The Chairman's role will depend upon the type of Committee and especially upon the method of discussion used by the committee. If a meeting is of the free, leaderless type, the Chairman will have little authority except to preside and keep order. If there is disagreement among committee members on some controversial issue, it may sometimes be helpful for the Chairman to intervene by giving his own views. When a latecomer does arrive he will probably be expecting some reproof, and the Chairman can deal more effectively with the situation in some other way. Chairman can tactfully break in and ask another member for his views must depend upon how long the talkative person can speak without pausing for breath. If a member is silent through lack of experience, the Chairman will be well advised to leave him alone for the time being.
