A meeting is a democratic form of communication which usually depends on a degree of agreement for it to be successful. The chief function of a chair is to assist the meeting to achieve the required degree of agreement. To do this, the chair must see that all eligible participants have equal opportunity. This, in turn, may mean that the chair must be prepared to curb some speakers, for example, the more vociferous, while encouraging others, such as the more timid. The chair will strive to eliminate all interferences with this chief function of seeking agreement, such as private discussions, uncomfortable conditions and lack of order. An effectively chaired meeting will steer the meeting to work through agenda items.
