What term refers to the formal line of authority within an organization?

The term that refers to the formal line of authority within an organization is "chain of command." This concept outlines the structured pathway of communication and responsibility that defines who is in charge, who reports to whom, and how decisions are made within the organization. In the context of fire service, understanding the chain of command is crucial because it ensures that operations are conducted efficiently and safely, with clear lines of authority established for decision making and accountability. This hierarchical structure helps maintain order during emergencies, facilitates clear communication among personnel, and ensures that all team members understand their roles and responsibilities.

"Span of control" pertains to the number of subordinates that a supervisor can effectively manage, which is a different concept and relates to the breadth of an individual's supervisory responsibilities. "Organizational hierarchy" refers to the arrangement of roles and responsibilities within an organization but does not specifically imply the formal authority and decision-making structure inherent in the chain of command. An "accountability system" encompasses the mechanisms in place to hold individuals responsible for their actions or decisions but does not directly represent the formal lines of authority that guide organizational structure.
