A business continuity plan (BCP) is the best option that enables an organization to operate smoothly with reduced capacities when service has been disrupted, as it defines the processes and procedures to maintain or resume critical business functions and minimize the impact of the disruption on the organization's objectives, customers, and stakeholders. A BCP also includes strategies for resource management, communication, recovery, and testing.
