When the supervisor-to-subordinate ratio exceeds manageable span of control, what NIMS Management characteristic is described?

The correct answer is that a modular organization is described when the supervisor-to-subordinate ratio exceeds the manageable span of control. A modular organization allows for the dynamic scaling of the response structure based on the incident's size and complexity. This means that as the number of subordinates under a supervisor increases, the organization can create additional modules or teams to maintain effective oversight and control.

This characteristic helps ensure that supervisors maintain an effective span of control, typically ranging from three to seven subordinates, to ensure clear communication and management. When the number of direct reports exceeds this range, reorganizing into modules allows for better management practices, prevents overwhelming supervisors, and enhances response efficiency.

Options that refer to standard operating procedures, unity of command, or the incident command system capture different aspects of incident management but do not specifically address the structural organization necessary for maintaining effective control and coordination when faced with an excessive number of subordinates.
