Chief Executive (CE) or Chief Executive Officer (CEO). A key role of the board is to appoint the Chief Executive Officer and to ensure the CEO manages the organisation in accordance with the agreed objectives (strategic plan or other accountability documents). The Chief Executive is answerable to the board. When a Chief Executive becomes a director of the board, and can therefore take part in voting, they are called a Managing-Director or M-D. Other names for the operational head of an entity may be Secretary, Director-General, Principal, or Vice Chancellor.
