Pre-Mortem Imagine a project already failed, then work backward to find why — like a fire drill for decisions, practiced before the real thing.
Prospective Hindsight The brain finds 30% more causes when told an event has happened than when asked what might happen — it's a grammar trick that changes how we search for answers.
Risk Register A documented list of known risks — useful, but limited to what's politically safe to write down and what senior voices agree is real.
Showstopper A failure mode that makes the entire contract or initiative fail — the kind of problem you can't afford to discover after signing.
Planning Fallacy The tendency to underestimate what can go wrong — like packing for a trip and forgetting it might rain.
Groupthink When everyone nods along in a meeting while privately worried — the pre-mortem breaks this by having people write concerns before anyone speaks.
