What it asks for. The organisation must develop a contingency plan that identifies essential functions, recovery objectives, priorities and metrics, assigns roles and contact information, addresses maintaining essential functions during disruption and full restoration, is reviewed and approved, distributed, coordinated, updated and protected.
In practice. Good practice links the plan to a business impact analysis, defines recovery time and recovery point objectives for critical services and documents dependencies on suppliers and infrastructure. Plans should be tested and updated after tests and real events. Auditors expect the plan, impact analysis, test reports and review history. ISO 22301 and the DORA resilience requirements address the same area.
Common gaps. Plans are often IT-only and ignore business processes, people and suppliers. Recovery objectives are frequently set without checking that the technology can achieve them.
