are focused on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomena emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.

Methodological Review A review does not always focus on what someone said [content], but how they said it [method of analysis]. This approach provides a framework of understanding at different levels (i.e. those of theory, substantive fields, research approaches and data collection and analysis techniques), enables researchers to draw on a wide variety of knowledge ranging from the conceptual level to practical documents for use in fieldwork in the areas of ontological and epistemological consideration, quantitative and qualitative integration, sampling, interviewing, data collection and data analysis, and helps highlight many ethical issues which we should be aware of and consider as we go through our study.

Systematic Review This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research, and to collect, report, and analyse data from the studies that are included in the review. Typically it focuses on a very specific empirical question, often posed in a cause-and-effect form, such as "To what extent does A contribute to B?"

Theoretical Review The purpose of this form is to concretely examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomena. The theoretical literature review help establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. The unit of analysis can focus on a theoretical concept or a whole theory or framework.

Structure and Writing Style

I.  Thinking About Your Literature Review

The structure of a literature review should include the following :

• An overview of the subject, issue or theory under consideration, along with the objectives of the literature review,
• Division of works under review into themes or categories (e.g. works that support of a particular position, those against, and those offering alternative approaches entirely),
• An explanation of how each work is similar to and how it varies from the others,
• Conclusions as to which pieces are best considered in their argument, are most convincing of their opinions, and make the greatest contribution to the understanding and development of their area of research

The critical evaluation of each work should consider :

• Provenance -- what are the author's credentials? Are the author's arguments supported by evidence (e.g. primary historical material, case studies, narratives, statistics, recent scientific findings)?
• Objectivity -- is the author's perspective even-handed or prejudicial? Is contrary data considered or is certain pertinent information ignored to prove the author's point?
• Persuasiveness -- which of the author's theses are most/least convincing?
• Value -- are the author's arguments and conclusions convincing? Does the work ultimately contribute in any significant way to an understanding of the subject?

II.  Development of the Literature Review

Four Stages

• Problem formulation -- which topic or field is being examined and what are its component issues?
• Literature search -- finding materials relevant to the subject being explored.
• Data evaluation -- determining which literature makes a significant contribution to the understanding of the topic.
• Analysis and interpretation -- discussing the findings and conclusions of pertinent literature.

Consider the following issues before writing the literature review: Clarify If your assignment is not very specific about what form your literature review should take, seek clarification from your professor by asking these questions:

• Roughly how many sources should I include?
• What types of sources should I review (books, journal articles, websites)?
• Should I summarize, synthesize, or critique your sources by discussing a common theme or issue?
• Should I evaluate the sources?
• Should I provide subheadings and other background information, such as definitions and/or a history?

Find Models Use the exercise of reviewing the literature to examine how authors in your discipline or area of interest have composed their literature reviews. Read them to get a sense of the types of themes you might want to look for in your own research or ways to organize your final review. The bibliography or reference section of sources you've already read are also excellent entry points into your own research. Narrow the Topic The narrower your topic, the easier it will be to limit the number of sources you need to read in order to obtain a good survey of relevant resources. Your professor will probably not expect you to read everything that's available about the topic, but you'll make your job easier if you first limit scope of the research problem. A good strategy is to begin by searching the HOMER catalog for books about the topic and review their contents for chapters that focus on more specific issues. You can also review the subject indexes of books to find references to specific issues that can serve as the focus of your research. For example, a book surveying the history of the Israeli-Palestinian conflict may include a chapter on the role Egypt has played in mediating the conflict. Consider Whether Your Sources are Current Some disciplines require that you use information that is as current as possible. This is very common in the sciences where research conducted only two years ago could be obsolete. However, when writing a review in the social sciences, a survey of the history of the literature may be what is needed because what is important is how perspectives have changed over the years or within a certain time period. Try sorting through some other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to consider what is consider by scholars to be a "hot topic" and what is not.

