I'll add that what a lot of non-developers seem to think is documentation is not actually worth very much. For instance, a 2 hour recording of a zoom meeting tagged only with a date and general topic is worth so much less than a searchable text guide on the same topic. Recording a meeting is not documentation! Especially if it's not tagged properly and made available to the people who need it. It's also impossible to update a meeting recording of course so it's guaranteed to be out of date after enough time passes, requiring that meeting to be held and recorded again.
Other things that I see treated as documentation when they're not: slack messages, uncommented code ("self-documenting" code exists, but it's much rarer than management seems to insist), vague jira tickets, some guy who worked on the app 5 years ago and is happy to answer questions even though he's in a new role now, etc.
This is one thing that has always bothered me! A lot of clients ask if I have checked the documentation when I have a very specific question. The documentation however, is just a drive of a bunch of recorded meetings with no tags or transcripts. Am I really supposed to linearly look through tens of hours of recorded meetings to see of the detail might have been mentioned on one of those?
If they are clients or people responsible for any kind of budget, just phrase it as a business offer: I can watch through the 89 hours of relevant documentation in 89 hours for $165 an hour. Pricing fixed if accepted within 2 weeks of offering date.
I have found that the post meeting notes written by at least two persons then consolidated and improved by others really do help. Recordings while better than nothing would have to have transcripts in order to be usable. Hard to watch hour long recording searching for the relevant 5mins.
