What Does a Business Impact Analysis Best Enable an Organization to Establish?
Short answer
C A business impact analysis identifies critical functions and dependencies to establish restoration priorities for operational continuity.
Question
Key Takeaways
Tests understanding of BIA scope versus risk assessment and disaster recovery planning, with the common trap being confusion between impact analysis and calculating financial losses like ALE.
A Business Impact Analysis (BIA) primarily identifies critical functions and their operational dependencies to establish restoration priorities. Community consensus confirms this as the definitive purpose of a BIA in CISM exams.
Common mistake: Option A (ALE) is frequently chosen by candidates confusing BIA with quantitative risk assessment, but ALE belongs to risk calculation, not business impact prioritization.
Expert Analysis
Why the Answer Is Correct
The Business Impact Analysis (BIA) is a foundational step in business continuity planning that evaluates the potential effects of an interruption to critical business operations. By quantifying operational, financial, and reputational impacts, it directly informs which systems and processes must be restored first, thereby establishing clear restoration priorities. This aligns with ISACA's framework for prioritizing resources based on business necessity rather than technical complexity.
Why the Other Options Are Wrong
Annualized Loss Expectancy (ALE) is derived from quantitative risk assessments using Single Loss Expectancy and Annual Rate of Occurrence, not from a BIA. Recovery methods are designed during the subsequent disaster recovery or business continuity plan development phase, after priorities are already defined. Total Cost of Ownership (TCO) is a financial evaluation metric for IT acquisitions and has no direct relationship to disruption impact analysis.
Community Comment Notes
Multiple verified contributors confirm that identifying critical functions and their dependencies naturally leads to prioritizing restoration efforts. One highly rated comment explicitly states that a BIA assesses disruption impacts to effectively prioritize restoration, reinforcing the direct link between impact analysis and resource allocation sequencing.

Exam Strategy
When encountering BIA questions on the CISM exam, immediately associate it with business process criticality and resource prioritization rather than technical recovery steps or financial risk calculations. Focus on the "business" aspect of the analysis to eliminate technical or purely financial distractors.
