I run premortems after plans are formed but before they're executed.

I frame it as imagination ('this has failed; why?') so doubts flow freely.

I enforce the no-rebuttals rule so every concern gets aired.

I go around the room so quiet people contribute, not just vocal ones.

I sort surfaced risks by likelihood and preventability.

I fix the preventable failures before execution.

I accept the unpreventable risks with eyes open rather than ignoring them.

I use premortems to bulletproof plans, not to kill them.

I surface doubts that consensus and optimism had suppressed.

My plans are stronger because their failures were imagined first.
