What structure is recommended to assign ownership and ensure synchronization of time-bound actions during a large disturbance?

• A. A decentralized approach with no central ownership
• B. An ICS-like structure with clear ownership and a single time reference
• C. A loose team-based approach with ad hoc timing
• D. A quarterly steering committee review

Answer: (B)

During a large disturbance, coordinating actions with a single, authoritative structure is essential. An ICS-like setup provides a clear command chain and defined roles, so everyone knows who makes decisions, who executes them, and how work items are tracked. This central ownership keeps actions aligned with a shared plan, which is crucial as the situation evolves and priorities shift in real time.

Coupled with this, having a single time reference ensures every action, event, and log uses the same clock. When multiple teams and devices are operating simultaneously, a unified time basis prevents timing mismatches that can lead to unsafe switching, misordered steps, or conflicting actions. The incident action plan within an ICS framework guides responders through coordinated tasks, time-bound targets, and scalable coordination as the disturbance grows.

In contrast, a decentralized setup without a central owner can create confusion about authority, an ad hoc timing approach invites mis-timed actions, and waiting for a quarterly steering committee is far too slow for real-time response. The ICS-like structure with clear ownership and a single time reference best supports synchronized, effective action during a large disturbance.
