Which of the following statements best describes a primary feature of the Incident Command System?

• A. ICS is a standardized hierarchy for incident management with roles (Command, Operations, Planning, Logistics, Finance/Administration).
• B. ICS is a financial accounting system.
• C. ICS is a communication protocol with no roles.
• D. ICS refers to infection control standards in hospitals.

Answer: (A)

Incident Command System is built around a standardized, scalable management structure for incidents. The primary feature is a clear hierarchy with defined functional roles: Command oversees the incident, Operations directs tactical field activities, Planning gathers information and develops action plans, Logistics provides personnel, facilities, and supplies, and Finance/Administration handles costs and contracts. This structure enables coordinated decision-making, clear lines of authority, and the ability to expand or adapt as the incident grows or changes. It’s not a financial accounting system, not a protocol without roles, and not infection control standards—the other options describe functions outside what ICS is designed to do.
