Always have a clear purpose; otherwise don't have a meeting.
Decide the issues for inclusion in the meeting and their relative priority: importance
and urgency - they are quite different and need treating in different ways.
Important matters do not necessarily need to be resolved quickly.
Urgent matters generally do not warrant a lot of discussion. Matters that are both
urgent and important are clearly serious priorities that need careful planning and
management.
You can avoid the pressure for 'Any Other Business' at the end of the meeting if you
circulate a draft agenda in advance of the meeting, and ask for any other items for
consideration.
