What is a Business Impact Analysis (BIA)?

A Business Impact Analysis (BIA) is a foundational process within business continuity management. It systematically identifies an organization's critical business functions and resources and then evaluates the potential quantitative (financial) and qualitative (reputational, operational) impacts that would result from their disruption. The primary purpose of the BIA is to gather data that helps determine recovery priorities and objectives, such as the Recovery Time Objective (RTO) and Recovery Point Objective (RPO). This analysis provides the essential justification for subsequent business continuity and disaster recovery planning efforts.

A. A BIA is a comprehensive analytical process, not merely a document, and it assesses interruptions from any cause, not just security events.

B. A BIA is a strategic planning tool used to prepare for disruptions, not a tactical checklist for use during an intervention.

D. This describes a Business Continuity Plan (BCP) or Disaster Recovery Plan (DRP), which are created using the findings of a BIA, not the BIA itself.
