Assuming you have one at all, what time do you have your daily stand up meeting? Are there reasons why you have it at that time? Do you like having it at that time?
09:30 on my team. Between multiple project teams I believe our dailies are between 9:00, maybe slightly before too, and 10:00. Can also depend on the customer if we're part of their development team. I believe not all teams have them every day.
It's a good time for me because I sometimes begin at around 9:00.
At 9:00 begins our central working hours where we're expected to be working. And I think that's late enough for the late starters. So I like where we're at.
I think it's good to have it "early" rather than late. If you struggled the previous day it's a good point of fresh start and possible discussion or follow-up support. It's also where you have [to make] a plan for the day.
