What are blameless postmortems?
⚡
Quick Answer
A blameless postmortem is a written incident review focused on understanding systemic causes and improving the system, rather than assigning blame to individuals.
Detailed Answer
The premise is that people act reasonably given the information and tools they had, so failures reveal weaknesses in systems and processes, not bad people. Removing blame encourages honest disclosure, which surfaces real root causes and actionable follow-ups. Good postmortems have a timeline, contributing factors, and tracked action items.
