Henri Fayol's 14 principles of management serve as essential guidelines for organizational decision-making and practices, based on observations and analyses of managerial experiences. Key principles include division of work for efficiency, authority and responsibility correlation, discipline for smooth operations, unity of command to avoid confusion, and subordination of individual interests to organizational goals. Other principles address remuneration for motivation, centralization versus decentralization in decision-making, and maintaining a clear scalar chain to ensure effective communication and order within the organizational structure.
