I guess are we talking the pilot or mechanic? And is the mechanic working on a plane that is expected to function completely differently year to year?
I mean if I’m running sql then yes I expect someone with experience in sql to be able to onboard quickly to be able to execute sql queries.
Isn't that the purpose of good documentation?
Imagine a plane pilot with lot of experience taking a new job, does they need one year to train before taking passengers on flight?
