Final answer:
The chain of command is an element of organizational structure that deals with position-based reporting lines.
Step-by-step explanation:
The element of organizational structure that deals with position-based reporting lines is known as the chain of command.
The chain of command refers to the hierarchy or line of authority within an organization, where each position reports to a higher-level position. It establishes who is responsible for giving orders and who is accountable for carrying them out.
For example, in a traditional hierarchical structure, a CEO has authority over a group of vice presidents, who in turn have authority over managers, and so on. This creates a clear reporting structure and helps to streamline communication and decision-making.
