The Chain Of Command
The chain of command is a common term for the vertical reporting an authority relationship in organization chart. The chain of command is the unbroken line of authority that ultimately links each individual with the top organizational position through a managerial position at each successive layer in between.
The concept of chain of command stems from two basic principles: unity of command and the scalar principle. Unity of command means that an individual should have only one boss at any given point in time. The scalar principle states that there should be a clear line of authority from position of ultimate authority at the top to every individual in the organization.
