A business impact analysis (BIA) should be completed first before risk calculation and prioritization. A BIA is a process that identifies and evaluates the potential effects of disruptions to critical business functions or processes. A BIA helps to determine the recovery priorities, objectives, and strategies for the organization's assets and resources1. A BIA is a prerequisite for risk calculation and prioritization because it provides the basis for estimating the impact and likelihood of various threats and vulnerabilities on the organization's operations, reputation, and finances2.
