Because as far as I can see, they were just cargo-culted from around-the-clock operations and single-shift development has no subject at all that fits the format. But people keep doing them, so I keep being interested on what do they gain from it?
Something I saw that was useful was ~50-75% of the people pass on sharing something and the other ~25-50% mention something that surprised them or something they are stuck on in the past 24hrs. Then other people will either be less surprised or swing by their desk to help get them un-stuck.
It's a way to increase the number of "watercooler" style interactions where one person can help someone because they happen to have a tiny bit of knowledge or expertise that can help
We just want to know if anyone's blocked on anything, which can either be quickly sorted in 10s of conversation or people can agree to chat one on one after the call. It's just some basic coordination at a time everyone agrees to be present.
I disagree, standup is not just for discussing blockers.
Summarizing what problems you're solving often serves as a trigger for further conversations, e. g. "I did something similar a few weeks ago, let's talk after the standup".
It's not mutually exclusive. But people work at different times, and need focus, and won't all keep up with a scrolling chat thread. Having a simple 15 minute call when everyone's there solves all that.
