Which of the following does not belong to Fayol's list of management duties?

Fayol's management duties include five primary functions: planning, organizing, commanding, coordinating, and controlling. Each of these functions addresses specific aspects of management in an organization. While communication plays a crucial role in all management processes, it is not explicitly identified as one of the core managerial functions outlined by Fayol.

Coordination is indeed part of his duties and involves synchronizing activities within the organization to ensure that they work together effectively. Forecasting is related to planning, as it entails predicting future conditions and making plans accordingly. Staffing, while not one of Fayol's core functions, is commonly associated with organizing, which involves establishing roles and responsibilities within the organization.

Therefore, communication is the correct choice, as it is an essential skill that underpins all management activities but is not one of the core managerial duties that Fayol specified.
