How to save your project with a premortem brainstorm

Reading time: about 7 min


  • Strategic planning

There is a team-building exercise you might be familiar with that goes something like this:

  • Participants are divided into two teams.
  • Each team is given 30 seconds to build a free-standing tower using a set of dominoes.
  • The team that builds the tallest tower that remains standing after 30 seconds is the winner.
  • One team is instructed to start building the tower immediately.
  • The other team is instructed to use an extra 10 to 15 seconds to plan how they will build the tower.

What normally happens in this exercise is that the team that has time to plan, even for a short time, makes better decisions that help them to build the taller tower. The lesson learned is simple: even a little bit of planning can go a long way to ensure success.

Another lesson is that if a little planning is good, then more planning must be better. And part of that planning should include risk assessment. This is where the idea of a premortem brainstorm or analysis session comes in.

What is a premortem?

Mortem is a Latin word that means “death.” When a person dies, a pathologist might perform a postmortem exam to find out the cause of death. The things the pathologist learns from the postmortem might lead to cures that can prevent future deaths. 

In a business setting, a postmortem is an analysis of a project you’ve recently completed. This does not mean that the project died or that it was a failure. It just means that you want to understand what went well and what didn’t go so well so you can apply the lessons you learn to the next project.

A premortem is kind of like the opposite of a postmortem. It is a risk management method that was developed in 2007 by Gary Klein. Instead of examining what went wrong, the team comes together to analyze what could go wrong. Then you work backward to come up with a plan that can keep potential problems from derailing your project. The goal is to increase the chances of your project’s success—to hedge against failure by discussing possible failure points in advance.

Why should you do a premortem analysis?

You may have heard that projects fail at an alarmingly high rate—70% according to most reports. Another recent report found that agile projects are three times more likely to succeed than traditional waterfall projects.

The point is that some projects fail. And a couple of the most common reasons projects fail can be attributed to these common biases: 

  • Confirmation bias: This is the tendency that people have to seek out and accept information or ideas that support what they already believe. This manifests itself in project objectives or competitive analyses that are fully honest and paint an overly rosy picture about your current state because doing so feels less painful than attacking assumptions.
  • Overconfidence: This is the tendency to be more confident in our abilities than is reasonable. Overconfidence bias is what leads managers or team members to promise more than they can feasibly deliver in a specified amount of time. It can cause people to act without objective reflection on what can actually be done.

It’s helpful to be aware of these biases during premortem analysis, because premortem brainstorming encourages team to look at things more objectively. While the team identifies what might go wrong in the next project, the premortem encourages open and objective discussions about doubts, concerns, and misgivings anybody might have going into a new project. Identifying possible problems and discussing concerns leads to the creation of proactive measures that can stop the issues before they come up. 

The premortem encourages people who might previously have been reluctant to point out what they see as flaws or weaknesses in the plan because they don’t want to “rain on the parade.” In addition, the premortem can help your team members to be more alert and react more quickly to signs that the project might fail.

How do you conduct a premortem analysis?

A premortem is not a complicated meeting, but it can be very powerful as it prepares you to recognize and prevent a potential crisis. The following steps can help you to conduct a successful premortem analysis.

Step 1: Prepare

Make sure that all stakeholders and team members with significant roles can attend the meeting. If important stakeholders don’t attend, things can be overlooked that might blow up in your face later.

Chances are your company is currently working in some type of hybrid work model. This means that the premortem likely won’t be face-to-face (which is ideal) with everybody physically in the same room. So you’ll need to create a digital document that team members can access and work on in real-time no matter where they attend the meeting. For example, a Lucidspark premortem template can help bring your team together to express their ideas on visual canvas where you can quickly jot ideas down on virtual sticky notes.

Divide your document into columns with the following headers:

  • What could cause us to miss our deadline?
  • What will keep our project on time?
  • What does this project need that we don’t have?
  • What do we already have that this project needs?
  • What lessons have you learned from past projects?
  • What are you worried about?
  • What are you excited about?
  • To Discuss

Step 2: Set the stage

The premortem does not need to focus on the negative. So you might want to start the meeting by asking your team to think about these questions:

  • What could go wrong with the project?
  • What could go right with the project?

Considering the potential positives and negatives will keep the team focused on the project and help them to come up with better ideas.

Step 3: Brainstorm

Give everybody some time to answer the questions. You can let them work in groups or individually. Encourage creativity and have them write down everything they can think of. All ideas are worth considering if the reasoning makes sense. Have them add their answers to the collaboration document in the appropriate columns.

Step 4: Merge similar ideas together

You will probably have a lot of similar answers to each question. Merge similar ideas together to free up space on the document. In some cases you may need to flesh out some ideas a little bit more. For example, a comment like “the technology doesn’t work” doesn’t really define why the project might fail. It’s more helpful to describe which specific parts of the technology might cause the project to fail.

Step 5: Identify the threats

The participants evaluate the ideas on the document and vote on the ones that they believe could pose the biggest threat to the project’s success. Give each person a set number of votes, which forces the team to prioritize the biggest issues.

Step 6: Identify the successes

Follow the same format from step 5 to vote for what the team members believe are the keys to the project’s potential success.

Step 7: Discussion 

Move the three ideas that got the most votes to the To Discuss column. Take time to discuss each idea and develop action items for each.

Step 8: Take action

Review the action items. Make sure that everybody knows which teams or individuals have responsibility and ownership for each action item. Also ensure that the action items each have a deadline.

Premortem tips and best practices

There are a few things you might want to consider while running a premortem that can enhance the steps outlined above, including:

  • Don’t generalize. Be as specific as possible to back up reasonings for possible project failures.
  • Don’t use the meeting to air grievances or to try settling scores.
  • Make sure the premortem document is located where your team members can easily find it for reference. This helps everybody to stay up-to-date when there are changes to the document.
  • Add the action items to a centrally located project board or virtual board where the team can easily track their progress.
  • Review and revise as needed to ensure that you’re aware of the project’s risks and that solutions are being developed.
