Which term describes the management of an emergency incident involving multiple agencies with each having an assigned IC?

The term that describes the management of an emergency incident where multiple agencies are involved, each with its own assigned Incident Commander (IC), is "Unified Command." This approach is essential in situations where various organizations must collaborate to effectively manage the incident. Unified Command allows all the participating agencies to work together towards a common objective, ensuring that information is shared, decision-making is coordinated, and resources are utilized effectively.

This framework helps avoid confusion and redundancy, which can often occur in multi-agency responses. By participating in a Unified Command structure, each agency retains its autonomy while operating under a collective plan, fostering collaboration and improving overall incident management.

In contrast, the other terms such as "Unity of command," "Span of control," and "Incident command" either refer to principles that apply to single-entity command structures or specific aspects of the command hierarchy, making them less applicable to scenarios involving multiple organizations collaborating on an incident.
