What are the initial steps in the command sequence according to the classical methodology of decision making?

The initial steps in the command sequence according to the classical methodology of decision-making begin with size-up, followed by strategy and tactics, and then implementing an action plan.

Size-up is crucial as it involves assessing the incident scene, gathering vital information about the environment, hazards, and potential victims, which forms the foundation for effective decision-making. After this assessment, establishing a clear strategy and tactics allows the Incident Commander to determine the overall approach to managing the incident. Finally, developing and implementing an action plan translates these strategies into specific tasks and assignments for responding personnel.

This structured sequence ensures that decisions are made based on comprehensive situational awareness, enhancing operational effectiveness in emergency response scenarios.
