A meeting that does not result in 1) a decision 2) action items or 3) information distribution is a waste of time. As a team, meetings are necessary to get "on the same page". It is true, sometimes in a meeting we think, "This could have been done with email". And other times when there is an email thread with 20+ responses, we think "A meeting would have solved this faster" It is not always easy to plumb the depths of a topic to decide beforehand.
