A chairman is the presiding officer of a meeting, organization, committee, or other deliberative body. It is his or her responsibility to determine the agenda for each meeting, and ensure that everyone operates in an efficient manner and in accordance with any previously agreed rules. He or she may also be entrusted with various other executive powers. Chairman also means chair manager and hence is shortened to chairman, However, in order to avoid sexist assumptions, the position is nowadays sometimes called chairperson or simply the chair. Alternatively, the title of chairwoman may be used if the incumbent is female.
