Which statement correctly describes how to manage span of control using the modular concept?

Managing span of control using the modular concept in the Incident Command System (ICS) is accomplished by organizing resources into Teams, Divisions, Groups, Branches, or Sections.

By enabling the formation of modular elements based on the specific requirements of the incident, ICS facilitates effective span of control across all levels of incident management. For example, in a large wildfire incident, the incident may be divided into geographical Divisions to manage different sections of the fire or functional Groups to address specific tasks such as evacuation or logistics. 

From the perspective of incident personnel, the ability to manage span of control effectively is crucial for maintaining operational efficiency and responder safety. Personnel operating within a well-structured ICS organization can focus on their assigned tasks with clear expectations and accountability.

The modular organization also supports the principle of unity of command, ensuring that each individual reports to only one supervisor. This clarity in the reporting structure enhances coordination among various teams and agencies involved in the incident.
