What is a business impact analysis (BIA) and why is it important?

• A. Identifies critical functions, assesses disruption impacts, informs continuity strategies and prioritization.
• B. Determines device procurement cycles.
• C. Measures quarterly revenue growth.
• D. Sets the annual IT budget.

Answer: (A)

A business impact analysis identifies essential business functions, evaluates the consequences of disruptions to those functions, and uses that information to shape continuity strategies and determine prioritization. This matters because it reveals which processes must be protected, how long they can be down before operations are seriously harmed, and what resources and controls are needed to recover quickly. It also helps set realistic recovery time objectives and recovery point objectives, maps dependencies across people, processes, and systems, and justifies resilience investments. The other options miss the scope by focusing on device purchases, revenue metrics, or budgeting, none of which address identifying critical functions and the impact of interruptions to guide recovery planning.
