Pre-Mortem

Imagine your project has failed spectacularly—then work backward to identify why. Apply Gary Klein's "prospective hindsight" technique to catch failures before they happen.

When to Use This Skill

• Before launching a product, campaign, or major initiative

• Before making an important decision (hiring, investment, partnership)

• Starting a project to identify risks the team hasn't considered

• When overconfident and everyone agrees the plan is great

• Before committing resources to a significant undertaking

• In team planning to surface concerns people might hesitate to share

Methodology Foundation

Aspect Details

Source Gary Klein (1989), cognitive psychologist, naturalistic decision making pioneer

Expert Klein's research shows pre-mortems increase accuracy of identifying reasons for outcomes by 30%

Core Principle "Prospective hindsight" - imagining an event has already occurred dramatically improves our ability to explain it. The future feels distant; the past feels real.

Claude Does You Decide

Structures production workflow Final creative direction

Suggests technical approaches Equipment and tool choices

Creates templates and checklists Quality standards

Identifies best practices Brand/voice decisions

Generates script outlines Final script approval

What This Skill Does

• Surfaces hidden risks - Finds dangers invisible to forward-looking planning

• Gives permission to criticize - Team members can voice concerns safely

• Reduces overconfidence - Counters planning fallacy and optimism bias

• Improves plans before execution - Fix problems when they're cheap to fix

• Creates psychological safety - "We're imagining failure" feels safer than "I think this will fail"

How to Use

Run a Pre-Mortem

Run a Pre-Mortem on this project: [describe the project, product, or decision]

It's one year from now and this has failed completely. What happened?

Stress-Test a Decision

Pre-Mortem this decision: [describe the decision you're considering]

Assume we made this choice and it went badly. What went wrong?

Team Pre-Mortem Facilitation

Help me facilitate a Pre-Mortem session for my team. Project: [description] Team size: [number] Time available: [duration]

Provide the agenda, questions to ask, and how to synthesize findings.

Instructions

When facilitating a Pre-Mortem, follow this systematic process:

Step 1: Set the Stage

Pre-Mortem Setup

Project/Decision: ________________________________

Timeline: [Imagine we're looking back from X months/years]

The Scenario: "It is [future date]. This project has failed—not just underperformed, but failed spectacularly. The results are in and they're bad.

We're now conducting a post-mortem to understand what went wrong. Looking back, it's obvious why this failed..."

Rules:

1. Failure has ALREADY happened (this is a fact in this exercise)
2. Everyone must contribute at least one reason
3. No defending the plan (we're explaining failure, not preventing it)
4. Be specific, not vague
5. "I had a bad feeling" is valid (hindsight makes it concrete)

Step 2: Individual Failure Generation (Silent)

Individual Brainstorm (5-10 minutes)

Each person silently writes answers to:

"Looking back, this project failed because..."

Prompt Questions:

• What did we overlook?
• What assumption proved wrong?
• What external event derailed us?
• Who let us down (vendor, team member, partner)?
• What resource ran out?
• What competitor move hurt us?
• What customer behavior surprised us?
• What technical problem emerged?
• What communication failure occurred?
• What timeline assumption was wrong?

Why Silent First:

• Prevents groupthink

• Allows introverts equal voice

• Captures diverse concerns before discussion narrows focus

Step 3: Share and Cluster

Round Robin Sharing

Process:

1. Each person shares ONE reason (no discussion yet)
2. Continue rounds until all reasons shared
3. Capture on whiteboard/doc as shared

Clustering: Group similar failure reasons into categories:

EXECUTION FAILURES

EXTERNAL FACTORS

RESOURCE CONSTRAINTS

ASSUMPTION FAILURES

PEOPLE/TEAM ISSUES

TIMING/MARKET

Step 4: Analyze and Prioritize

Risk Assessment Matrix

For each failure reason, assess:

Scoring:

• High Likelihood + High Impact + Late/Never Detection = CRITICAL
• Medium/Medium/Early = MANAGEABLE
• Low/Any/Early = MONITOR

Priority Failures

CRITICAL (Must Address):

MONITOR (Watch Closely):

Step 5: Create Prevention/Mitigation Plans

Prevention Strategies

For each critical risk:

Risk: [Failure Reason 1]

Early Warning Signs:

Prevention Actions:

If It Happens Anyway (Mitigation):

Owner: ____________ Review Date: ____________

Risk: [Failure Reason 2]

[Repeat structure]

Tripwires (Automatic Triggers)

"If we see [sign], we immediately [action]"

1. If ______________, then ______________
2. If ______________, then ______________
3. If ______________, then ______________

Step 6: Integrate into Plan

Updated Project Plan

Original Assumptions (Now Questioned)

New Safeguards Added

• ________________________________
• ________________________________
• ________________________________

Monitoring Dashboard

Track these metrics as early warning system:

Scheduled Check-ins

• Week 2: Review assumption #1
• Week 4: Check metric #2
• Month 2: Full pre-mortem review

Examples

Example 1: Product Launch Pre-Mortem

Context: SaaS company launching new enterprise product in 3 months.

Input:

"We're launching our enterprise product in Q2. Everyone's excited. Run a Pre-Mortem—what killed us?"

Output:

The Scenario: "It's September. Our Q2 enterprise launch failed. We've burned through our runway, the product hasn't gained traction, and we're considering a pivot. What went wrong?"

