Questions For Postmortems
May 05, 2020
Today I learned more questions to ask during a postmortem.
This afternoon I sat in on a postmortem for a production issue. This was my first postmortem with Ro since our site-reliability team had revamped the process.
Included in this process were two questions I am quite familiar with:
- What went well?
- What could be improved?
There were two other questions that I have not seen asked before:
- Where did we get lucky?
- What were we wrong about?
I really like these latter questions as they force the team to acknowledge the fragility of certain systems - to “turn over the rock” as we say at Ro - and to reconsider our understanding of systems, user behavior, etc.
