A postmortem is a structured review conducted after an incident or completed project. It captures what happened, why it happened, what was done in response, and what the team intends to change. Well-run postmortems are blameless — focused on systems and processes rather than individuals.
A postmortem is distinct from a status update. Status updates describe ongoing work. Postmortems analyze closed events. The value of a postmortem comes from its commitment to record-level honesty about decisions and failures, including ones that look bad in hindsight.
Postmortems become useful institutional memory only when they are stored where future engineers can find them. A postmortem written in a Google Doc that no one ever opens again is not a postmortem — it is therapy.
Why Postmortem Matters for Distributed Teams
Postmortems are how teams convert incidents into knowledge. Without them, the same failure recurs every six months. With them, the team accumulates a queryable history of how it has learned.
Distributed teams need postmortems even more than co-located teams, because the verbal lore that often replaces them in co-located settings does not survive timezone boundaries.
