The ongoing process of evaluating a developing incident to determine the best course of action is called:

• A. Decision-making
• B. Size-up
• C. Planning
• D. Response

Answer: (B)

Size-up is the ongoing process of evaluating conditions at a developing incident to decide the best course of action. On arrival and as conditions evolve, you continuously gather information about fire behavior, building construction, hazards, occupant location, and available resources. This evolving understanding drives priorities (life safety, incident stabilization, property conservation) and shapes tactics. Planning comes after this assessment, forming the incident action plan, while decision-making is the act of choosing among options within that ongoing evaluation. The actual actions taken to implement the plan are the response.
