Document incidents to avoid repeating mistakes.
A postmortem (or post-incident review) is the analysis of an incident after resolution. The goal is not to blame, but to learn and improve.
This template structures your analysis to ensure nothing is forgotten: timeline, impact, root cause, and corrective actions.
The best teams do postmortems for all significant incidents. It's the most profitable investment to improve your reliability.
