I was on one project where there was a weekly two hour status meeting. The meetings generally started fifteen minutes late because she was futzing with her laptop and projector; her meetings also never ended on time.

If it takes a meeting organizer fifteen minutes to set up a computer and projector, set it up fifteen minutes prior to the start of the meeting. Be prepared to start the meeting on time and end the meeting on time; having an agenda helps with having an organized meeting. Holding people hostage while one sets up for the meeting demonstrates a lack of courtesy and respect for the meeting participants.

Her meetings were always a time vampire.