Failure Reasons Generated:

EXECUTION FAILURES:

• We underestimated enterprise sales cycle (6-12 months, not 2)

• Security review requirements we didn't anticipate (SOC2, etc.)

• The product wasn't actually enterprise-ready (missing audit logs, SSO)

• Support couldn't handle enterprise customer expectations

MARKET/TIMING: 5. Enterprise budgets were frozen due to economic conditions 6. Two competitors launched similar products in Q1 7. Target companies in "wait and see" mode

INTERNAL/TEAM: 8. Sales team had no enterprise experience 9. Engineering bandwidth split between launch and bug fixes 10. Marketing message didn't resonate with enterprise buyers

RESOURCE: 11. Ran out of runway before enough deals closed 12. Couldn't hire enterprise sales rep fast enough

Risk Assessment:

Failure Reason Likelihood Impact Priority

Enterprise sales cycle underestimated HIGH HIGH CRITICAL

Product not enterprise-ready HIGH HIGH CRITICAL

Budget freeze MEDIUM HIGH WATCH

Competitive launch MEDIUM MEDIUM MONITOR

Sales team inexperience HIGH HIGH CRITICAL

Prevention Plan:

Risk 1: Sales Cycle Underestimated

• Prevention: Start enterprise conversations NOW (3 months early)

• Validation: Have 5 LOIs before launch, not 5 "interested" calls

• Tripwire: If no LOIs by Week 4, pause launch

Risk 2: Product Not Enterprise-Ready

• Prevention: Hire enterprise advisor to audit requirements

• Action: Prioritize SSO, audit logs, SLA before launch

• Tripwire: If security questionnaire failure, delay launch

Risk 3: Sales Team Inexperience

• Prevention: Hire one senior enterprise rep or consultant

• Alternative: Partner with enterprise-focused reseller

• Validation: Close one pilot before full launch

Updated Plan:

• Push launch to Q3 (realistic timeline)

• Add SOC2 certification to roadmap

• Hire enterprise sales lead in Q1

• Secure 3 design partners before public launch

Example 2: Hiring Decision Pre-Mortem

Context: Startup about to make critical senior hire.

Input:

"We're about to hire a VP of Engineering. $300K salary, equity, big commitment. Pre-Mortem this decision—how did this hire fail?"

Output:

The Scenario: "It's 12 months later. The VP of Engineering hire was a disaster. We've parted ways (expensively), the team is demoralized, and we've lost 6 months of progress. What happened?"

Failure Reasons:

WRONG FIT:

• Great at BigCo process, couldn't handle startup ambiguity

• Culture mismatch—too hierarchical for our flat structure

• Technical skills outdated (legacy stack experience)

• Wanted to build empire, not ship product

POOR PROCESS: 5. We were desperate and moved too fast 6. References were from friends, not actual reports 7. Didn't test actual work (no trial project) 8. Founder charisma masked red flags in interviews

WRONG EXPECTATIONS: 9. We said "VP" but needed "player-coach" 10. Compensation expectations kept growing 11. They expected more team/budget than we had

EXTERNAL: 12. Counter-offers pulled them back mentally 13. Their spouse hated the relocation 14. They took the job as a "stepping stone"

Risk Assessment:

Failure Reason Likelihood Impact Priority

Wrong for startup stage HIGH CRITICAL CRITICAL

Poor reference checking MEDIUM HIGH CRITICAL

Expectations mismatch HIGH HIGH CRITICAL

No trial period MEDIUM HIGH ACTION

Prevention Plan:

Risk 1: Wrong for Startup Stage

• Prevention: Explicitly discuss startup chaos in interview

• Test: "Tell me about a time you shipped with incomplete specs"

• Red flag: All examples from large companies

Risk 2: Poor Reference Checking

• Prevention: Talk to people THEY didn't list

• Minimum: 2 former direct reports (not friends)

• Ask: "Would you enthusiastically rehire them?"

Risk 3: Expectations Mismatch

• Prevention: Written expectations doc, signed

• Include: Budget, team size, first-year goals

• Discuss: "What if budget is cut in half?"

Risk 4: No Trial Period

• Prevention: Paid 2-week trial project before offer

• Alternative: Advisory period first

• At minimum: Pair on real problem for half-day

Updated Hiring Process:

• Add "startup chaos" scenarios to interview

• Reference check includes LinkedIn outreach to unlisted people

• Written expectations document

• 2-week paid trial before final offer

• 90-day milestone check-in

• What dependency let us down?

PEOPLE

• Who underperformed or left?
• What conflict derailed us?
• What communication failed?

RESOURCES

• What resource ran out?
• What was more expensive than planned?
• What took longer than expected?

MARKET/EXTERNAL

• What changed in the market?
• What competitor move hurt us?
• What customer behavior surprised us?

ASSUMPTIONS

• What "fact" proved wrong?
• What did we overlook?

Pre-Mortem vs Post-Mortem

When to Use Each

PRE-MORTEM (Before)

✓ Project hasn't started yet ✓ Major decision pending ✓ Team is overconfident ✓ High-stakes initiative ✓ Want to find problems early

POST-MORTEM (After)

✓ Project has completed (success or failure) ✓ Want to capture lessons learned ✓ Building institutional knowledge ✓ Improving future processes

KEY DIFFERENCE

Post-Mortem: "What happened?" (Limited by actual events) Pre-Mortem: "What COULD happen?" (Unlimited imagination)

Research shows Pre-Mortem generates 30% more failure reasons. Why? "Prospective hindsight" makes imagined failure feel real.
