Thebusiness impact analysis (BIA)identifies critical services, acceptable downtime limits, and the business consequences of disruptions. CRISC emphasizes that the BIA is the foundation for deciding risk treatment strategies because it defines what must be restored first and to what level. Scenario analysis identifies risks but does not determine business priorities. Failover procedures are themselves a treatment, not a method for selecting treatments. A risk treatment plan documents chosen actions but depends entirely on the BIA to inform those decisions. Therefore, the BIA is the key input enabling proper treatment selection during disasters.
