Postmortems and Promotion Criteria
Holistic signal.
Overview
Postmortem contributions belong in promotion criteria, not just feature counts. Authoring quality, action-item ownership, cross-incident pattern recognition, and mentoring on postmortem authoring all signal engineering seniority. Treating reliability work as career-relevant changes which engineers volunteer to lead the next incident response.
- Holistic signal. Authoring, debrief facilitation, action-item ownership together. No single artefact carries the whole signal.
- Authoring quality. Analytical depth, evidence-linking, blameless framing. What good engineering writing looks like.
- Action-item ownership. Did the engineer ship the remediation that came out of the postmortem? Follow-through is seniority.
- Pattern recognition plus mentoring. Cross-incident pattern recognition signals seniority; teaching others to author postmortems multiplies the team’s capability.
The approach
Three habits make postmortem contribution a real career signal: signal not quota, holistic portfolio review, and mentoring counted explicitly.
- Signal not quota. Postmortem count alone is gameable. Quality and ownership are the actual signal.
- Holistic portfolio. Authoring, ownership, and mentoring reviewed together at promotion time.
- Mentoring as a criterion. Teaching others to author postmortems counts toward seniority. Multiplier effect on the team.
- Cross-incident pattern recognition plus documented criteria. Senior engineers see patterns; per-level the postmortem expectations documented in the engineering handbook.
Why this compounds
Each promotion that recognises incident contribution shapes the team’s sense of what good engineering looks like. Reliability work stops being thankless; engineers who do it well advance; the next cohort sees the path clearly.
- Culture reinforced. Incident contribution becomes recognised work, not invisible work.
- Incident response improves. Senior engineers volunteer to lead because the work is career-relevant.
- Mentoring spreads expertise. Teaching postmortem authoring multiplies team capability across years.
- Year-one investment, year-two habit. First criteria documented takes effort. By the second promotion cycle, the practice is routine.
