The Incident Command System (ICS) is a standardized approach to incident management that is used by first responders in the United States. ICS was originally developed in Southern California in the 1970s to coordinate response to wildfires. It is a flexible, scalable system that divides incident response activities into five functions or sections - Command, Operations, Logistics, Planning/Intelligence, and Administration/Finance. Each section is responsible for a particular aspect of response such as managing resources, conducting tactical operations, planning, and financial management. The system allows response efforts to expand or contract depending on the needs of the incident.
