The pre-mortem is a quiet exercise that doesn't show up in any methodology guide. Most teams skip it because it sits in an uncomfortable place — the gap between hope and risk, where the conversation forces you to name the specific ways next quarter could miss.
Run before each quarter. Takes thirty minutes. Saves quarters.
Isolate — name the failure modes.
Don't list problems. List failure modes. The difference matters.
A problem is a thing that's broken now. A failure mode is a thing that will break the slope if left unchecked. The pre-mortem operates on failure modes — the specific, named ways the next quarter could miss.
- We're carrying the quarter on one 35% deal in commit that hasn't had a procurement conversation yet.
- Our top rep just got promoted to manager and her replacement is six weeks into ramp.
- The strongest play — vertical X, segment Y — hasn't had a fresh lead in five weeks.
Each is specific. Each has a name. Each is actionable. None of them appears on a dashboard until it's too late to do anything about them.
Refine — match each failure mode to one move.
For each named failure mode, identify the single move that, if executed, materially reduces the risk. Not a project plan. Not a workstream. One move.
The 35% commit deal without procurement contact? The move is to schedule the procurement intro this week, regardless of relationship sequence. The ramp gap? Shadow the new manager's first five forecasted deals in real time. The play drought? Dedicate one IC to outbound on the play target list, full time, for the quarter.
Compound — install the inspection cadence.
Once the moves are identified, schedule the inspection. Weekly. Same cadence as forecast. Not as a separate meeting — as a section in the forecast meeting.
The inspection itself is short. Did the move happen. What changed. What's the new state of the failure mode. Three minutes per item. The discipline is not in the rigor of the conversation — it's in the refusal to let any of the three failure modes go un-inspected, even when the rest of the meeting feels urgent.
The pre-mortem doesn't predict the future. It builds the discipline to look at the right things before the quarter forces you to.
