What do I write down before going on holiday?
ChatGPT
The three things that break, how to tell which one it is, and who to call when it is none of them. Architecture diagrams are pleasant; runbooks are what get used at two in the morning.

How do I transfer ownership of a service properly?
ChatGPT
Have the new owner run the next two deploys and the next incident while you watch. Documents transfer facts, not judgement, and judgement is most of what ownership is.

How long does this usually take in practice?
ChatGPT
An afternoon to do it properly the first time, then minutes when it recurs. Most of the first afternoon goes into discovering which of the defaults do not match your situation.
