The certifiable international standard for business continuity management systems (BCMS) turns emergency binders into lived resilience – with a business impact analysis (BIA), clear recovery objectives and a binding exercise programme.
ISO 22301:2019 “Security and resilience – Business continuity management systems – Requirements” defines the requirements for a business continuity management system (BCMS): context, leadership, planning, support, operation, performance evaluation and improvement. Because the standard follows the Harmonized Structure (Annex SL), it integrates seamlessly with an existing ISO 27001 management system – and it is the certifiable standard for business continuity management.
Its core is Clause 8 (Operation): the business impact analysis (BIA) and risk assessment determine which processes must resume and how fast; from these follow business continuity strategies, solutions, plans and procedures that an exercise and test programme regularly puts to the test. Amendment 1:2024 adds climate change to the context analysis. The standard is flanked by ISO 22313 (implementation guidance), ISO/TS 22317 (BIA), ISO/TS 22318 (supply chain continuity) and ISO 22361 (crisis management).
Six elements decide whether your BCMS holds up when disruption strikes.
Which processes are critical, which resources do they need, and at what point does a disruption threaten the business? The BIA – methodically deepened in ISO/TS 22317 – delivers prioritised time objectives and underpins every subsequent decision.
The standard requires disruption risks to the prioritised processes to be systematically identified, analysed and evaluated – from IT outages and loss of premises to supply chain and workforce risks.
From the BIA and the risk picture emerge business continuity strategies and concrete solutions: redundant systems, alternate workplaces, alternative suppliers, recovery sequences – sized against the Recovery Time Objective (RTO) and the Recovery Point Objective (RPO).
Business continuity plans, recovery plans and a response structure define who does what, when and with which authority in an emergency – including warning and communication procedures for internal and external audiences.
ISO 22301 demands programmatic exercising and testing: from tabletop exercises to technical recovery tests. Only exercised plans are reliable plans – and every exercise yields documented improvements and audit evidence.
Top management owns the BCMS: business continuity policy, roles, resources, measurable objectives and management review. Thanks to the Annex SL structure, ISO 22301 shares this machinery with ISO 27001 – an integrated management system avoids duplicate work.
A certified BCMS is the strongest single piece of evidence for the continuity obligations under NIS2, DORA, ISO 27001 and Germany's KRITIS regime.
The NIS2 Directive explicitly requires business continuity – including backup management, disaster recovery and crisis management. ISO 22301 delivers exactly these capabilities as one coherent, certifiable system: from plan to documented exercise evidence.
The EU regulation on digital operational resilience in the financial sector requires, among other things, an ICT business continuity policy, response and recovery plans, and regular testing. A BCMS built on ISO 22301 structures these obligations and interlocks them with ICT risk management.
Annex A controls A.5.29 (information security during disruption) and A.5.30 (ICT readiness for business continuity) presuppose BCM capabilities without specifying the how. ISO 22301 fills precisely this gap – within the same Annex SL framework as your ISMS.
Operators of critical infrastructure must safeguard the availability of their critical services and demonstrate this to the German BSI. A BCMS based on ISO 22301 is a recognised state-of-the-art approach for preparedness, recovery and crisis organisation.
Four steps from the first analysis to a certification-ready BCMS.
We define the scope and the business continuity policy, identify the critical processes together with your business units, and derive prioritised recovery objectives (RTO/RPO) in the BIA – aligned with your IT.
We develop fitting continuity strategies and document business continuity plans, recovery plans and the crisis organisation – pragmatic, role-based and genuinely usable under pressure.
We build your exercise and test programme: tabletop exercises, communication tests, technical recovery tests. The results feed documented improvements – and produce the audit evidence at the same time.
We guide you through the internal audit, the management review and the certification audit (stage 1 and 2) – and then anchor the BCMS in day-to-day operation: KPIs, reviews and annual exercise cycles.
Four short questions show you in two minutes where your business continuity management stands today.
1Do you have a current business impact analysis (BIA) covering your critical processes and their dependencies?
2Are RTO and RPO defined per critical process and agreed with IT?
3Have your business continuity and emergency plans been exercised or tested within the last year?
4Is a crisis organisation in place with named roles, deputies and communication channels?
This self-check is a first orientation and does not replace a formal BIA or gap analysis.

Answers on ISO 22301 in practice.
Yes. ISO 22301 is the certifiable management system standard for business continuity. Certification works just like ISO 27001: a stage 1 audit (documentation review), a stage 2 audit (effectiveness review), then annual surveillance audits and re-certification after three years.
The business impact analysis (BIA) asks about the consequences of a disruption – regardless of its cause – and delivers priorities and time objectives (RTO/RPO). The risk assessment asks about possible causes and their likelihood. ISO 22301 requires both, because only together do they yield robust continuity strategies.
ISO 27001 requires continuity capabilities in controls A.5.29 and A.5.30, but does not specify the how. ISO 22301 delivers the complete BCMS including BIA, strategies and exercise programme – and also covers non-IT scenarios such as loss of premises or staff. Thanks to the identical Annex SL structure, both systems can be operated and audited in an integrated way.
A certified BCMS is the strongest single piece of evidence for the continuity obligations under NIS2 Art. 21(2)(c) and for DORA's requirements on ICT business continuity and testing. Both legal acts demand further measures beyond that, such as incident reporting processes – ISO 22301 covers the continuity core, and the evidence accrues naturally as the system operates.
The ISO-wide “Climate action changes” amendment of February 2024 extends Clause 4: organisations must determine whether climate change is relevant to their BCMS and consider climate-related requirements of interested parties. In practice this means extreme weather, supply chain and site scenarios belong in the context analysis and the BIA.
We build your BCMS to ISO 22301 – integrated with ISO 27001, aligned with NIS2, DORA and KRITIS, through certification and beyond.
