This document provides an overview of the Incident Command System (ICS) and how it coordinates with response clusters in the Philippines. The ICS standardizes incident management for all hazards and allows different agencies to work together. It is mandated by law. An Incident Management Team (IMT) is formed for each incident, led by an Incident Commander. Response clusters such as health, protection, and logistics provide resources. The IMT tactically manages resources on-scene while clusters support from operations centers. Coordination occurs between clusters and the IMT through the emergency operations center to ensure an effective, interoperable response.
