What term describes an emergency management model of authority?

In the traditional hierarchy of emergency management and the Incident Command System (ICS), the model of authority is described asVertical. This refers to a "Top-Down" command structure where decisions flow from the Incident Commander (at the top) down to the operational personnel. This verticality ensures a clearChain of Command, which is essential for maintaining order, accountability, and safety during the high-stress environment of a disaster response.

The vertical model is designed to prevent "management by committee," which can be slow and indecisive. In a life-safety situation, a single individual (the Incident Commander) must have the ultimate authority to make rapid decisions. This structure is reinforced by the principle ofUnity of Command, which dictates that every individual in the organization reports to exactly one supervisor. This vertical reporting relationship ensures that instructions are not conflicting and that every responder knows exactly where they fit within the organizational chart.

While modern emergency management often involves "Coordinated" (Option A) efforts between multiple agencies (throughUnified Command), the authoritywithineach agency or within the integrated ICS structure remains strictly vertical. Even in a Unified Command scenario, where leaders from different jurisdictions work together to develop a single set of objectives, those objectives are carried out through a vertical chain of subordinates. An "Inclusive" (Option B) model is often used in theplanningormitigationphases to gather diverse stakeholder input, but it is not the "model of authority" used during active incident operations. For aCEDPprofessional, understanding the vertical nature of authority is critical for ensuring that the organization can scale up or down (modularly) while maintaining a strict and reliable flow of information and orders from the command level to the tactical field units.
