Her Success Coach helps women leaders build confidence, overcome self-doubt, and lead with clarity. Cambridge-trained, evidence-based coaching for senior women in tech, business, and finance.

A post-mortem examines what went wrong after a project fails. A pre-mortem, developed by psychologist Gary Klein, flips this timeline. Before you launch a project, initiative, or strategy, you imagine that it has already failed spectacularly. Then you work backward to identify the most likely causes of that failure. This deceptively simple technique is one of the most powerful risk-mitigation tools in a leader's arsenal, and it directly addresses the cognitive biases that cause smart teams to make catastrophic mistakes.

The Psychology Behind the Pre-Mortem

Why is imagining future failure so much more effective than simply asking "What could go wrong?"

The answer lies in a concept psychologists call "prospective hindsight." Research by Mitchell, Russo, and Pennington (1989) found that people generate 30% more reasons for an outcome when they are told it has already happened compared to when they are asked to predict whether it might happen. When you say "imagine this has failed," you activate a different cognitive mode than when you say "what risks do you see." The former feels concrete and real. The latter feels abstract and hypothetical.

Pre-mortems also counter two of the most dangerous biases in leadership:

• Optimism bias: The natural tendency to believe that your plan is more likely to succeed than base rates would suggest. After investing time and energy into a strategy, teams become emotionally attached to its success.
• Groupthink: The pressure to conform to the group's enthusiasm, especially when a senior leader is championing the initiative. Pre-mortems give explicit permission to voice concerns, which is critical for psychological safety.

How to Run a Pre-Mortem: Step by Step

Step 1: Set the Scene

Gather the team involved in the project. Explain the exercise: "We are going to imagine it is six months from now. This project has failed. Not just underperformed, but failed decisively. Our job today is to explain why."

The language matters. "Failed decisively" is more powerful than "did not meet targets" because it forces the imagination to engage fully. You want the team to feel the failure viscerally.

Step 2: Individual Brainstorming (5-10 Minutes)

Each person independently writes down every plausible reason for the failure. Individual brainstorming before group discussion is essential because it prevents anchoring, where the first person to speak influences everyone else's thinking. This is particularly important for ensuring that quieter team members and less senior voices contribute equally.

Step 3: Share and Consolidate

Go around the room. Each person shares one reason at a time, rotating until all unique reasons are captured. Group similar reasons together. You will typically end up with 10-25 distinct failure causes.

Common categories include:

• Assumptions that proved wrong: "We assumed customers would adopt feature X, but they did not."
• Resource and capacity issues: "The engineering team was pulled onto another priority."
• Stakeholder and political risks: "The new VP deprioritised our initiative."
• External factors: "A competitor launched a similar product first."
• Execution failures: "We did not have clear ownership of the critical integration."
• Communication breakdowns: "The sales team did not understand the value proposition."

Step 4: Prioritise Risks

Not all failure causes are equally likely or impactful. Use a simple 2x2 (likelihood × impact) to prioritise. Focus your mitigation efforts on the high-likelihood, high-impact risks. For the highest-priority risks, assign owners and develop specific mitigation plans.

Step 5: Integrate Into the Plan

The pre-mortem is not a standalone exercise. The risks and mitigations identified should be integrated directly into the project plan, with checkpoints at key milestones to reassess. The most common failure of pre-mortems is running them and then filing the output in a drawer. Make the findings a living part of your strategic plan implementation.

Real-World Example: Product Launch Pre-Mortem

A Head of Product at a SaaS company ran a pre-mortem before launching a major new feature targeting enterprise clients. The team surfaced 18 failure causes. Three stood out as high-priority:

• "Enterprise security review took three months longer than expected." Mitigation: start the security review process with two pilot customers immediately, before development was complete.
• "The sales team sold the feature incorrectly because they didn't understand its limitations." Mitigation: create a detailed sales enablement guide and run mandatory training sessions before launch.
• "Key engineer left during development." Mitigation: ensure knowledge sharing and documentation from day one, with a designated backup for every critical system.

All three mitigations were implemented. The security review issue turned out to be the most prescient, the pilot process identified compliance gaps that would have delayed the full launch by months if discovered later.

Why Pre-Mortems Are Essential for Women Leaders

Research consistently shows that women leaders' failures are scrutinised more harshly and attributed more to lack of ability, while men's failures are more often attributed to circumstance. This asymmetry makes proactive risk management even more important for women in leadership:

• Pre-mortems demonstrate strategic foresight. When you can articulate risks and mitigations before a project begins, you build executive presence and credibility.
• They protect your team. By identifying risks early, you shield your team from preventable failures that could damage their careers and morale.
• They create psychological safety. Running a pre-mortem signals that you value honest assessment over optimistic cheerleading. This encourages the kind of candid communication that high-performing teams require.
• They counter the "prove it again" dynamic. Research from Joan C. Williams shows that women leaders often face a "prove it again" bias. Having documented risk analysis and mitigation strategies provides evidence of thorough strategic thinking.

When to Use a Pre-Mortem

• Before any major initiative or project launch
• Before presenting a strategy to the board or senior leadership
• Before making a significant organisational change (restructuring, new processes, cultural shifts)
• Before entering a new market or partnership
• Before making a critical hire (What would make this hire fail?)

Essentially, any decision where the cost of failure is high and recovery is difficult deserves a pre-mortem.

Common Mistakes

• Running it too late. A pre-mortem done the day before launch is too late to make meaningful changes. Run it early enough that you can actually act on the findings.
• Not creating psychological safety. If team members fear punishment for voicing concerns, they will not share genuine risks. The facilitator must explicitly normalise and reward candid input.
• Treating it as negative thinking. A pre-mortem is not pessimism. It is strategic realism. Frame it as "We believe in this project, and we want to give it the best possible chance of success."
• Not assigning ownership for mitigations. A risk without an owner and a deadline is just a worry, not a strategy.
• Doing it once and forgetting. Revisit pre-mortem findings at key milestones. New risks emerge as contexts change.

Pairing With Other Frameworks

• Use Six Thinking Hats (Black Hat mode) to structure the risk identification phase.
• Apply the MECE framework to ensure your risk categories are comprehensive and non-overlapping.
• Use a decision matrix to prioritise which risks require active mitigation versus passive monitoring.
• Combine with the OODA Loop for ongoing reassessment as the project progresses.

The Leader Who Plans for Failure Rarely Experiences It

The pre-mortem is a paradox: by vividly imagining failure, you make it far less likely. The leaders who build this practice into their decision-making process do not just avoid disasters. They build reputations for strategic foresight, earn the trust of their teams and stakeholders, and create the conditions for consistent, sustainable success.

Try it with your next project. Gather your team, imagine the worst, and plan for it. The 60 minutes you invest may be the most valuable strategic conversation you have all quarter.
