Operations → Reliability
Postmortem
A written analysis of an incident that captures impact, causes, response, and follow-up actions.
Motivation
Postmortem is useful because it gives engineers a precise handle on a recurring problem: a written analysis of an incident that captures impact, causes, response, and follow-up actions.. It helps you decide what to pay attention to, what abstractions are available, and which tradeoffs matter in real systems.
Where it fits
Postmortem belongs to the Operations track, inside the Reliability layer. In the knowledge graph, this places it near concepts that explain the same level of abstraction and the neighboring ideas it depends on.
Mental model
Think of Postmortem as one piece of the larger computing map. It is easiest to understand when you ask two questions: what problem does it solve, and what assumptions does it make about the concepts below it?
Common mistakes
- Using Postmortem as a buzzword without understanding the problem it solves.
- Learning the definition in isolation instead of connecting it to nearby concepts.