III.  Ways to Organize Your Literature Review

Chronological of Events If your review follows the chronological method, you could write about the materials according to when they were published. This approach should only be followed if a clear path of research building on previous research can be identified and that these trends follow a clear chronological order of development. For example, a literature review that focuses on continuing research about the emergence of German economic power after the fall of the Soviet Union. By Publication Order your sources by publication chronology, then, only if the order demonstrates a more important trend. For instance, you could order a review of literature on environmental studies of brown fields if the progression revealed, for example, a change in the soil collection practices of the researchers who wrote and/or conducted the studies. Thematic (“conceptual categories”) Thematic reviews of literature are organized around a topic or issue, rather than the progression of time. However, progression of time may still be an important factor in a thematic review. For example, a review of the Internet’s impact on American presidential politics could focus on the development of online political satire. While the study focuses on one topic, the Internet’s impact on American presidential politics, it will still be organized chronologically reflecting technological developments in media. The only difference here between a "chronological" and a "thematic" approach is what is emphasized the most: the role of the Internet in presidential politics. Note however that more authentic thematic reviews tend to break away from chronological order. A review organized in this manner would shift between time periods within each section according to the point made. Methodological A methodological approach focuses on the methods utilized by the researcher. For the Internet in American presidential politics project, one methodological approach would be to look at cultural differences between the portrayal of American presidents on American, British, and French websites. Or the review might focus on the fundraising impact of the Internet on a particular political party. A methodological scope will influence either the types of documents in the review or the way in which these documents are discussed.

Other Sections of Your Literature Review Once you've decided on the organizational method for your literature review, the sections you need to include in the paper should be easy to figure out because they arise from your organizational strategy. In other words, a chronological review would have subsections for each vital time period; a thematic review would have subtopics based upon factors that relate to the theme or issue. However, sometimes you may need to add additional sections that are necessary for your study, but do not fit in the organizational strategy of the body. What other sections you include in the body is up to you but include only what is necessary for the reader to locate your study within the larger scholarship framework.

Here are examples of other sections you may need to include depending on the type of review you write:

• Current Situation : information necessary to understand the topic or focus of the literature review.
• History : the chronological progression of the field, the literature, or an idea that is necessary to understand the literature review, if the body of the literature review is not already a chronology.
• Selection Methods : the criteria you used to select (and perhaps exclude) sources in your literature review. For instance, you might explain that your review includes only peer-reviewed articles and journals.
• Standards : the way in which you present your information.
• Questions for Further Research : What questions about the field has the review sparked? How will you further your research as a result of the review?

IV.  Writing Your Literature Review

Once you've settled on how to organize your literature review, you're ready to write each section. When writing your review, keep in mind these issues.

Use Evidence A literature review in this sense is just like any other academic research paper. Your interpretation of the available sources must be backed up with evidence to show that what you are saying is valid. Be Selective Select only the most important points in each source to highlight in the review. The type of information you choose to mention should relate directly to the research problem, whether it is thematic, methodological, or chronological. Use Quotes Sparingly Some short quotes are okay if you want to emphasize a point, or if what the author said just cannot be rewritten in your own words. Sometimes you may need to quote certain terms that were coined by the author, not common knowledge, or taken directly from the study. Do not use extensive quotes as a substitute your own summary and interpretation of the literature. Summarize and Synthesize Remember to summarize and synthesize your sources within each paragraph as well as throughout the review. Recapitulate important features of a research study, but then synthesize it by rephrasing the study's significance and relating it to their own work. Keep Your Own Voice While the literature review presents others' ideas, your voice (the writer's) should remain front and center. For example, weave references to other sources into what you are writing but maintain your own voice by starting and ending the paragraph with your own ideas and wording. Use Caution When Paraphrasing When paraphrasing a source that is not your own, be sure to represent the author's information or opinions accurately and in your own words. Even when paraphrasing an author’s work, you still must provide a citation to that work.

V.  Common Mistakes to Avoid

These are the most common mistakes made in reviewing social science research literature.

• Sources in your literature review do not clearly relate to the research problem;
• You do not take sufficient time to define and identify the most relevent sources to use in the literature review related to the research problem;
• Relies exclusively on secondary analytical sources rather than including relevant primary research studies or data;
• Uncritically accepts another researcher's findings and interpretations as valid, rather than examining critically all aspects of the research design and analysis;
• Does not describe the search procedures that were used in the literature review;
• Reports isolated statistical results rather than synthesizing them in chi-squared or meta-analytic methods; and,
• Only includes research that validates assumptions and does not consider contrary findings and alternative interpretations found in the literature.

Writing Tip

Break Out of Your Disciplinary Box!

Thinking in an interdisciplinary way about a research problem can be a rewarding exercise in applying new ideas, theories, or concepts to an old problem. For example, what might cultural anthropologists say about the continuing conflict in the Middle East? In what ways might geographers view the need for better distribution of social service agencies in large cities than how social workers might study the issue? You don’t want to substitute a thorough review of core research literature in your discipline for studies conducted in other fields of study. However, particularly in the social sciences, thinking about research problems from multiple vectors is a key strategy for finding new solutions. Consult with a librarian about identifying research databases in other disciplines; almost every field of study has at least one comprehensive database devoted to indexing its research literature.

