Effective organizational communication serves as a critical mechanism that enables managers to execute fundamental management functions. Which of the following functions directly rely on effective communication?
I. Leading (Directing & Motivating)
II. Controlling (Monitoring & Evaluating Performance)
III. Power (Positional & Personal Influence)

In management theory, communication is the primary medium through which managers perform the core functions of management (Planning, Organizing, Leading, and Controlling). Role in Leading (Statement I): Managers use communication to direct employees, articulate organizational goals, motivate team members, resolve conflicts, and build trust. Role in Controlling (Statement II): Communication is essential to transmit performance standards, collect feedback, evaluate progress, and convey corrective actions when deviations occur. Distinction Regarding Power (Statement III): Power is a source of influence or a relational dynamic within an organization, not a basic managerial function. While communication can be used to exercise power, power itself is categorized under organizational dynamics rather than fundamental managerial functions.
