Which of the following is NOT one of Henry Fayol's original management principles?

Henry Fayol's management principles are foundational to classical management theory, and he originally identified fourteen principles that guide effective management processes. Among these principles, planning, staffing, and leading are indeed integral parts of Fayol's framework.

Planning is recognized as a crucial management function, involving the formulation of objectives and determining the best course of action to achieve those objectives. Staffing pertains to the organization and allocation of human resources, ensuring that the right people are in the right positions. Leading involves influencing and guiding others toward achieving the organizational goals.

Motivation, while a significant aspect of management, particularly in the context of leadership and employee engagement, was not explicitly listed as one of Fayol's original principles. Fayol’s principles focused more on the structure and function of management rather than the psychological aspects of motivating employees.

Thus, motivation is correct as the option that is not part of Fayol's original principles, as it encompasses broader theories and approaches that evolved later in management thought, separate from Fayol's contributions.
