is the presiding officer of a meeting, organization or committee. It is his or her responsibility to outline the agenda of the group, and ensure that everyone operates in an efficient manner. He or she may also be entrusted with various other executive
powers. In order to avoid sexist assumptions, the position is nowadays more often called chairperson
or simply the chair
. Alternatively, the title of "chairwoman" may be used if the incumbent is female.
In China the title of "Chairman" is often used interchangeably with that of president (ex: Chairman Mao).
