Which principle focuses on maintaining a clear chain of authority and reducing conflicting directives?

• A. Division of Labor
• B. Unity of Command
• C. Communications
• D. Span of Control

Answer: (B)

Unity of Command is the idea that each person on the scene reports to one supervisor, creating a single, clear chain of authority. This minimizes conflicting directives because only one set of orders guides a task, which reduces confusion, enhances coordination, and makes accountability straightforward if safety or performance issues arise. In a fire department setting, a firefighter would receive directions from a single incident commander or sector supervisor, ensuring consistent, rapid decision-making during critical operations. Division of Labor organizes work by tasks or specialties, not reporting lines. Span of Control deals with how many subordinates a supervisor can effectively oversee, which affects supervision workload rather than the existence of one command channel. Communications is about how information is shared, which is important but does not alone establish a single command structure.
