The Incident Command Team (ICT) is "a systematic tool used for the command, control, and coordination of emergency response" according to the United States Federal Highway Administration. A more detailed definition of an ICT according to the United States Center for Excellence in Disaster Management & Humanitarian Assistance is "a set of personnel, policies, procedures, facilities, and equipment, integrated into a common organizational structure designed to improve emergency response operations of all types and complexities. ICT is a subcomponent of the National Incident Management System (NIMS), as released by the U.S. Department of Homeland Security in 2004. The ICT is based upon a flexible, scalable response organization providing a common framework within which people can work together effectively. These people may be drawn from multiple agencies that do not routinely work together, and ICT is designed to give standard response and operation procedures to reduce the problems and potential for miscommunication on such incidents.