Another Writing Tip

Don't Just Review for Content!

While conducting a review of the literature, maximize the time you devote to writing this part of your paper by thinking broadly about what you should be looking for and evaluating. Review not just what scholars are saying, but how are they saying it. Some questions to ask:

• How are they organizing their ideas?
• What methods have they used to study the problem?
• What theories have been used to explain, predict, or understand their research problem?
• What sources have they cited to support of their conclusions?
• How have they used non-textual elements [e.g., charts, graphs, figures, etc.] to illustrate key points?

When you begin to write your literature review section, you'll be glad you dug deeper into how the research was constructed because it lays a foundation for  developing more substantial analysis and interpretation of the research problem.

Yet Another Writing Tip

When Do I Know I Can Stop Looking and Move On?

Here are several strategies you can utilize to assess whether you've adequately reviewed the literature:

• Look for repeating patterns in the research findings. If the same thing is being said, just by different people, then this likely demonstrates that the research problem has hit a conceptual dead end. At this point consider: Does your study extend current research?  Does it forge a new path? Or, does is merely add more of the same thing being said?
• Look at sources the authors cite to in their work. If you begin to see the same researchers cited again and again, then this is often an indication that no new ideas have been introduced in addressing the research question.
• Search Google Scholar to identify who has subsequently cited leading scholars already identified in your literature review. This is called citation tracking and there are a number of sources that can help you identify who has cited whom, particularly scholars from outside of your discipline. If the same authors are being cited again and again, this may indicate no new literature has been written on the topic.

How to write an executive summary, with examples

The best way to do that is with an executive summary. If you’ve never written an executive summary, this article has all you need to know to plan, write, and share them with your team.

What is an executive summary?

An executive summary is an overview of a document. The length and scope of your executive summary will differ depending on the document it’s summarizing, but in general an executive summary can be anywhere from one to two pages long. In the document, you’ll want to share all of the information your readers and important stakeholders need to know.

Imagine it this way: if your high-level stakeholders were to only read your executive summary, would they have all of the information they need to succeed? If so, your summary has done its job.

You’ll often find executive summaries of:

Business cases

Project proposals

Research documents

Environmental studies

Market surveys

In general, there are four parts to any executive summary:

Start with the problem or need the document is solving.

Outline the recommended solution.

Explain the solution’s value.

Wrap up with a conclusion about the importance of the work.

What is an executive summary in project management?

In project management, an executive summary is a way to bring clarity to cross-functional collaborators, team leadership, and project stakeholders . Think of it like a project’s “ elevator pitch ” for team members who don’t have the time or the need to dive into all of the project’s details.

The main difference between an executive summary in project management and a more traditional executive summary in a business plan is that the former should be created at the beginning of your project—whereas the latter should be created after you’ve written your business plan. For example, to write an executive summary of an environmental study, you would compile a report on the results and findings once your study was over. But for an executive summary in project management, you want to cover what the project is aiming to achieve and why those goals matter.

The same four parts apply to an executive summary in project management:

Start with the problem or need the project is solving.  Why is this project happening? What insight, customer feedback, product plan, or other need caused it to come to life?

Outline the recommended solution, or the project’s objectives.  How is the project going to solve the problem you established in the first part? What are the project goals and objectives?

Explain the solution’s value.  Once you’ve finished your project, what will happen? How will this improve and solve the problem you established in the first part?

Wrap up with a conclusion about the importance of the work.  This is another opportunity to reiterate why the problem is important, and why the project matters. It can also be helpful to reference your audience and how your solution will solve their problem. Finally, include any relevant next steps.

If you’ve never written an executive summary before, you might be curious about where it fits into other project management elements. Here’s how executive summaries stack up:

Executive summary vs. project plan

A  project plan  is a blueprint of the key elements your project will accomplish in order to hit your project goals and objectives. Project plans will include your goals, success metrics, stakeholders and roles, budget, milestones and deliverables, timeline and schedule, and communication plan .

An executive summary is a summary of the most important information in your project plan. Think of the absolutely crucial things your management team needs to know when they land in your project, before they even have a chance to look at the project plan—that’s your executive summary.

