Team Building Exercises – Problem Solving and Decision Making

Fun ways to turn problems into opportunities.

By the Mind Tools Content Team

Whether there's a complex project looming or your team members just want to get better at dealing with day-to-day issues, your people can achieve much more when they solve problems and make decisions together.

By developing their problem-solving skills, you can improve their ability to get to the bottom of complex situations. And by refining their decision-making skills, you can help them work together maturely, use different thinking styles, and commit collectively to decisions.

In this article, we'll look at three team-building exercises that you can use to improve problem solving and decision making in a new or established team.

Exercises to Build Decision-Making and Problem-Solving Skills

Use the following exercises to help your team members solve problems and make decisions together more effectively.

Exercise 1: Lost at Sea*

In this activity, participants must pretend that they've been shipwrecked and are stranded in a lifeboat. Each team has a box of matches, and a number of items that they've salvaged from the sinking ship. Members must agree which items are most important for their survival.

Download and print our team-building exercises worksheet to help you with this exercise.

This activity builds problem-solving skills as team members analyze information, negotiate and cooperate with one another. It also encourages them to listen and to think about the way they make decisions.

What You'll Need

• Up to five people in each group.
• A large, private room.
• A "lost at sea" ranking chart for each team member. This should comprise six columns. The first simply lists each item (see below). The second is empty so that each team member can rank the items. The third is for group rankings. The fourth is for the "correct" rankings, which are revealed at the end of the exercise. And the fifth and sixth are for the team to enter the difference between their individual and correct score, and the team and correct rankings, respectively.
• The items to be ranked are: a mosquito net, a can of petrol, a water container, a shaving mirror, a sextant, emergency rations, a sea chart, a floating seat or cushion, a rope, some chocolate bars, a waterproof sheet, a fishing rod, shark repellent, a bottle of rum, and a VHF radio. These can be listed in the ranking chart or displayed on a whiteboard, or both.
• The experience can be made more fun by having some lost-at-sea props in the room.

Flexible, but normally between 25 and 40 minutes.

Instructions

• Divide participants into their teams, and provide everyone with a ranking sheet.
• Ask team members to take 10 minutes on their own to rank the items in order of importance. They should do this in the second column of their sheet.
• Give the teams a further 10 minutes to confer and decide on their group rankings. Once agreed, they should list them in the third column of their sheets.
• Ask each group to compare their individual rankings with their collective ones, and consider why any scores differ. Did anyone change their mind about their own rankings during the team discussions? How much were people influenced by the group conversation?
• Now read out the "correct" order, collated by the experts at the US Coast Guard (from most to least important): - Shaving mirror. (One of your most powerful tools, because you can use it to signal your location by reflecting the sun.) - Can of petrol. (Again, potentially vital for signaling as petrol floats on water and can be lit by your matches.) - Water container. (Essential for collecting water to restore your lost fluids.) -Emergency rations. (Valuable for basic food intake.) - Plastic sheet. (Could be used for shelter, or to collect rainwater.) -Chocolate bars. (A handy food supply.) - Fishing rod. (Potentially useful, but there is no guarantee that you're able to catch fish. Could also feasibly double as a tent pole.) - Rope. (Handy for tying equipment together, but not necessarily vital for survival.) - Floating seat or cushion. (Useful as a life preserver.) - Shark repellent. (Potentially important when in the water.) - Bottle of rum. (Could be useful as an antiseptic for treating injuries, but will only dehydrate you if you drink it.) - Radio. (Chances are that you're out of range of any signal, anyway.) - Sea chart. (Worthless without navigational equipment.) - Mosquito net. (Assuming that you've been shipwrecked in the Atlantic, where there are no mosquitoes, this is pretty much useless.) - Sextant. (Impractical without relevant tables or a chronometer.)

Advice for the Facilitator

The ideal scenario is for teams to arrive at a consensus decision where everyone's opinion is heard. However, that doesn't always happen naturally: assertive people tend to get the most attention. Less forthright team members can often feel intimidated and don't always speak up, particularly when their ideas are different from the popular view. Where discussions are one-sided, draw quieter people in so that everyone is involved, but explain why you're doing this, so that people learn from it.

