Fayol developed 14 principles of management based on his experience as a mining engineer and manager. Some of the key principles included division of work, where specialization increases efficiency; authority and responsibility, where managers must have authority to give orders but also be responsible; and unity of command and direction, where employees should receive instructions from one supervisor and teams should work under one manager. Other principles focused on discipline, fair remuneration, order, stability of personnel, and initiative. Overall, Fayol's principles aimed to provide structure and guidelines to effectively manage organizations.
