The best way to enable the mapping of cost to risk for selecting a disaster recovery site based on available risk data is to perform a business impact analysis (BIA). A BIA is a process of identifying and evaluating the potential effects of various disaster scenarios on the critical business functions and processes of an organization. A BIA can help estimate the financial and operational impacts of losing or disrupting the business functions and processes, such as revenue loss, customer dissatisfaction, regulatory fines, contractual penalties, reputation damage, etc. A BIA can also help determine the recovery time objectives (RTOs) and recovery point objectives (RPOs) for each business function and process, which indicate how quickly and how much data they need to be restored after a disaster. By performing a BIA, the IT steering committee can map the cost of each disaster recovery site option to the risk of each disaster scenario, and compare the trade-offs between different levels of protection and investment1.
The other options are not the best ways to enable the mapping of cost to risk for selecting a disaster recovery site. Key risk indicators (KRIs) are metrics that indicate the level of risk exposure or potential impact of a risk event on an organization. KRIs can help monitor and manage IT risks, but they do not necessarily reflect the cost of different disaster recovery site options. Scenario-based assessment is a method of analyzing and evaluating the likelihood and consequences of various risk scenarios. Scenario-based assessment can help identify and prioritize IT risks, but it does not provide a clear measure of the cost of different disaster recovery site options. Qualitative forecasting is a technique of using expert opinions, judgments, or intuition to predict future outcomes or trends. Qualitative forecasting can help estimate the future demand or growth of IT services, but it does not provide a reliable or objective basis for mapping the cost to risk of different disaster recovery site options.