You can use the Stepladder Technique when team discussion is unbalanced. Here, ask each team member to think about the problem individually and, one at a time, introduce new ideas to an appointed group leader – without knowing what ideas have already been discussed. After the first two people present their ideas, they discuss them together. Then the leader adds a third person, who presents his or her ideas before hearing the previous input. This cycle of presentation and discussion continues until the whole team has had a chance to voice their opinions.

After everyone has finished the exercise, invite your teams to evaluate the process to draw out their experiences. For example, ask them what the main differences between individual, team and official rankings were, and why. This will provoke discussion about how teams arrive at decisions, which will make people think about the skills they must use in future team scenarios, such as listening , negotiating and decision-making skills, as well as creativity skills for thinking "outside the box."

A common issue that arises in team decision making is groupthink . This can happen when a group places a desire for mutual harmony above a desire to reach the right decision, which prevents people from fully exploring alternative solutions.

If there are frequent unanimous decisions in any of your exercises, groupthink may be an issue. Suggest that teams investigate new ways to encourage members to discuss their views, or to share them anonymously.

Exercise 2: The Great Egg Drop*

In this classic (though sometimes messy!) game, teams must work together to build a container to protect an egg, which is dropped from a height. Before the egg drop, groups must deliver presentations on their solutions, how they arrived at them, and why they believe they will succeed.

This fun game develops problem-solving and decision-making skills. Team members have to choose the best course of action through negotiation and creative thinking.

• Ideally at least six people in each team.
• Raw eggs – one for each group, plus some reserves in case of accidents!
• Materials for creating the packaging, such as cardboard, tape, elastic bands, plastic bottles, plastic bags, straws, and scissors.
• Aprons to protect clothes, paper towels for cleaning up, and paper table cloths, if necessary.
• Somewhere – ideally outside – that you can drop the eggs from. (If there is nowhere appropriate, you could use a step ladder or equivalent.)
• Around 15 to 30 minutes to create the packages.
• Approximately 15 minutes to prepare a one-minute presentation.
• Enough time for the presentations and feedback (this will depend on the number of teams).
• Time to demonstrate the egg "flight."
• Put people into teams, and ask each to build a package that can protect an egg dropped from a specified height (say, two-and-a-half meters) with the provided materials.
• Each team must agree on a nominated speaker, or speakers, for their presentation.
• Once all teams have presented, they must drop their eggs, assess whether the eggs have survived intact, and discuss what they have learned.

When teams are making their decisions, the more good options they consider, the more effective their final decision is likely to be. Encourage your groups to look at the situation from different angles, so that they make the best decision possible. If people are struggling, get them to brainstorm – this is probably the most popular method of generating ideas within a team.

Ask the teams to explore how they arrived at their decisions, to get them thinking about how to improve this process in the future. You can ask them questions such as:

• Did the groups take a vote, or were members swayed by one dominant individual?
• How did the teams decide to divide up responsibilities? Was it based on people's expertise or experience?
• Did everyone do the job they volunteered for?
• Was there a person who assumed the role of "leader"?
• How did team members create and deliver the presentation, and was this an individual or group effort?

Exercise 3: Create Your Own*

In this exercise, teams must create their own, brand new, problem-solving activity.

This game encourages participants to think about the problem-solving process. It builds skills such as creativity, negotiation and decision making, as well as communication and time management. After the activity, teams should be better equipped to work together, and to think on their feet.

• Ideally four or five people in each team.
• Paper, pens and flip charts.

Around one hour.

• As the participants arrive, you announce that, rather than spending an hour on a problem-solving team-building activity, they must design an original one of their own.
• Divide participants into teams and tell them that they have to create a new problem-solving team-building activity that will work well in their organization. The activity must not be one that they have already participated in or heard of.
• After an hour, each team must present their new activity to everyone else, and outline its key benefits.

There are four basic steps in problem solving : defining the problem, generating solutions, evaluating and selecting solutions, and implementing solutions. Help your team to think creatively at each stage by getting them to consider a wide range of options. If ideas run dry, introduce an alternative brainstorming technique, such as brainwriting . This allows your people to develop one others' ideas, while everyone has an equal chance to contribute.

