Definition

A standardized, scalable on‑scene organizational framework that establishes common terminology, defined roles (incident commander, operations, logistics, planning, finance), unity of command, span of control limits, and incident action planning to coordinate multiagency emergency response operations; it prescribes how to organize and communicate, not specific tactical choices.
