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.