After the presentations, encourage teams to discuss the different decision-making processes they followed. You might ask them how they communicated and managed their time . Another question could be about how they kept their discussion focused. And to round up, you might ask them whether they would have changed their approach after hearing the other teams' presentations.

Successful decision making and problem solving are at the heart of all effective teams. While teams are ultimately led by their managers, the most effective ones foster these skills at all levels.

The exercises in this article show how you can encourage teams to develop their creative thinking, leadership , and communication skills , while building group cooperation and consensus.

LOST AT SEA activity (FREE Critical Thinking Lesson Plans)

Lost at Sea Critical Thinking activity last updated Oct 7, 2021:

The Lost at Sea Activity is a fantastic team-building activity. 

Lost at Sea is a classic activity that can be found all across the Internet.

We’ve adapted it in our CRITICAL THINKING lesson plans to help teachers introduce the idea of criterion based decision making

Plus, we made the activity look visually appealing for school. Check it out!

Psst. it’s free 2 hours and 101 slides / pages of free content.

The original activity comes from PACE: Profession of Arms Centre of Excellence which is a dedicated champion to strengthening Air Force culture. 

• The Pace website provides a variety of tools on their teamwork page . 
• These include a series of TEAMBUILDER activities including the  original “Lost at Sea” activity

Information presented on AF.mil is considered public information.

So, in this Educircles version of Lost at Sea, this activity has been adapted to highlight the importance of criteria based thinking (critical thinking), instead of relying solely on emotional intuitive responses.

In the original activity:

• Students are divided into groups. 
• They are given a hypothetical scenario where they are on a yacht in the middle of the ocean. 
• The yacht catches on fire and the students are given a list of 15 items that they need to rank in order of importance. 
• At the end, the answers are given. (Rankings provided by an expert, in this case, the US Coast Guard) 

The original goal according to PACEsetter is a tabletop scenario designed to 

• “help individuals work together in a time constrained environment, 
• collaborate on how a project should best be accomplished and 
• experience pressure to go along with the crowd and see the consequences.” 

Lost at Sea is also a fantastic opportunity to help us think more critically.

In this Educircles version, we suggest three strategies to help students think more critically:

Use criteria 

Be open-minded.

• Be full minded  (have lots of high quality information to help make an informed decision)

We have adapted the original activity for students as follows:

• We provide a high-interest, visually appealing slideshow to introduce and explain the activity, objects, and answers to students.
• We explain with images and words what each of the 15 items are.
• We provide student worksheet that allows students to record their ranking based on their individual thinking, group thinking  and  based on criteria.

At the end of the activity, we invite students to think about strategies that might help them to 

• trick other people, and 
• think about strategies that might help them to think more critically.

Ultimately, the goal is to begin a conversation about what critical thinking is, and what it is not.

Critical Thinking Strategies used in the Lost at Sea Activity

• After students have had an opportunity to rank the 15 items based on their individual ideas, and group ideas, students are then given the criteria that the experts used.
• Criteria are a set of rules that we can use to help us make decisions. 
• In this case, the criteria (according to the US Coast Guard) are to select objects that 1) attract attention to ourselves, and 2)help us to stay alive until we are rescued. 
• in any group scenario, team members can disagree because they’re coming from different perspectives. 
• In critical thinking, it’s important to be able to stay open-minded and accept that other people’s points of view might be equally valid and deserve careful consideration.
• In fact in this scenario, some objects can be used in different ways – and depending on how they are used, they might be rank higher or lower. 
• It’s up to the students to try to remain open-minded and consider opposing points of view. 
• For example, the oil and gas mixture could be used as fuel for an engine. However, the criteria is not to try to get the land, but to stay alive until we are rescued. So from that perspective the oil and gas mixture might not be very useful. 
• On the other hand, the oil and gas mixture can be lit and create a visible signal that can be seen from far away. In this case, this item becomes incredibly useful under the goal of attracting attention to ourselves.

