Hand out general announcements. Have these printed and ready to hand out at the meeting. Briefly refer to the list and point out key information only. A long list of announcements at the start of a meeting tends to put people in a passive, sleepy mood and items are forgotten. People also resent spending valuable meeting time on announcements that could have been made by memo.
Endings are Important.
End on time. Do not go overtime unless all agree that it would be a valuable thing to do. If important content is not covered, it may be advisable to hold a second brief meeting. Having done this once, team members soon learn the importance of staying on topic and moving through the agenda efficiently. Avoid shouting instructions and reminders as people are going out the door.
