I recently worked an outage for a client and needed a quick template to write up my findings. It might be a little TMI, but Atlassian’s template covered a broad range of use cases and I found everything mostly relevant for the “lighter” issue I was reviewing: https://www.atlassian.com/incident-management/postmortem/templates
I created a quick google doc template of this here: https://docs.google.com/document/d/1dhyBzh1qUdhhdSMkov-CY_6YvV5ZDD6ZGyVnMNs9RPI/edit?usp=sharing
I especially liked the refresher on “root cause identification” via the 5 whys. Tracing the exposed problem back to a root cause is something I feel too many teams miss out on. The general idea is to start with the problem and loop to asking why that happened until you get to the root of the issue. (sidenote: It’s incredibly important to separate the issue from the people associated with the issue to maintain a blameless and productive environment.) More background on the 5 whys on wikipedia.
