Which principle is important for establishing clear lines of authority in an organization?

The principle that is most important for establishing clear lines of authority in an organization is the Chain of Command. This principle outlines the hierarchical structure within the organization, detailing how authority and responsibility flow from the top levels of management down to the lower levels. By defining the chain of command, each member of the organization understands whom to report to, as well as their own authority and responsibilities.

This clarity helps prevent confusion and ensures that instructions and commands are followed efficiently. It also establishes a framework for accountability, as individuals know their position within the hierarchy and what is expected of them in relation to others.

The other concepts, while relevant to organizational effectiveness, serve different purposes. Unity of Command emphasizes that each employee should report to only one supervisor to avoid conflicting demands. Delegation involves assigning responsibilities to subordinates, which can empower employees but does not inherently establish authority lines. Span of Control relates to the number of subordinates a manager can effectively supervise and is more about operational management than clarifying authority.
