Henry Fayol was a pioneer in management theory who introduced 14 general principles of management that can be applied to all levels and departments of an organization. The principles include division of work, authority and responsibility, discipline, unity of command, unity of direction, subordination of individual interests, remuneration, centralization, scalar chain, order, equity, stability of personnel, initiative, and esprit de corps. Fayol's theories helped establish the foundations of modern management practice.
