Pre-mortem

A pre-mortem, or futurespective, asks the team to imagine that an upcoming project has already failed and to explain why. Each imagined failure then gets warning signs, prevention measures and a contingency plan, before the risk becomes real.

When to use Pre-mortem

  • Before starting a project, launch or migration.
  • When the team is optimistic and risks are going unspoken.
  • Planning sessions where you want owners for the biggest risks.

Purpose: Identify risks before an upcoming sprint, release, or project.

The prompts

  • The Failure

    It failed. What went wrong?

  • Warning Signs

    What would reveal this risk early?

  • Prevention

    What could reduce its likelihood?

  • Contingency

    What will we do if it happens?

How to run a Pre-mortem: step by step

  1. 1

    Establish the failure scenario · 3 min

    Say: 'It's three months from now and this initiative has failed badly.' Make it vivid.

  2. 2

    Brainstorm potential causes · 5 min

    Silently write the reasons it failed — one per card, as if it already happened.

  3. 3

    Reveal & group risks · 7 min

    Read the risks out. Merge duplicates so each risk appears once.

  4. 4

    Prioritise risks · 5 min

    Everyone spends their votes on what matters most. Totals stay hidden until you move on.

  5. 5

    Define prevention & contingencies · 12 min

    Work through the top risks. For each, add warning signs, preventive measures and a contingency plan.

  6. 6

    Assign owners & triggers · 5 min

    Give each mitigation an owner. Use a warning sign as the trigger for the contingency.

Example

Notes a software team might write:

The Failure

  • Launch collapsed under real traffic

Warning Signs

  • p95 latency above 800 ms in staging load tests

Prevention

  • Load test at 2× expected traffic

Contingency

  • Feature flag to fall back to the old flow

Expected outcome: Prioritised risks with mitigation actions, early warning signals, and contingency plans.

Facilitation tips

  • Writing in the past tense ('it failed because…') unlocks more honest risks.
  • Focus mitigation on the top 3 risks.

Running Pre-mortem in RetroPop

Each imagined failure gets its own row with warning signs, prevention measures and a contingency plan linked to it, then risks are prioritised by vote.

Each stage comes with instructions for the facilitator and the participants and a suggested timer you can adjust. Teammates join with a link and their name; no account needed.
