What term is a NIMS guiding principle that states everyone involved in incident management reports to and takes direction from only one person?

• A. Unity of command
• B. Span of control
• C. Incident Command System
• D. Unified command

Answer: (A)

Unity of command means every person involved in incident management reports to and takes direction from only one supervisor. This creates a clear line of authority, prevents conflicting instructions, and improves accountability and coordination on the scene. Even when multiple agencies work together under Unified Command, each individual still has a single supervisor to answer to for their tasks, maintaining orderly operations. This is different from span of control, which is about how many subordinates a supervisor can manage, and from the broader concepts of the Incident Command System or Unified Command, which describe overall structure and multi-agency coordination rather than reporting relationships for individual personnel.
