Which directive establishes a comprehensive national incident management system for efficient government collaboration?

The directive that establishes a comprehensive national incident management system for efficient government collaboration is Homeland Security Presidential Directive-5. This directive was issued to ensure a coordinated response to domestic incidents, regardless of their nature. It formalizes the National Incident Management System (NIMS), which provides a standardized approach to incident management across various jurisdictions and disciplines.

This structure fosters effective communication and collaboration among federal, state, local, tribal, and territorial authorities during incidents, leading to better resource allocation and operational efficiency. By requiring the implementation of NIMS, the directive helps create a unified and organized response framework, ensuring that all responding agencies can work together seamlessly in crisis situations.

Other options reference important aspects of national security and emergency management but do not specifically focus on establishing a comprehensive national incident management system as directly as Homeland Security Presidential Directive-5 does. For instance, Homeland Security Presidential Directive-3 pertains more to the security of critical infrastructure, while Directive-8 deals with national preparedness policies rather than incident management itself. The Federal Response Framework outlines a coordinated response, but it is based on principles set forth in the National Incident Management System established by Directive-5.