Executive summary vs. project overview

Project overviews and executive summaries often have similar elements—they both contain a summary of important project information. However, your project overview should be directly attached to your project. There should be a direct line of sight between your project and your project overview.

While you can include your executive summary in your project depending on what type of  project management tool  you use, it may also be a stand-alone document.

Executive summary vs. project objectives

Your executive summary should contain and expand upon your  project objectives  in the second part ( Outline the recommended solution, or the project’s objectives ). In addition to including your project objectives, your executive summary should also include why achieving your project objectives will add value, as well as provide details about how you’re going to get there.

The benefits of an executive summary

You may be asking: why should I write an executive summary for my project? Isn’t the project plan enough?

Well, like we mentioned earlier, not everyone has the time or need to dive into your project and see, from a glance, what the goals are and why they matter.  Work management tools  like Asana help you capture a lot of crucial information about a project, so you and your team have clarity on who’s doing what by when. Your executive summary is designed less for team members who are actively working on the project and more for stakeholders outside of the project who want quick insight and answers about why your project matters.

An effective executive summary gives stakeholders a big-picture view of the entire project and its important points—without requiring them to dive into all the details. Then, if they want more information, they can access the project plan or navigate through tasks in your work management tool.

How to write a great executive summary, with examples

Every executive summary has four parts. In order to write a great executive summary, follow this template. Then once you’ve written your executive summary, read it again to make sure it includes all of the key information your stakeholders need to know.

1. Start with the problem or need the project is solving

At the beginning of your executive summary, start by explaining why this document (and the project it represents) matter. Take some time to outline what the problem is, including any research or customer feedback you’ve gotten . Clarify how this problem is important and relevant to your customers, and why solving it matters.

For example, let’s imagine you work for a watch manufacturing company. Your project is to devise a simpler, cheaper watch that still appeals to luxury buyers while also targeting a new bracket of customers.

Example executive summary:

In recent customer feedback sessions, 52% of customers have expressed a need for a simpler and cheaper version of our product. In surveys of customers who have chosen competitor watches, price is mentioned 87% of the time. To best serve our existing customers, and to branch into new markets, we need to develop a series of watches that we can sell at an appropriate price point for this market.

2. Outline the recommended solution, or the project’s objectives

Now that you’ve outlined the problem, explain what your solution is. Unlike an abstract or outline, you should be  prescriptive  in your solution—that is to say, you should work to convince your readers that your solution is the right one. This is less of a brainstorming section and more of a place to support your recommended solution.

Because you’re creating your executive summary at the beginning of your project, it’s ok if you don’t have all of your deliverables and milestones mapped out. But this is your chance to describe, in broad strokes, what will happen during the project. If you need help formulating a high-level overview of your project’s main deliverables and timeline, consider creating a  project roadmap  before diving into your executive summary.

Continuing our example executive summary:

Our new watch series will begin at 20% cheaper than our current cheapest option, with the potential for 40%+ cheaper options depending on material and movement. In order to offer these prices, we will do the following:

Offer watches in new materials, including potentially silicone or wood

Use high-quality quartz movement instead of in-house automatic movement

Introduce customizable band options, with a focus on choice and flexibility over traditional luxury

Note that every watch will still be rigorously quality controlled in order to maintain the same world-class speed and precision of our current offerings.

3. Explain the solution’s value

At this point, you begin to get into more details about how your solution will impact and improve upon the problem you outlined in the beginning. What, if any, results do you expect? This is the section to include any relevant financial information, project risks, or potential benefits. You should also relate this project back to your company goals or  OKRs . How does this work map to your company objectives?

With new offerings that are between 20% and 40% cheaper than our current cheapest option, we expect to be able to break into the casual watch market, while still supporting our luxury brand. That will help us hit FY22’s Objective 3: Expanding the brand. These new offerings have the potential to bring in upwards of three million dollars in profits annually, which will help us hit FY22’s Objective 1: 7 million dollars in annual profit.

Early customer feedback sessions indicate that cheaper options will not impact the value or prestige of the luxury brand, though this is a risk that should be factored in during design. In order to mitigate that risk, the product marketing team will begin working on their go-to-market strategy six months before the launch.

4. Wrap up with a conclusion about the importance of the work

Now that you’ve shared all of this important information with executive stakeholders, this final section is your chance to guide their understanding of the impact and importance of this work on the organization. What, if anything, should they take away from your executive summary?

To round out our example executive summary:

Cheaper and varied offerings not only allow us to break into a new market—it will also expand our brand in a positive way. With the attention from these new offerings, plus the anticipated demand for cheaper watches, we expect to increase market share by 2% annually. For more information, read our  go-to-market strategy  and  customer feedback documentation .

