Mitigating Risk with a Business Impact Analysis |
CHAPTER |
AN IMPORTANT PART of a business continuity plan (BCP) is a business impact analysis (BIA). The BIA is largely a data collection process, and several methods are available for gathering that data, which include interviews, surveys, and meetings.
After the data has been collected, it can be analyzed to identify the critical functions and resources, after which acceptable outage times can be determined. The maximum acceptable outage (MAO) for a resource drives the recovery objectives, the two primary ones being recovery time objectives (RTOs) and recovery point objectives (RPOs).
