When an incident expands, the focus is on filling only the functions and positions necessary to effectively manage the situation. This approach aligns with the principles of the NIMS Incident Command System (ICS), which emphasizes a scalable and flexible organizational structure.

In an expanding incident, the goal is to efficiently allocate resources and personnel based on the specific needs of the situation, rather than overwhelming the incident response structure with unnecessary positions. By filling only essential roles, organizations can maintain operational efficiency, ensure clear lines of communication, and manage resources effectively, which is critical in dynamic and potentially chaotic environments.

This selective approach allows for a more streamlined command structure that can adapt and respond to the evolving needs of the incident, ensuring that the right people are in place to support the response efforts without adding to confusion or complexity. It ultimately contributes to a more effective incident management strategy by aligning personnel assignments with operational priorities.
