What is used to manage the scenario when the number of sectors exceeds the span of control for an incident commander?

In incident management, particularly within the Incident Command System (ICS), the effective organization of resources is crucial for maintaining control and ensuring efficient operation. When the number of sectors exceeds an incident commander's span of control, it is essential to implement a structure that allows for better oversight and management of various operational components.

Branches are utilized to manage multiple divisions or sectors that fall under them. This organizational tier functions as a means to expand the command structure and ensure that the incident commander can maintain effective oversight without being overwhelmed. By using branches, the incident commander can delegate authority and responsibility to branch directors, who are then tasked with managing their respective divisions or sectors more directly.

This hierarchical approach is necessary because it facilitates communication and coordination among different groups involved in the incident while helping to keep the command function scalable. Essentially, branches help in maintaining control and effectiveness when facing complex incidents with many moving parts.
