I have some experience as a manager, but not a lot (something short of a two years in the same company). I dislike the idea of standups both as a programmer and as a manager. They remind me too much of military drills: something performative, useless, only to keep new recruits busy.

The reason I think that is because it puts communication into a very simplified and regimented framework, so simple and unable to adequately answer the needs of the communicating parties that nobody actually uses it for the intended purpose. The actual communication happens between people who actually need to work on something, in the format that allows more freedom, with more aids, more prep time, perhaps over multiple sessions.

Sometimes, probably, as a manager, you have to work with a very low quality workforce, lacking motivation and simply avoiding doing any useful work as much as possible (eg. some overseas outsourced project that gets paid by an hour). In this case, standups become a soft punishment tool: something to verify that workers showed up to work, that they didn't lie about the progress made so far etc. You would still have to do the former part of the management, but now you also have this kindergarten-teacher style chore on top of it.