Be full minded (have lots of high quality information to help you make an informed decision)

• One of the challenges of this activity is that students don’t always know what all the items are, or why they might be significant. 
• In our slideshow, we explain what each item is and we provide a little bit of background information to help students make an informed decision about how to use the item.

A ship develops a leak 12 km from the shore. Despite the leak, the ship is able to move towards the shore at a speed of 8 km/hr. However, the ship can stay afloat only for 20 minutes. If a rescue vessel were to leave from the shore towards the ship, and it takes 4 minutes to evacuate the crew and passengers of the ship, what should be the minimum speed of the rescue vessel in order to be able to successfully rescue the people aboard the ship?

(A) 53 km/hr

(B) 37 km/hr

(D) 44 km/hr

(E) 82 km/hr

Sinking ship – how to be prepared?

Posted by Nicky Smol on December 29, 2021 in Other news

Sinking ship situation

Every year millions of cargo ships, cruises and ferries make their way across the sea. Unfortunately, sometimes an emergency occurs on board of a vessel, causing a sinking ship situation. Between 2011 and 2020, 876 vessels were lost at sea. The majority of ships lost during this period, around 348, were cargo ships ( Statista Research Department) .

While cruise ships are only a small percentage of the sea vessels, there are usually much more people aboard. You probably remember the disaster sinking of the Costa Concordia ? On January 13, 2012, the Costa Concordia   wrecked just off the coast of an Italian island. Even though the water was shallow and the ship was close to shore, many people were killed or injured.

Fortunately, disasters like these are rare and cruise ships operate under a number of international rules. Vessels worldwide need a variety of safety procedures and appropriate emergency equipment on board. In this case, when an emergency occurs, they are able to handle unusual situations quickly and safely.

At T-ISS, we provide SOLAS (Safety of Life at Sea) Maritime Safety Products for all kinds of vessels. We want to help you make your ship safer by providing you with the best products and by being an expert in all the required rules and regulations.

Photo Costa Concordia NOS

IMO escape route signs

When a ship starts sinking, all people on board must be evacuated to safety. The standard evacuation signal used for a sinking ship is seven short horn blasts, followed by one long horn blast. But how do you know what to do during an evacuation? Especially on cruise ships, most passengers will not know what to do or where to go. That is where escape route signs come in.

Escape route signs are provided to guide people to safety when an emergency occurs. Escape route signs on board a vessel direct people to the nearest assembly point.  From the assembly point, passengers will be guided into the life rafts by crew members of the ship.

At T-ISS we offer environmentally friendly, back-printed photoluminescent PETX signage products. These signs, under the brand name SafeSign, are photoluminescent in case of a power out.

Rescue boat hook PX03

When the ship is being evacuated, rescue boats and life rafts have to be released into the water. No matter the type of lifeboat, the most important consideration is to make sure it releases quickly and safely. This way people in distress can be evacuated as fast as possible.

The lifeboats can be quickly deployed from ships with the help of a rescue boat hook. The T-ISS Rescue boat hook PX03 is a manual release hook. The release hook can handle a safe working load of 15 kN. The hook is easy to operate/maintain and comes with a 5-year service life. It is designed to be opened manually and can be operated by one person. By pushing the release handle in an upward position, the hook will open, releasing the lifeboat into the water.

Hydrostatic Release Unit for a sinking ship

Once certain compartments of a ship are filled with water, the ship can sink faster. In some cases, this means that there is no time to unhook all the liferafts manually. That is why many vessels use a Hydrostatic Release Unit (or HRU).

An HRU is activated by water pressure. This means that the HRU will activate itself underwater. The water pressure causes the knife in the HRU to cut through the rope. This then automatically releases the life raft into the water.

The T-ISS SeaMate Ve-1 hydrostatic release unit is designed to operate in all conditions. From extreme heat to the polar environment. Our HRU also fits on remote release systems. This enables you to release life rafts remotely.

Solasflex Retro-reflective tape

The Solasflex Retro-reflective tapes are used to increase visibility on liferafts, lifeboats, and life jackets. The reflective tape reflects any light and amplifies it to provide enhanced night-time reflected visible brightness in dark areas, especially poorly lit areas.

