The core concepts and principles of the Multi-Agency Coordination System as taught by DHS (and as defined in the NIMS Document) incorporate the following components: (1) A multi-agency coordination system is a combination of facilities, equipment, personnel, procedures, and communications integrated into a common system with responsibility for coordinating and supporting domestic incident management activities. (2) The primary functions of multi-agency coordination systems are to support incident management policies and priorities, facilitate logistics support and resource tracking, inform resource allocation decisions using incident management priorities, coordinate incident management related information, and coordinate interagency and intergovernmental issues regarding incident management policies, priorities, and strategies. (3) A typical multi-agency coordination system may contain one or several Emergency Operations Centers (EOCs). A typical multi-agency coordination system may contact numerous Department Operations Center (DOCs). Depending upon the type and location of the emergency/disaster various command elements (i.e. area commands, unified command or the incident commander) will have to coordinate activities within an established multiagency coordination system. Training dealing with the NIMS multi-agency coordination system shall describe to participants the components of a multi-agency coordination system and establish relationships between all elements of the system. It shall also increase the participant's knowledge of NIMS relevant to the multi-agency coordination system. It shall increase the participant's knowledge of the integrated nature of emergency management throughout the nation and advocate the adoption of the guidelines established in the NIMS document. The training shall contain specific disaster/emergency related examples that relate to multi-agency coordination systems at the local, state and federal levels of government.
