Guidance, not requirements
ISO 22313 explains approaches and recommendations rather than adding a second set of certification requirements.
Adaptation
The guidance is intended for organizations of different types and sizes.
Alignment
Using ISO 22313 alongside ISO 22301 can help teams understand the intent behind management-system requirements.
Revision status
ISO lists a new work item for a future ISO 22313 revision, while the 2020 edition remains the published guidance.
Business continuity is organization-specific. Recovery priorities, legal duties, safety requirements, contracts, insurance terms and technical recovery methods should be validated by the responsible people in the organization.
