What is ISO 22301?

The full name of this standard is ISO 22301:2019 Security and resilience – Business continuity management systems – Requirements. It is an international standard published by the International Organization for Standardization (ISO), and it describes how to manage business continuity in an organization. This standard is written by leading business continuity experts and provides the best framework for managing business continuity in an organization.

One of the features that differentiates this standard from other business continuity frameworks/standards is that an organization can become certified by an accredited certification body, and will therefore be able to prove its compliance to its customers, partners, owners, and other stakeholders.

ISO 22301 defines business continuity management as a part of overall risk management in a company, partially overlapping with information security management and IT management. Implementation and certification are useful to prove your company’s compliance to your partners, owners, and other stakeholders. ISO 22301 also helps you get new customers, by making it easier to demonstrate that you are among the best in the industry.

Relationship with ISO 22301:2012

The latest revision of ISO 22301 was published in October 2019. ISO 22301:2019 has replaced ISO 22301:2012, which was developed based on the British standard BS 25999-2. This 2019 revision does not bring big changes, but it definitely brings more flexibility and less prescriptiveness, adding more value to organizations and their customers.

What are the benefits of ISO 22301 – the business continuity standard?

There are four essential business benefits that a company can achieve with the implementation of this business continuity standard:

Comply with legal requirements. There are more and more countries defining laws and regulations requiring business continuity compliance. And beyond government interests, private businesses (e.g., financial institutions) are also requiring their suppliers and partners to implement business continuity solutions. And the good news is that ISO 22301 provides a perfect framework and methodology to support compliance with these requirements – by reducing administrative and operational effort, as well as the number of penalties to be paid. Read the article Laws and regulations on information security and business continuity to see a list of business continuity legislation worldwide.

Achieve marketing advantage. If your company is ISO 22301 certified and your competitors aren’t, you will have an advantage over them when it comes to customers who are sensitive about keeping the continuity of their operations, and the delivery of their products and services. Additionally, such certification can enhance your reputation and help you get new customers, by making it easier to demonstrate that you are among the best in the industry, leading to increased market share and higher profits.

Reduce dependence on individuals. More often than not, a company’s critical activities rely on just a few people who are hard to replace – a situation painfully demonstrated when these people leave the organization. Executives who are aware of this can make use of business continuity practices to become far less dependent on those individuals (either because of implemented replacement solutions or by documenting related tasks), meaning you can prevent a lot of headache when someone leaves the organization.

Prevent large-scale damage. In a world of real-time services and transactions, every minute of down service costs money – a lot of money. And, even if your business is not so sensitive to small periods of unavailability, disruptive incidents will cost you. By implementing business continuity practices compliant with ISO 22301, you will have a sort of insurance policy. Whether by preventing disruptive incidents from happening, or by becoming capable of faster recovery – your company will save money. And, the best thing of all is that your investment in ISO 22301 is far smaller than the cost savings you’ll achieve.

Who can implement this standard?

Any kind of organization – large or small, for profit or non-profit, private or public – can benefit from ISO 22301. The standard was conceived in such a way that it is applicable to any size or type of organization.

ISO 22301 implementation and certification can be considered essential to any company legally required to engage in contingency planning, including energy, transport, health, and essential public services.

How does ISO 22301 work?

The focus of ISO 22301 is to ensure continuity of business delivery of products and services after occurrence of disruptive events (e.g., natural disasters, man-made disasters, etc.). This is done by finding out business continuity priorities (through business impact analysis), what potential disruptive events can affect business operations (through risk assessment), defining what needs to be done to prevent such events from happening, and then defining how to recover minimal and normal operations in the shortest time possible (i.e., risk mitigation or risk treatment). Therefore, the main philosophy of ISO 22301 is based on analyzing impacts and managing risks: find out which activities are more important and which risks can affect them, and then systematically treat those risks.

The strategies and solutions that are to be implemented are usually in the form of policies, procedures, and technical/physical implementation (e.g., facilities, software, and equipment). In most cases, organizations do not have all the facilities, hardware, and software in place – therefore, ISO 22301 implementation will involve not only setting organizational rules (i.e., writing documents) that are needed in order to prevent disruptive incidents, but also developing plans and allocating technical and other resources to make the continuity and recovery of business activities possible. Because such implementation will require a number of policies, procedures, people, assets, etc. to be managed, ISO 22301 has described how to fit all these elements together in the Business Continuity Management System (BCMS).

How does business continuity fit into overall management?

Business continuity is part of overall risk management in a company, with areas that overlap with information security management and IT management.

Note: Risk management is part of overall corporate management.

