A daily stand up is good for some dispersed teams, or close-knit teams that for some reason (forming, norming?) have not developed the ability to communicate effectively, or get a feel in real-time what their colleagues are doing. Any higher-order stuff should be dispersed by a team leader or senior team member - and that can be done 'as, and when, needed'. Does this require a mandatory daily stand-up? On some occasions, I have reduced the daily stand-up from 30 mins (yes, I know) to 20, then 15...etc and it's common for them to reach 0 without any loss of knowledge transfer because the team members have started to communicate effectively by other means. Granted, the pandemic has changed the nature of the communications challenge a bit. I am happy to see teams having a daily stand-up because they need them. I take more notice when teams have a daily stand-up because they have been told they should have one.
