I want to play the devil's advocate here, but one motivation for meetings generally, is a memory, in some managers head, of a three million dollar disaster that occured strictly because some trivial piece of understanding had not passed from one group to another. It was a piece of knowledge that the first team considered so obvious that it didn't even bear stating. But the second team had no idea.

"Jim", the CEO said to the manager after that incident, "you're a good person, so we want you to stay here. But if we lose another seven figures because the right hand doesn't know what the left hand is doing on your staff again, it's over."

But there are such better ways of solving that problem!!! Yes, probably, but we have to know that's a problem we're trying to solve.