All our reflective tapes consist of an encapsulated optical design with a high reflective value that is clearly visible from every angle, both in dry and wet conditions. This very high reflectivity allows the tape to see thousands of feet instead of hundreds. In search and rescue operations, the extremely high reflectivity tape can mean the difference between life and death.

Life jackets + life jacket lights

In a sinking ship situation, lifejackets can mean the difference between life and death. The water at sea can be very rough and cold, making it very hard to keep your head above the water. Even when you are an excellent swimmer. That is why wearing an inflatable life jacket can make an enormous difference between life and death.

The Besto 300 Newton inflatable twin chamber lifejacket  is an automatically operated jacket. It can be easily worn on top of the crew’s gear. When an emergency occurs, the life jacket can be inflated. The Besto 300 Newton inflatable twin chamber lifejacket is specifically designed for use on the open sea. It is suitable for the most extreme weather conditions. In addition, it is designed in accordance with the latest SOLAS/MED requirements.

A lifejacket will increase the chances of survival tremendously. But it can be hard to spot a man overboard in the rough waters, especially when the ship sinks at night. Therefore a  lifejacket light  will make it easier for the crew to find the missing crewmember.

The automatically water-activated LED lifejacket light is unique in its brightness and duration. This is possible because it uses Alkaline batteries instead of standard Lithium batteries. The compact and thin design is equipped with a light bubble/dome while maintaining the integrity of inflatable lifejackets. It is delivered with a clip that fits almost any life jacket.

The light is deactivated by pressing the power button on the front side. If the light after disruption is brought back to automatic mode, and the water contacts are dry, splash water on the contacts, and the light goes on again.

The ship crashed into a reef and is sinking. Now the entire crew must be evacuated. All n crew members have already lined up in a row (for convenience let's label them all from left to right with positive integers from 1 to n ) and await further instructions. However, one should evacuate the crew properly, in a strict order. Specifically:

The first crew members to leave the ship are rats. Then women and children (both groups have the same priority) leave the ship. After that all men are evacuated from the ship. The captain leaves the sinking ship last.

If we cannot determine exactly who should leave the ship first for any two members of the crew by the rules from the previous paragraph, then the one who stands to the left in the line leaves the ship first (or in other words, the one whose number in the line is less).

For each crew member we know his status as a crew member, and also his name. All crew members have different names. Determine the order in which to evacuate the crew.

The first line contains an integer n , which is the number of people in the crew ( 1 ≤  n  ≤ 100 ). Then follow n lines. The i -th of those lines contains two words — the name of the crew member who is i -th in line, and his status on the ship. The words are separated by exactly one space. There are no other spaces in the line. The names consist of Latin letters, the first letter is uppercase, the rest are lowercase. The length of any name is from 1 to 10 characters. The status can have the following values: rat for a rat, woman for a woman, child for a child, man for a man, captain for the captain. The crew contains exactly one captain.

Print n lines. The i -th of them should contain the name of the crew member who must be the i -th one to leave the ship.

How two high school students solved a 2,000-year-old math puzzle

A high school math teacher at St. Mary's Academy in New Orleans, Michelle Blouin Williams, was looking for ingenuity when she and her colleagues set a school-wide math contest with a challenging bonus question. That bonus question asked students to create a new proof for the Pythagorean Theorem, a fundamental principle of geometry, using trigonometry. The teachers weren't necessarily expecting anyone to solve it, as proofs of the Pythagorean Theorem using trigonometry were believed to be impossible for nearly 2,000 years.

But then, in December 2022, Calcea Johnson and Ne'Kiya Jackson, seniors at St. Mary's Academy, stepped up to the challenge. The $500 prize money was a motivating factor.

After months of work, they submitted their innovative proofs to their teachers. With the contest behind them, their teachers encouraged the students to present at a mathematics conference, and then to seek to publish their work. And even today, they're not done. Now in college, they've been working on further proofs of the Pythagorean Theorem and believe they have found five more proofs. Amazingly, despite their impressive achievements, they insist they're not math geniuses.

"I think that's a stretch," Calcea said.

