Premortem Analysis
Imagine a plan has failed and work backward to identify plausible risks early, using prospective hindsight to improve preparation rather than predict the future.
A premortem asks a group to imagine that a plan has already failed, then work backward to identify plausible reasons. The exercise can surface concerns that polite optimism leaves unspoken.
A small shop imagines that its holiday online orders arrived late. The team traces possible causes: stock counts were wrong, packing took longer than expected, or a carrier cutoff was missed. Checking inventory and confirming pickup times addresses specific vulnerabilities without claiming the delay is inevitable.
Psychologist Gary Klein described prospective hindsight as a way to improve risk identification. A premortem uses that idea; it does not establish that imagined causes are likely or certain.
Before a family hosts a large gathering, they might imagine the day went badly. Possible reasons include too little food, inaccessible seating, unclear arrival times, or a relative needing a quieter space.
Give participants a few quiet minutes to write risks independently before discussing them. This can prevent the first confident speaker from narrowing everyone else's imagination.
The method is useful before a consequential launch, trip, event, or handoff. It can turn vague worry into a manageable list of conditions to check or contingency plans to prepare.
A school group imagines its museum visit failed because a student was separated from the group. A clear buddy plan and headcount points may reduce risk, while staff should still follow safeguarding procedures and adapt supervision to the students involved.
For each proposed failure, ask what evidence supports it, how serious it would be, and what practical mitigation costs. Assign an owner to actions that the group chooses to take.
The exercise can become a ritual of pessimism if every imagined event is treated as equally probable. Prioritize rather than attempting to prevent every possibility, especially when safeguards are costly.
People may also use it to criticize a plan indirectly or protect themselves from blame. Make the purpose learning and preparation, not building a record that someone predicted trouble.
A premortem complements, but does not replace, subject expertise, testing, or consultation with affected people. Revisit key risks as the plan and surrounding conditions change.

What likely-enough failure should your group plan around, and who can check the safeguard before it matters?
