Blameless Post-Mortems: Learning Over Punishment¶

Incidents result from systemic factors, not individual failures; blame suppresses information sharing and prevents learning. Safety requires psychological safety to report near-misses.

Tension Addressed¶

Automation vs. Human Judgment - humans must feel safe to report failures for organizational learning

Recognizable As¶

Post-incident reviews focused on "how" not "who"; multiple contributing factors identified; action items targeting systems not people; near-miss reporting programs

Canonical Sources¶

Transfers To¶

Blamelessness doesn't mean no accountability - it means accountability for system improvements rather than individual punishment. The question is "how do we prevent this class of failure" not "who do we blame."
