Final answer:
An Incident Commander should conduct a thorough sizeup of the incident and establish clear objectives to identify resource requirements, leading to informed development of an Incident Action Plan.
Step-by-step explanation:
The first step in managing resources during an incident is indeed to identify requirements. To effectively achieve this, an Incident Commander should conduct a thorough assessment or "sizeup" of the current incident situation and future incident potential. This involves understanding the scope of the incident, the resources on hand, and the potential developments of the situation.
The Incident Commander must have clear stated objectives which inform the development of an Incident Action Plan (IAP) and ensure that resource management is aligned with these objectives. The Logistics Section is then tasked with developing a staffing plan based on the IAP, and this plan needs to be adaptable depending on the dynamics of the incident. Additionally, resource prioritization decisions are often made by the Incident Commander or Operations Section Chief rather than delegating them to the Finance and Administration Section Chief, as resource decisions are typically operational rather than financial.
