Business continuity requirements vary by jurisdiction, sector, legal entity and service. A multinational organization should not treat a single standards list as legal advice or assume that certification to ISO 22301 automatically satisfies every local resilience obligation. The practical task is to maintain a traceable requirements register.
Use a hierarchy of requirements
| Layer | Examples | What to record |
|---|---|---|
| Law/regulation | Sector resilience, safety, financial or critical-infrastructure rules | Authority, citation, applicability, deadline |
| National guidance | Government or national standards-body guidance | Status: mandatory, expected or voluntary |
| International standard | ISO 22301 and supporting guidance | Adopted scope and control mapping |
| Contract | Customer continuity, recovery and notification clauses | Service, SLA, evidence and remedies |
| Internal policy | Group BCM standard | Owner, exceptions and assurance method |
Do not confuse standards with regulation
ISO 22301 is an international management-system standard. A regulator may reference it, require comparable controls, or impose different recovery, testing, incident-notification or outsourcing expectations. Record the source and legal status of every obligation instead of labelling everything “ISO compliance.”
Country assessment method
- List legal entities, operating countries and regulated services.
- Identify competent regulators and national standards bodies.
- Search official sources for continuity, operational resilience, disaster recovery, outsourcing, cyber resilience and emergency-management obligations.
- Ask legal/compliance owners to confirm applicability.
- Map each requirement to BCM processes and evidence.
- Record conflicts and apply the stricter requirement where governance determines this is appropriate.
- Review at least annually and when entering a new market or changing a regulated service.
Example requirements register
A financial service operating in three countries may have one group BCMS but different incident-notification windows, outsourcing expectations and testing frequencies. The register should therefore map a common control such as “exercise critical services” to each local requirement, identify the strictest applicable frequency, and retain evidence showing which legal entity and service were tested.
Evidence that auditors can follow
For every obligation, keep the authoritative source, interpretation owner, mapped control, implementation evidence, assurance result and exception status. Screenshots of web pages are weak evidence if the underlying rule changes; retain a controlled citation or official publication reference and the date it was reviewed.
Common mistakes
- Copying an internet list without checking official sources.
- Assuming certification eliminates sector-specific obligations.
- Ignoring contractual continuity clauses.
- Applying headquarters requirements to all legal entities without applicability review.
- Failing to track changes in regulation.
- Using “best practice” as if it were mandatory law.
Decision checklist
- Countries and regulated services are inventoried.
- Each requirement has an authoritative source.
- Mandatory and voluntary requirements are distinguished.
- Legal/compliance has confirmed applicability.
- Controls and evidence are mapped.
- Exceptions have accountable approval.
- A regulatory-change trigger exists.
Is ISO 22301 mandatory everywhere?
No. Its applicability depends on organizational choice, contracts, regulators and jurisdiction. Some organizations use it as a management-system framework without seeking certification.
Which requirement wins when rules differ?
That is a governance and legal decision. Organizations commonly design a group baseline and add local requirements, but conflicts should be assessed by qualified legal or compliance owners.
How often should the register be reviewed?
At least on a defined periodic cycle and whenever regulation, legal entities, critical services, outsourcing arrangements or operating countries change.
Build country profiles without creating parallel programmes
For each jurisdiction, maintain a concise profile covering legal entity, regulated activities, sector obligations, contractual commitments, recognized standards and the responsible compliance owner. Link each requirement to the enterprise BCM control that satisfies it. This allows one operating process to support several obligations while still showing country-specific applicability.
Where a local requirement is more prescriptive than the global standard, record the additional control explicitly. Where the global programme is stronger, retain the common control and show how it meets the local expectation. Avoid separate country binders that drift away from operational practice.
Validate sources and dates
Regulations, supervisory guidance and standards change. Record the issuing authority, publication or effective date, official source and date last reviewed. Do not rely on vendor summaries as the authoritative basis for a compliance decision. If interpretation is uncertain, flag it for legal or regulatory review rather than presenting an assumption as a requirement.
Scenario for a multinational service
A shared payments platform supports entities in three countries. One jurisdiction has a specific outage-reporting expectation, another requires stronger third-party oversight, and the third relies mainly on contractual commitments. The continuity design can remain common—shared recovery architecture, tested failover and supplier controls—while the notification, evidence-retention and governance steps vary by entity. The requirements register should make those differences visible to responders.
Change-management trigger
Review the register when entering a new market, launching a regulated service, changing a critical supplier, restructuring a legal entity or receiving new supervisory guidance. Treat the register as an input to solution design and exercises, not an annual compliance spreadsheet.
Document interpretation ownership
Where a requirement is ambiguous, record who interpreted it and whether legal, compliance or regulatory specialists were consulted. Keep the interpretation beside the control mapping so future reviewers understand why the organization chose a particular implementation. Revisit the interpretation when official guidance or the operating model changes.
Build a requirements register before comparing frameworks
Organizations operating across jurisdictions should distinguish international standards, national guidance, sector regulation, contractual obligations and internal policy. These sources do not have the same authority. A requirements register should record the jurisdiction, sector, issuing body, legal or contractual status, applicability, effective date, responsible owner, evidence location and review date. This prevents a generic “country standard” list from being treated as legal advice or as a substitute for checking the original source.
Where a global BCMS is used, map local requirements to common controls only after identifying genuine differences. A global exercise framework may satisfy most locations, for example, while one jurisdiction or regulated sector requires specific notification, record retention, testing or reporting evidence. Those differences should be explicit extensions to the common control set rather than hidden in local spreadsheets.
Review rules for a defensible register
- Link each requirement to the authoritative source and retain the date it was checked.
- Separate mandatory obligations from guidance, certification criteria and good practice.
- Assign a business or legal owner to interpret ambiguous applicability; BCM should not make legal determinations alone.
- Record superseded references so old requirements do not continue to drive controls after a change.
- Map each applicable requirement to evidence such as policy, BIA, plan, exercise, supplier control or reporting record.
The practical objective is traceability: a reviewer should be able to move from a country or sector requirement to the control that addresses it and then to current evidence. When requirements conflict or create materially different recovery expectations, escalate the decision rather than averaging the obligations into a generic global target.
