> I've been to standup meetings in close to a dozen different companies, ranging from the smallest startup to some of the biggest tech companies and never have I ever seen a standup meeting end on time. NEVER. I don't think it actually happens. What I have seen is the meeting go on for half an hour to an hour, boring everyone out of their minds. Sometimes this even involved multiple teams whose work barely intersected at all. The other team's work status was a pure waste of time for anyone not on that team.

A stand-up shouldn't take more than a couple of minutes per person, at the most. The thing that seems to help the most with this is to set aside a section of the whiteboard for the "Parking Lot". If the discussion starts getting off-topic or taking too long, the leader says "let's put this in the parking lot for now", makes a note of the topic on the whiteboard, and you move on to the next person. After the main part of the stand-up meeting is done, the Parking Lot is addressed, but only people who want to discuss it (or are needed for such discussion) need to stay.
