Henri Fayol developed classical management theory in the early 20th century consisting of 5 elements: planning, organizing, commanding, coordinating, and controlling. Fayol's principles became popular in the US in the 1940s. Fayol believed in a strict hierarchy with centralized decision making and respect for authority. He also believed in fair remuneration to encourage a stable workforce and avoidance of high turnover rates. Employees should subordinate personal interests to those of the organization and be encouraged through fair supervision and initiative.
