What is a BCMS?
The BCMS (business continuity management system) is the organisational frame behind the BCP. It is not a single document but a permanently operated control system with clear responsibilities, policies and processes. Its job is to make sure contingency plans are not written once and then forgotten, but grow out of a business impact analysis, are tested regularly, are reviewed after exercises and incidents and are continuously improved. That is the step the system makes possible: Business continuity stops being a one-off measure and becomes a managed, demonstrable programme.
The cycle
Like an ISMS , a BCMS follows the plan-do-check-act principle of continuous improvement: plan, implement, test, refine. That keeps the ability to keep going current even as processes, the IT estate or the threat picture change. The management body carries overall responsibility and sets the objectives and the resources.
A typical case: a hospital runs its BCMS so that a different scenario is exercised each quarter – the failure of the clinical information system, for instance. After every exercise the findings feed into updated contingency plans, newly critical applications are taken into scope, and the management body receives a report. That keeps contingency planning alive instead of letting it go stale after the first audit.
BCMS and ISO 22301
The international standard ISO 22301 describes how a BCMS is built and run. Organisations can certify against it – much as they can against ISO 27001 for information security – and so create recognised evidence of their readiness towards customers and authorities.
BCMS and NIS2
Article 21(2)(c) of the NIS2 Directive, which has applied since 18 October 2024, requires measures for business continuity, backup management, disaster recovery and Crisis management. A BCMS is the fitting tool for meeting those requirements in a structured, repeatable and demonstrable way, rather than scattering them across loose individual measures.

Frequently asked questions
What is a BCMS?
A BCMS (business continuity management system) is the overarching management system for contingency planning, steering how the ability to keep going is planned, tested and continuously improved. It is not a single document but a permanently operated control system with clear responsibilities, policies and processes. The BCMS makes sure that contingency plans grow out of a business impact analysis, are tested regularly and are improved after exercises or incidents.
How do a BCMS and a BCP differ?
The BCMS is the overarching management system that organises responsibilities, testing and continuous improvement of contingency planning. The BCP, the business continuity plan, is by contrast a concrete, documented plan that is created and maintained inside that system. The BCMS is therefore the organisational frame, while the BCP supplies the operational instructions for the moment things go wrong.
Which standard sits behind a BCMS?
The reference is the international standard ISO 22301, which describes how a business continuity management system is built, run and certified. It follows the same plan-do-check-act principle as ISO 27001 for information security. Organisations can certify against ISO 22301 and so create recognised, externally audited evidence of their readiness towards customers, partners and authorities. NIS2 itself names no standard: Article 21(2)(c) requires business continuity, backup management, disaster recovery and crisis management, and leaves the route open.
