Blameless postmortems

A blameless postmortem explains how the system and process allowed an incident. It does not ask who made the mistake. People act sensibly given what they knew at the time.

So ask why the action seemed reasonable, what signal was missing and which safeguard failed. A good write-up has a timeline, the impact, the contributing factors, what went well, and action items with owners and dates. Blame makes people hide information, and that makes the next incident more likely and harder to understand. Share postmortems across teams, because the same failure is often waiting elsewhere.
