Span of control within ICS is achieved by organizing resources into which of the following?

Span of control within the Incident Command System (ICS) refers to the number of individuals or resources that one supervisor can effectively manage. Achieving an optimal span of control is crucial for maintaining effective leadership and ensuring clear communication during emergency management operations.

The correct choice emphasizes that organizational resources can be grouped into teams, divisions, groups, branches, or sections. Each of these structures allows for a systematic hierarchy that supports both management and coordination within an incident response. By utilizing these various forms of organization, ICS can ensure that supervisors have an appropriate number of direct reports, which typically aligns with the ideal range of three to seven individuals, enhancing both oversight and operational efficiency.

In contrast, the other selections are too narrow. For instance, units, branches, and departments alone do not encapsulate the full range of organizational structures available within ICS. Focusing only on one specific type of grouping can lead to inefficiencies or overwhelm supervisors, as they may be unable to effectively manage too many resources under a single category. The flexibility in using different group types allows for adaptation based on the incident's needs, making this option the most comprehensive and effective for achieving proper span of control.
