There are three levels of homeland security planning Strategic, Operational and Tactical. Strategic. At this level, executive decision makers determine strategic homeland security objectives. From these objectives, they develop overall, high-level guidance for planners. Using this guidance, planners develop their strategic plans designed to apply resources to accomplish these objectives. These are the widest scoped, least detailed plans in the planning hierarchy. Operational. Strategic plans provide guidance for operational planning. Operational objectives support strategic objectives, sequence events, initiate action and apply resources to begin and sustain activities. It is at this level that operational planning is conducted and sustained across the homeland security operational continuum (e.g., Prevent, Protect, Respond and Recover). Plans written at this level include concept of operations plans (CONPLAN) and organizational operations plans (OPLAN). These plans are more narrowly scoped and more detailed than strategic plans. Tactical. Tactical plans are more focused and detailed than operational plans. Activities are focused on the arrangement of resources in relation to each other and to the threat or natural disaster. Tactical plans are developed to support the objectives of operational plans. The IPS is not intended to replace NIMS or the Incident Command System (ICS).
