Henri Fayol was a French mining engineer who developed 14 principles of management based on his experience managing a large mining company. The principles address topics such as division of labor, authority and responsibility, discipline, unity of command, and esprit de corps. Fayol also identified five primary functions of management: planning, organizing, commanding, coordinating, and controlling. The functions involve tasks such as looking ahead, structuring the organization, motivating employees, ensuring clear communication, and verifying performance. Fayol's principles and management functions provide guidance for effective organization and leadership.
