Which principle states it is not about who is in charge, but about who is in charge of what?

• A. Common Terminology
• B. Unified Command
• C. Integrated Communications
• D. Modular Organization

Answer: (B)

Unified Command means leaders from all the major involved agencies share command authority, focusing on who is responsible for what rather than who is in charge personally. In this approach, representatives from each agency participate in a single, coordinated command structure, agreeing on common objectives, approving the Incident Action Plan, and directing resources together. This shared authority ensures clear roles for functional areas such as operations, planning, logistics, and finance, and prevents one agency from unilaterally driving the response. It’s especially important in incidents crossing jurisdictions or requiring multi-agency coordination, because it aligns all parties toward a single set of goals and a coordinated strategy.

The other concepts address different parts of incident management: standardized terminology, interoperable communications, and a flexible, scalable organization. They’re important for smooth operation, but they don’t encapsulate the idea of multiple agencies jointly commanding with respect to who handles which aspects of the response.
