Everyone who has a stake in the outcome of a meeting tries to promote an agenda and most of this book discusses how the managers and organizers can have a successful event. We should not be surprised, however, when members of the public represent a special interest or express points of view that are contrary to our own or appear to challenge our leadership. Thoughtful, enthusiastic, and vocal attendees, even if they tend to get off the track we have laid so carefully, should not be considered barriers to successful meetings. Chairpeople, facilitators, and discussion leaders can deal with problem situations if they maintain a sense of humor, show goodwill, and adhere to the democratic process.
