Our old project manager mandated we must have daily stand-ups.
They were always at least five minutes late for what should have been a five minute stand up because they knew we'd have to wait for them.
I managed to get team agreement we start no later then 2 minutes past, no matter who isn't there, management included, no judgement for late comers but the meeting is starting as we have work to get on with.
Suddenly said project manager started showing up on time. Who knew?
