Which management concept states that every firefighter answers to only one supervisor?

• A. Chain of Command
• B. Span of Control
• C. Unity of Command
• D. Delegation

Answer: (C)

Unity of Command is the principle that each firefighter reports to a single supervisor and receives all directions from that one person. This creates a clear line of authority on the fireground, reduces the chance of conflicting orders, and makes accountability straightforward. Even within a larger chain of command, the key idea is that a person has one direct supervisor to turn to for assignments, priorities, and feedback.

Think of it this way: the chain of command sets up the overall ladder of authority, ensuring there’s a defined path for orders from the top down. Span of control, on the other hand, concerns how many people a supervisor can effectively manage at once. Delegation is about transferring authority to others to perform tasks, not about who a subordinate reports to. But Unity of Command specifically addresses the reporting relationship, ensuring no one answers to two bosses or receives competing instructions.
