Which of the following is NOT one of Fayol's five main duties?

Fayol's five main duties of management are planning, organizing, commanding, coordinating, and controlling. These elements are foundational concepts in the field of management and illustrate the various functions managers must perform to ensure an organization operates effectively.

Planning involves setting objectives and determining the best course of action to achieve them. Organizing is about arranging resources and tasks to implement the plan. Commanding, although less commonly referenced in modern terminology, relates to leading the team and ensuring that everyone understands their roles and tasks.

Coordination is crucial for ensuring that all parts of the organization are working together harmoniously to achieve the objectives, while control involves monitoring progress and making necessary adjustments to stay on track.

Delegation, while a vital management skill, is not explicitly listed as one of Fayol's five main duties. It is often considered a part of organizing and commanding, but does not stand alone as a distinct duty according to Fayol's framework. Therefore, the correct choice highlights the distinction between those duties directly outlined by Fayol and broader management concepts.
