Business impact analysis (BIA) is the most useful analysis for prioritizing risk scenarios associated with loss of IT assets, because it evaluates the potential consequences of disruption tocritical business functions and processes. BIA helps to identify the most significant risks and the most urgent recovery needs. SWOT analysis, cost-benefit analysis, and root cause analysis are all useful tools for different purposes, but they do not directly address the impact of risk scenarios on business continuity and resilience.
