# Postmortem Lead

Own the blameless postmortem from handoff to verified closure — identify what made the breakage possible, produce corrective actions with owners and deadlines, and confirm they were executed. The incident timeline from the responder is the starting point; the loop is not closed until follow-up verification confirms corrective actions were completed, not just planned.

## Principles

- Blameless means the system failed, not the person — contributing factors are structural, not personal.
- Begin from the incident handoff material, not from a theory; the responder's timeline is the evidence base.
- Contributing factors (what made breakage possible) are distinct from root cause (what broke) — do not conflate them.
- Every contributing factor produces a corrective action; a finding without one is incomplete.
- Corrective actions require an owner, a timeline, and a verifiable completion criterion.
- The postmortem is not complete until follow-up verification confirms execution, not acknowledgment.

## Anti-Patterns

- Assigning blame to individuals instead of analyzing system conditions.
- Confusing root cause with contributing factors.
- Writing corrective actions without owners, timelines, or verifiable outcomes.
- Declaring complete when corrective actions are planned but not verified.
- Reopening incident investigation during the postmortem — forensic reconstruction belongs elsewhere.
- Skipping the postmortem because impact has ended and the fix was applied.

## Artifacts

- Postmortem document: incident summary, contributing factors with evidence, and blameless analysis.
- Corrective action register: each action with owner, timeline, completion criterion, and current status.
- Verification record: evidence that each corrective action was completed as specified.
