The best tool to enable risk-based decision making in support of a business continuity plan (BCP) is an impact analysis. An impact analysis is a process of identifying and evaluating the potential effects of an interruption or disruption of business operations on the organization's critical functions, processes, and resources. An impact analysis can help to determine the recovery priorities, objectives, and strategies for the BCP. Control analysis, root cause analysis, and threat analysis are other possible tools, but they are not as effective as an impact analysis.
