I know a guy that can run those meetings.

He meets with all the stake holders, determines their desired outcomes, makes sure they are all prepped.

Starts the meeting, sets the goals and the ground rules.

As soon as the meeting exit criteria are met (either another meeting, more homework or a decision has been made) the meeting is over. Done.

Most meetings with this guy lasted 12-17 minutes.

His job was toilsome, but he saved everyone else. I am getting teary eyed just thinking about it.