The St. Mary's math contest

When the pair started working on the math contest they were familiar with the Pythagorean Theorem's equation: A² + B² = C², which explains that by knowing the length of two sides of a right triangle, it's possible to figure out the length of the third side.

When Calcea and Ne'Kiya set out to create a new Pythagorean Theorem proof, they didn't know that for thousands of years, one using trigonometry was thought to be impossible.  In 2009, mathematician Jason Zimba submitted one, and now Calcea and Ne'Kiya are adding to the canon.

Calcea and Ne'Kiya had studied geometry and some trigonometry when they started working on their proofs, but said they didn't feel math was easy. As the contest went on, they spent almost all their free time developing their ideas.

"The garbage can was full of papers, which she would, you know, work out the problems and if that didn't work, she would ball it up, throw it in the trash," Cal Johnson, Calcea's dad, said.

Neliska Jackson, Ne'Kiya's mother, says lightheartedly, that most of the time, her daughter's work was beyond her. 

To document Calcea and Ne'Kiya's work, math teachers at St. Mary's submitted their proofs to an American Mathematical Society conference in Atlanta in March 2023.

"Well, our teacher approached us and was like, 'Hey, you might be able to actually present this,'" Ne'Kiya said. "I was like, 'Are you joking?' But she wasn't. So we went. I got up there. We presented and it went well, and it blew up."

Why Calcea' and Ne'kiya's work "blew up"

The reaction was insane and unexpected, Calcea said. News of their accomplishment spread around the world. The pair got a write-up in South Korea and a shoutout from former first lady Michelle Obama. They got a commendation from the governor and keys to the city of New Orleans. 

Calcea and Ne'Kiya said they think there's several reasons why people found their work so impressive. 

"Probably because we're African American, one," Ne'Kiya said. "And we're also women. So I think-- oh, and our age. Of course our ages probably played a big part."

Ne'Kiya said she'd like their accomplishment to be celebrated for what it is: "a great mathematical achievement."

In spite of the community's celebration of the students' work, St. Mary's Academy president and interim principal Pamela Rogers said that with recognition came racist calls and comments. 

"[People said] 'they could not have done it. African Americans don't have the brains to do it.' Of course, we sheltered our girls from that," Rogers said. "But we absolutely did not expect it to come in the volume that it came."

Rogers said too often society has a vision of who can be successful.

"To some people, it is not always an African American female," Rogers said. "And to us, it's always an African American female."

Success at St. Marys 

St. Mary's, a private Catholic elementary and high school, was started for young Black women just after the Civil War. Ne'Kiya and Calcea follow a long line of barrier-breaking graduates. Leah Chase , the late queen of Creole cuisine, was an alum. So was Michelle Woodfork, the first African American female New Orleans police chief, and Dana Douglas, a judge for the Fifth Circuit Court of Appeals. 

Math teacher Michelle Blouin Williams, who initiated the math contest, said Calcea and Ne'Kiya are typical St. Mary's students. She said if they're "unicorns," then every student who's matriculated through the school is a "beautiful, Black unicorn."

Students hear that message from the moment they walk in the door, Rogers said. 

"We believe all students can succeed, all students can learn," the principal said. "It does not matter the environment that you live in."

About half the students at St. Mary's get scholarships, subsidized by fundraising to defray the $8,000 a year tuition. There's no test to get in, but expectations are high and rules are strict: cellphones are not allowed and modest skirts and hair in its natural color are required. 

Students said they appreciate the rules and rigor.

"Especially the standards that they set for us," junior Rayah Siddiq said. "They're very high. And I don't think that's ever going to change." 

What's next for Ne'Kiya and Calcea

Last year when Ne'Kiya and Calcea graduated, all their classmates were accepted into college and received scholarship offers. The school has had a 100% graduation rate and a 100% college acceptance rate for 17 years, according to Rogers.

Ne'Kiya got a full ride in the pharmacy department at Xavier University in New Orleans. Calcea, the class valedictorian, is studying environmental engineering at Louisiana State University. Neither one is pursuing a career in math, though Calcea said she may minor in math.

"People might expect too much out of me if I become a mathematician," Ne'Kiya said wryly.
