A Chairman of the Board is the highest-ranking officer in a corporation and presides over the meetings of the board of directors. This role may or may not possess the most executive authority within the firm. In some cases, the Chairman also carries the title of Chief Executive Officer (CEO), who is the principal executive of the corporation.
A Chief Executive Officer (CEO) is the highest-ranking executive in a company or organization, responsible for making major corporate decisions, managing overall operations and resources, and acting as the main point of communication between the board of directors and corporate operations.
The President is the highest-ranking officer in a corporation after the Chairman of the Board, unless the title of Chief Executive Officer (CEO) is used. In that case, the CEO can outrank the President. The President is appointed by the Board of Directors and usually reports directly to them.
