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

The correct answer highlights the concept of a modular organization within the National Incident Management System (NIMS). When the supervisor-to-subordinate ratio exceeds a manageable span of control, it signifies that the structure is becoming too complex for effective supervision. A modular organization allows for the breakdown of teams into manageable units, ensuring that each supervisor can effectively oversee their subordinates without being overwhelmed.

This management characteristic emphasizes creating smaller, more focused teams that can enhance the clarity of roles and responsibilities, thereby improving overall efficiency. When implemented correctly, modular organization helps maintain an effective span of control by providing a clear hierarchy and enabling better communication and coordination among various units.

The other options focus on different aspects of incident management. An incident action plan pertains to the strategic outline for incident management, integrated communication emphasizes the sharing of information across all levels, and management by objectives refers to the clear setting of goals and performance objectives. Each of these has its place within NIMS, but they do not specifically address the scenario of an unmanageable supervisor-to-subordinate ratio as effectively as the concept of modular organization does.