Example of an executive summary

When you put it all together, this is what your executive summary might look like:

Common mistakes people make when writing executive summaries

You’re not going to become an executive summary-writing pro overnight, and that’s ok. As you get started, use the four-part template provided in this article as a guide. Then, as you continue to hone your executive summary writing skills, here are a few common pitfalls to avoid:

Avoid using jargon

Your executive summary is a document that anyone, from project contributors to executive stakeholders, should be able to read and understand. Remember that you’re much closer to the daily work and individual tasks than your stakeholders will be, so read your executive summary once over to make sure there’s no unnecessary jargon. Where you can, explain the jargon, or skip it all together.

Remember: this isn’t a full report

Your executive summary is just that—a summary. If you find yourself getting into the details of specific tasks, due dates, and attachments, try taking a step back and asking yourself if that information really belongs in your executive summary. Some details are important—you want your summary to be actionable and engaging. But keep in mind that the wealth of information in your project will be captured in your  work management tool , not your executive summary.

Make sure the summary can stand alone

You know this project inside and out, but your stakeholders won’t. Once you’ve written your executive summary, take a second look to make sure the summary can stand on its own. Is there any context your stakeholders need in order to understand the summary? If so, weave it into your executive summary, or consider linking out to it as additional information.

Always proofread

Your executive summary is a living document, and if you miss a typo you can always go back in and fix it. But it never hurts to proofread or send to a colleague for a fresh set of eyes.

In summary: an executive summary is a must-have

Executive summaries are a great way to get everyone up to date and on the same page about your project. If you have a lot of project stakeholders who need quick insight into what the project is solving and why it matters, an executive summary is the perfect way to give them the information they need.

Review vs Summary: Difference and Comparison

A Review is a report highlighting someone’s opinion about something, its ideas, the theme, and how it affects someone or something.

Key Takeaways A review evaluates or critiques a work or product, providing opinions and insights on its quality, effectiveness, or value. At the same time, a summary is a condensed version of a work presenting its main points or ideas without offering personal opinions or judgments. Reviews include personal assessments, recommendations, and comparisons to similar works or products. In contrast, summaries focus on accurately conveying the core content or message of the original work without inserting personal opinions. Both reviews and summaries can be useful for understanding the content or value of a work. Still, they serve different purposes: reviews inform potential consumers or readers about the quality of work, while summaries provide a quick and concise understanding of the original content.

Review vs Summary

The difference between Review and a Summary is that Review reflects what the partaker thinks about the narrative in all aspects. In contrast, a Summary is just a shortened or condensed version of an artefact that gives the gist of the whole body.

Review can also mean a revision or subsequent reading of a text or narrative. Whereas, Summary is a broad term which refers to the short restatement reflecting the critical points of any piece of literature, argument or lecture.

Comparison Table

What is review.

A review delineates the partaker’s opinion about the presented subject. It doesn’t require the exact points of the narrative but revolves around the ideas of it and the way it was presented.

This is used in formal and informal contexts like “a movie review” or “review of a research paper” and can be applied to any subject that can be presented to an audience.

There will exist no final review as every individual contemplates the subject differently. However, the study can be generalized as good or bad.

These reviews don’t necessarily account for the reviewer’s opinions and are closely related to a summary. However, unlike resumes, these reviews don’t have to highlight all the subject’s main points in the same order.

This review is not presented to an audience but is for the use of the partaker himself. The need for this kind of review arises when the partaker needs to demonstrate their knowledge on the subject, like examinations.

What is Summary?

A Summary is the concise report of any presented rendering or narrative used for a better and easier understanding. It covers all the text’s main points and gives the story’s essence in the exact order as the report does.

A summary sticks to the points of the subject and doesn’t deviate from them at all. It does not include the summarizer’s opinions or acknowledge any assessment of the issue.

Absoluteness is the backbone of a summary. Since the resume needs to hold on to the exact points of the subject, the summaries from different summarizers must be clear.

Summaries always proceed in the exact nature of the subject, starting from the introduction and terminating where the issue ends.

It is mainly used in academic contexts and for other narratives.

Main Differences Between Review and Summary

• A review revolves around the general idea of the subject, whereas a summary holds onto the exact points of the subject.
• The opinion of the partaker is an integral part of a review, whereas it doesn’t hold any significance in the case of a review.
