Write Postmortems That Lead to Better Systems
Turn an incident into specific improvements rather than a search for someone to blame.
A postmortem records an incident’s impact, timeline, contributing causes, and follow-up actions. Google’s SRE approach focuses on learning and prevention. The document becomes useful when the team can identify changes that reduce recurrence or make the next failure easier to detect and recover from.
What matters
- Describe what happened using evidence and include what made recovery harder.
- Examine the conditions that shaped decisions instead of blaming individuals.
- Assign practical follow-up actions with owners and review their completion.
Practical example: A failed release review identifies a missing validation step and an unclear rollback procedure, then assigns both improvements.
One action today: Revisit a recent outage and choose one preventive action with a named owner.
