What is Blameless Post-Mortem?
A structured retrospective conducted after an incident, failure, or significant miss, with the explicit commitment that no individual will be punished or blamed. The goal is systemic learning: what conditions made this failure possible, and what changes will prevent recurrence?
My perspective
In practice
Pioneered in Site Reliability Engineering (SRE) culture at Google. The blameless framing is not just kind. It's strategically correct. Blame terminates learning; blamelessness extends it. Teams that run great post-mortems treat failure as a data point rather than a crime scene.
