Free Postmortem Template

A blameless postmortem structure covering timeline, impact, root cause, and concrete follow-up actions with owners.

A postmortem that doesn't produce owned, tracked follow-up actions is just a story. This template forces the structure that turns an incident review into actual prevention: a real timeline, an honest root cause (not just the trigger), and specific actions with names and dates attached.

01

Postmortem template

Fill in after the incident is resolved and things have calmed down.

  • Summary: [one paragraph, what happened and impact]
  • Timeline: [detected, escalated, mitigated, resolved — with timestamps]
  • Root cause: [the actual underlying cause, from a 5-whys pass, not just the trigger]
  • What went well / what didn't
  • Action items: [action] — [owner] — [due date]

02

Turn action items into an updated runbook

If the postmortem reveals a gap in your incident response, record the fixed process with Guidyy and link it from the action item — the fix isn't done until the runbook reflects it.
