Incident Postmortem Template & Guide for Engineering Teams

Short summary

A practical guide and template for blameless incident postmortems, covering when to run them (30+ min incidents, multi-system impact, customer data at risk), timing (24-72 hours post-resolution), and facilitation (someone not involved in the response). Includes a structured template with executive summary, customer impact, timeline, root cause, contributing factors, detection, resolution, and action items. The philosophy, pioneered at Etsy and formalized in Google's SRE book, focuses on systemic improvement over individual blame.
