Do these people prepare reports beforehand? Can they provide more detail?
Our executive meetings have 8 people and several months ago we all sent out a written summary beforehand because we were going to be short on time due to an outside guest. It made the meeting run way better and now we do it every time. not always perfectly, but its a big help.
i think sometimes people like to talk to prove that they are doing something. and sometimes they just like to talk.
aside from pre-written stuff, part of it is definitely just reigning people in. I run a regular meeting with 3 tech people and it could last all day if I let it. But I set the time and set the topics and if we go too far off, I just say it's enough, move on and we'll follow up on that another time. But it's important to take notes of that and follow up at least sometimes. Some of the time it probably won't even matter.
Also, to the extent that you can choose the time for the meeting, it might help, at least for your own sanity. If you can figure out when would be the best time for you to hold the meeting and also control your day, it might help you feel better. I went to a seminar last year called Taking Control of Your Workday. I can't say that I got that many specifics from it, but it helped to just kind of take a step back and psychologically refresh and re-orient. One of the biggest takeaways was to really think about how I was using my time and prioritizing. I tended to put all of the things that I needed to get done for other people at the beginning of the day, when I was probably at my best. Then by the time I could to the stuff that I really wanted to do, I was cranky and it was a cycle. So I figured out how to re-prioritize some things, especially the things that I really cared about.
It's possible that these kind of production meetings are more rigid, but it might be something to think about. I try to hold meetings in the afternoon now.
Anyway, that was kind of rambly and probably not specific enough.
