Comprehensive and Detailed Explanation (aligned to ISACA CRISC guidance) CRISC and business continuity guidance stress that BCP development starts from understanding and prioritizing critical business services and processes derived from the business impact analysis (BIA).
Prioritization allows the organization to define recovery time objectives (RTOs), recovery point objectives (RPOs), and sequence of restoration, ensuring limited resources are first focused on the processes that protect life, safety, regulatory obligations, revenue, and reputational value. Identifying alternate locations and DR sites, and designing communication plans, are essential elements of continuity and disaster recovery planning, but they are built around the set of prioritized services. Without a clear hierarchy of what must be restored first and to what level, the BCP will be unfocused and may fail to meet business expectations during a disruption.
