Meetings can be dramatically shorter and more effective by thinking of the agenda as a map—not a list, having a clear product and reducing weak language.
I have borrowed this from a friend – Bill Hoogterp
Imagine your goal is the top of the mountain where you want the group to go. Everyone has to agree on your goal. That goal has to be fixed, it does not change and your job as a leader is to get the group there.
Now imagine the path up the mountain is your strategy. That is flexible. There can be many different paths that reach the top of the mountain, which is the better one or best one for now?
Be firm on the goal, flexible on the strategy. You want your group, your employees and colleagues to improve your strategy and come up with a better path whenever they can.
...more to come on effective meetings...
