Post-Mortem Learning
Purpose / When to Activate
Activate after:
- Significant delivery failures
- Repeated QA failures on the same area
- Delivery that missed its success metrics
- Patterns of issues that need systemic understanding
Process
- Reconstruct what happened end-to-end
- Compare expected vs actual outcomes
- Identify: technical causes, contextual gaps, decision errors, rule weaknesses
- Produce concrete failure narratives
- Extract raw lessons (non-generalized) — specific to this failure
Outputs
- Root cause analysis report
- Failure timeline
- Mapped rule gaps
- Raw lesson list (specific, not generic)
- Candidate improvement areas (for backlog or rules)
Quality Checks
- Root causes are specific, not generic ("insufficient testing" is invalid — "acceptance criterion #3 had no test coverage" is valid)
- Lessons are raw and specific, not platitudes
- Failure timeline is traceable
- Rule gaps link to specific rule files
Non-Goals
This skill must NOT:
- Propose solutions (produces inputs for backlog and rules, not fixes)
- Assign blame
- Generalize into vague lessons
Makes failures understandable and actionable. Enables serious continuous improvement.
