Business impact analysis (BIA) is a process that involves analyzing the potential consequences of an IT risk event on the organization’s critical business functions and processes. BIA can help to understand the severity and duration of the disruption, the financial and operational losses, the recovery time objectives, and the recovery point objectives. BIA can also help to prioritize the recovery activities and resources, as well as to determine the acceptable level of risk and the risk mitigation strategies. BIA is the most helpful tool to understand the consequences of an IT risk event, as it provides a comprehensive and quantitative assessment of the impact and the recovery requirements. References = Risk and Information Systems Control Study Manual, Chapter 4, Section 4.4.2, p. 206-207
