The NISM describes how FEMA NRCS at the NRCC supports FEMA incident operations. It includes definitions and descriptions of roles and responsibilities, functions, and organizational structures for those conducting FEMA incident support duties.
The NISM forms the basis from which FEMA personnel plan and execute their assigned missions. It also serves as the basis for developing related guidance (procedures, handbooks, incident guides, training materials, etc.).
Finally, it also discusses how NRCS procedures are relevant to all personnel (FEMA, other Federal agencies (OFAs), NGOs, and the private sector) who are either assigned to, or coordinating with, the NRCS.
