Pre-mortem

What it is

Gary Klein's technique: before committing to a decision, assume it has already failed, and explain why. The tense is the whole mechanism. Asking "what could go wrong?" invites hedged, socially safe answers; asking people to account for a failure that has definitively happened gives them permission to say the thing they would otherwise keep to themselves.

The premise

Stated as history, not prediction. "It is three years from now. This failed badly." Not "might fail" — did fail. Certainty is what unlocks the honesty.

Silent generation

Everyone writes their own account before anyone speaks. Without this the first voice anchors the room and you surface one failure mode instead of eight.

Collection without debate

All accounts read out, none argued with. Arguing about plausibility is precisely the reflex the exercise exists to suspend.

Ranking

Only now do you judge: each failure mode weighed for likelihood and for damage. You are hunting the two or three that are both.

Warning signs and changes

For each top failure, what you would have observed in year one — and what you change in the plan today. A pre-mortem that ends in a list has done half its job.

How you run it

1. Set the scene in the past tense"It is three years from now. This failed badly." Not "might fail" — did fail. The certainty is what frees people to speak.
2. Write silently firstEveryone writes their own account before anyone speaks, or the first voice anchors the room and you get one failure mode instead of eight.
3. Read them out without debateCollect all of them. Arguing about plausibility is exactly the reflex the exercise exists to suspend.
4. Rank by plausibility times damageNow you can judge. You want the two or three that are both likely and severe.
5. Convert to warning signs and changesWhat would we have seen in year one, and what do we change today? A pre-mortem that ends in a list has done half its job.
