Henry Fayol was a French mining engineer and director of mines who is considered one of the most influential contributors to modern management theory. He proposed 14 principles of management based on his experience, including division of work, authority and responsibility, discipline, and unity of command and direction. The principle of division of work involves specializing tasks to increase efficiency. Authority and responsibility go hand in hand, as whoever has authority also has responsibility. Discipline requires respect for rules to encourage cooperation. Unity of command means each employee has one supervisor, and unity of direction means coordinating groups with the same goals.
