The Incident Command System (ICS) is a standardized, on-scene, all-hazard incident management concept. It is a management protocol originally designed for emergency management agencies and later federalized. ICS 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 ICS is designed to give standard response and operation procedures to reduce the problems and potential for miscommunication on such incidents. ICS has been summarized as a "first-on-scene" structure, where the first responder on a scene has charge of the scene until the incident is resolved or the initial responder transitions incident command to an arriving, more-qualified individual.
