Organization is Based on the Incident Command System
Emergency responders use the Incident Command System (ICS) organization dictated by NIMS to help organize and manage incidents. CERTs use the same organization strategy. Using ICS for every incident helps hone and maintain skills as well as provides defined roles for CERT volunteers and professional responder alike. ICS helps to effectively coordinate efforts. The graphic below shows the structure and roles found in an ICS chart.
