Which principle involves a clear chain of command in an organization?

The principle that involves a clear chain of command in an organization is Unity of Command. This principle asserts that each employee should report to only one supervisor at a time. This structure helps to eliminate confusion and conflict over authority, ensuring that instructions are relayed clearly and that accountability is effectively established. By adhering to this principle, organizations can maintain order and clarity, allowing for better coordination and compliance with directives throughout the hierarchy.

While other principles such as Scalar Chain also pertain to organizational structure, Unity of Command specifically emphasizes the importance of having a single reporting line for each employee. Scalar Chain, on the other hand, focuses more broadly on the hierarchy levels within an organization, suggesting that communication should flow through established channels of authority as determined by the organization's structure.
