When an incident expands, which statement is true regarding the functions and positions filled?

When an incident expands, it is important to focus on filling only the essential positions to effectively manage the situation. This approach allows for a streamlined response, ensuring that critical functions are maintained without overcomplicating the structure. In an expanding scenario, there may be no need to fill every single role immediately, especially if those roles are not essential to the current phase of the incident response.

The goal is to maintain flexibility and adapt to the evolving needs of the incident. By prioritizing essential positions, the incident command can allocate resources efficiently and ensure that the most important functions are covered first. This helps in making quick decisions, coordinating response efforts, and maintaining clarity in command structure.

The other options do not reflect the best practices of incident management. Immediate filling of all positions may lead to confusion and inefficiency, while focusing solely on supervisory roles ignores the critical support functions that may be necessary. Furthermore, keeping all previous personnel in their roles may not always align with the dynamic nature of expanding incidents, where reassignment may be needed based on capabilities or roles that are no longer relevant.
