For what types and sizes of incident is the Incident Management System designed?

• A. Multi-agency only, medium or large size
• B. Multi-agency only, any size
• C. Single agency only, large size
• D. All types and sizes

Answer: (D)

ICS is built to be scalable and usable for any incident, no matter the type, size, or number of agencies involved. Its modular structure lets you start with the basic command framework for a small, single-agency event and expand to handle large, multiagency operations without changing the overall system. That flexibility is why all types and sizes is the best choice. The other options impose limits that ICS is explicitly designed to avoid, such as restricting to multiagency or to larger incidents, which would not reflect its all-hazards, all-sizes purpose.
