roles of chairman of the board of directors
The chairman (also chairperson, chairwoman or chair) is the highest officer of an organized group such as a board, a committee, or a deliberative assembly. The person holding the office is typically elected or appointed by the members of the group. The chairman presides over meetings of the assembled group and conducts its business in an orderly fashion. When the group is not in session, the officer's duties often include acting as its head, its representative to the outside world and its spokesperson. In some organizations, this position is also called president (or other title), in others, where a board appoints a president (or other title), the two different terms are used for distinctly different positions.
