" All active participants in a meeting can instinctively sense progress, and when progress isn’t being made, they get cranky and start looking for the exit. A referee’s job is to shape the meeting to meet the requirements of the agenda and the expectations of the participants. Style and execution vary wildly from referee to referee, but the defining characteristics are the perceptions of the meeting participants. A good referee not only makes sure the majority of the attendees believe progress is being made, but they’re aware of anyone who doesn’t believe that progress is being made at any given moment. And they’re looking for one thing . . . people checked out. "
