Intro
Post-Incident Reviews
A post-incident review is the durable record of an incident and the work that follows it. It explains what users experienced, how the system and response behaved, which conditions contributed, and what changes will reduce future harm.
The review begins after service restoration. It does not reopen the incident command process. Its job is learning: turn incomplete evidence into a shared account and convert that account into decisions with owners.
Start with learning, not blame
A blameless review examines actions in their context. People act with the information, tools, procedures, and time available to them. The useful question is not who made a mistake. It is how system design, signals, interfaces, incentives, and operating conditions made the outcome possible.
