What term describes the function associated with managing an office or organization?

The term that best describes the function associated with managing an office or organization is administration. Administration involves the processes, systems, and practices that ensure the efficient and effective functioning of an organization. It encompasses planning, organizing, staffing, directing, and controlling the resources (both human and material) of an office or organization to achieve its objectives.

Administration is critical because it lays the foundation for how an organization operates, ensuring that various departments work cohesively towards common goals. This function is distinct from management, which often focuses more on the strategic direction and decision-making within an organization, and from leadership, which emphasizes inspiring and guiding individuals or teams. Though operations can also relate to management processes, it primarily pertains to the day-to-day activities involved in running the organization. Consequently, administration serves as the bedrock of organized operations, making it the most appropriate term in this context.
