Business Impact Analysis

Business impact analysis (BIA) evaluates time-sensitive impacts from losing critical processes, systems, or resources, establishing maximum tolerable downtime and recovery objectives. BIA quantifies financial losses, regulatory penalties, customer impacts, and reputational damage over time. Results drive recovery time objectives (RTO), recovery point objectives (RPO), and resource requirements for continuity strategies. For example, a stock exchange BIA might determine that trading systems require 15-minute RTO with zero data loss, while HR systems tolerate 48-hour outages. BIA informs business continuity planning, disaster recovery investments, and third-party service level agreements. Effective BIAs involve business owners, consider dependencies and cascading impacts, and update regularly as operations evolve.
