First, a points on in-person meetings : I'm an introvert. I like people, but they tire me, and the more people, the faster my brain shut down. If I have a 3 hour meeting each Tuesday, my productivity each Tuesday will be between 1 and 3 hours max, even when I'm super involved and own the product. Moreover: - I need time to internalize what I learned from other people. If I go to work too fast, I probably won't have understood what was said and loose even more time. Since I want to get back to work after long meetings, and since my brain is dead, it lead to really poor decisions (nowadays I just scrap the code entirely and start from scratch rather than try to salvage). - Online meetings feel worse. When too many people are involved, you can't just be a passive listener for 45+ minutes. But if you do other work, you might miss information. - okay meeting size is four to seven , if you all have a basic knowledge of what will be discussed. Can be pushed if the team is tight and not too much junior. - best meeting size is two to three. All other sizes, you'd rather do a presentation with some interactivity and with the support available to everyone at the end.
