Guidelines for Incident Postmortem and Fault Review

The incident postmortem guideline advocates a dialectical view of failures, rapid low‑severity recovery, and a structured process—covering background, impact scope, timeline replay, deep root‑cause analysis, SMART improvement actions, responsibility assignment, and PDCA‑validated closure—to enhance system resilience, team anti‑fragility, and knowledge sharing.
