"Doctrine describes the fundamental principles and concepts that shape the Nation's homeland security effort. It broadly tells us what planning is supposed to achieve, how it is structured and resourced, and how it is executed. Doctrine describes the systems, processes, intellectual underpinnings, and terminology that are the bedrock of homeland security planning. The doctrinal concepts and principles laid out here are consistent with planning systems already in place, or being considered for adoption. Specifically, this doctrine underpins and supports: (1) Homeland Security Presidential Directive-5 (HSPD-5) (2) Homeland Security Presidential Directive-8 (HSPD-8), Annex I (3) National Response Framework (NRF) (4) National Incident Management System (NIMS) (5) National Preparedness Guidelines (NPG) (6) National Strategy for Homeland Security (NSHS) (FEMA, (Interim) Integrated Planning System (IPS) for Homeland Security (Draft Version 2.3), July 3, 2008 copy, p. 2-1)
