What organization defines the roles, responsibilities and standard operating procedures used to manage emergency operations?

• A. NIMS
• B. FEMA IMS (Federal emergency management agency incident management system)
• C. DHS
• D. CDC

Answer: (B)

Emergency operations rely on a single, scalable system that standardizes who does what and how things get done. The organization responsible for defining those roles, responsibilities, and standard operating procedures to manage an incident is FEMA's Incident Management System. It lays out the command structure, the key positions (like Incident Commander and staff roles), and the procedures for incident action planning, resource management, and communications. This IMS is part of the National Incident Management System, which provides the nationwide framework, with FEMA's system serving as the concrete implementation used to run operations across agencies. DHS and CDC are separate agencies with their own missions and do not define the universal incident management framework.
