Speaking as a manager who at least _thinks_ I run stand ups well, I have them run for 5-10 minutes max for 5 people and treat them as an update so that I can run interference on any “status updates” other parts of the company demand across a day, and as the time for the team to tell me what problems I need to go fix for the team to be productive.

I usually leave a standup with a list of 1-3 people I need to go talk to, to either move the code through bureaucratic processes, or an actual decision to make on which projects we’ll take on based on information found while engineering.

That said I also don’t care if my people say they have nothing of note and skip the meeting

The only particularly useful standup I've been in is when our VP was joining to see if we needed any quick escalations each day for about a week

Everything else is fun for memorizing what everyone's doing so I can respond immediately to random questions, but the value is questionable. Everyone else on my team would be better off if I didn't know everything off hand, and instead relied on the proper sources of truth
