Close the loop

A postmortem reviews a finished project to extract what worked, what failed, and why. Done blamelessly, it converts costly experience into reusable knowledge for the team.

  • State the goal and the actual outcome plainly.
  • Trace key decisions and their effects.
  • Separate luck from skill in the result.

From story to lessons

The value is in concrete, transferable takeaways, not vague regret. Each lesson should change a future default.

  • Record landmines like a specific leakage trap you hit.
  • Capture what to do differently as a checklist item.
  • Note metrics or monitors you wish you had earlier.

The review flow

A good postmortem makes the next project start smarter.

Key idea

A blameless postmortem turns a finished project into transferable lessons by tracing decisions to outcomes and recording concrete landmines and new defaults for next time.