Basic terms used in the standard

  • Business Continuity Management System (BCMS) – part of an overall management system that makes sure business continuity is planned, implemented, maintained, and continually improved
  • Maximum Acceptable Outage (MAO) – the maximum amount of time an activity can be disrupted without incurring unacceptable damage (also Maximum Tolerable Period of Disruption – MTPD)
  • Recovery Time Objective (RTO) – the pre-determined time at which a product, service, or activity must be resumed, or resources must be recovered
  • Recovery Point Objective (RPO) – maximum data loss, i.e., minimum amount of data used by an activity that needs to be restored
  • Minimum Business Continuity Objective (MBCO) – the minimum level of services or products an organization needs to produce to achieve its defined objectives after resuming its business operations

Content of ISO 22301

ISO 22301 is split into 11 sections, or clauses. Clauses 0 to 3 are introductory (and are not mandatory for implementation), while seven clauses (from 4 to 10) are the key clauses and are mandatory – meaning that all their requirements must be implemented in an organization if it wants to be compliant with the standard.

According to Annex SL of the International Organization for Standardization ISO/IEC Directives, the section titles in ISO 22301 are the same as those in ISO 27001:2013, ISO 9001:2015, and other management standards, enabling easier integration of these standards.

ISO 22301 requirements

Let’s take a look at the requirements of ISO 22301, which are given in clauses 4 to 10.

Clause 4 - Context: Organizations must understand who they are, what they are doing, and which processes and outputs they must sustain. They must also determine who has a stake in the continuity of operations – interested parties – and what their expectations are. Also, legal and regulatory requirements must be identified and documented. With this information, the organization establishes and documents its ISO 22301 scope. When determining the scope, the organization’s locations, missions, goals, products, and services must be considered.

Clause 5 - Leadership: For successful implementation of ISO 22301, organizations need the continuous support and leadership of top management. To show their commitment, the top management of the organization should develop, document, and communicate a policy within the organization and with interested parties while making resources available, directing and leading employees to contribute to the effectiveness of ISO 22301. For this purpose, organizational roles must be clearly defined with responsibilities, authorities, and competencies for each role.

Clause 6 - Planning: To plan for business continuity, organizations must understand what disruptions could potentially occur and how these incidents affect the business. Organizations must consider the consequences of risks, their impact, and the benefits of opportunities regarding their context and plan actions to address them. The standard also mandates organizations to set measurable BCMS objectives to guarantee the minimum viable products or services, as well as compliance with any legal or regulatory requirements. These objectives must be documented and communicated. To achieve them, organizations must have action plans within a timeframe, with responsibilities assigned.

Clause 7 - Support: No organization can advance without resources and support. Organizations must consider resource needs and provide them to meet their BCMS objectives. These resources may include infrastructure, technology, communication, competence, awareness, and documented information. The standard requires documented evidence of competence for the defined roles, such as training records, education, and professional background.

Clause 8 - Operation: This section of the standard describes the activities that should be performed to meet BCMS objectives and return to the normal way the organization operates. Key activities include:

  • Conducting and documenting a business impact analysis (BIA) and risk assessment. The BIA should identify the operational, legal, and financial impacts resulting from the disruption. While conducting the BIA, the duration of the disruption is an important input for determining impacts and, later, the recovery time. The risk assessment enables the organization to analyze the likelihood of disruption to its activities, and resources. Learn more about the BIA in the article How to implement business impact analysis (BIA) according to ISO 22301.
  • Developing a business continuity strategy Companies are required to develop a continuity strategy using the information gathered from the risk assessment and business impact analysis. Business continuity strategy essentially means the development of options and the selection of the most appropriate actions, including mitigation, response, and recovery. You can learn more about the importance of recovery in the article Can business continuity strategy save your money?.
  • Establishing and implementing business continuity procedures. Organizations are required to document business continuity plans and procedures based on the outputs of their strategy. The plans and procedures should have clear and specific steps for handling disruptions, well-defined roles and resource needs, and organized communication. For more information about developing plans and procedures, read the article Business continuity plan: How to structure it according to ISO 22301.
  • Exercising and testing the business continuity procedures. ISO 22301 requires periodic testing of plans and procedures to see if they are appropriate and effective. Test results must be reviewed and reported for recommendations and improvements. The article How to perform business continuity exercising and testing according to ISO 22301 explains more about the purpose and ways of exercising and testing, as well as how to prepare and whom to include.

Clause 9 - Performance evaluation: Organizations need to consider performance indicators and metrics; monitor, measure, analyze, and evaluate them; and then document the results. Planned internal audits should be conducted to measure the level of conformance to the standard and the organization’s own requirements. The audit program and results must be documented. Lastly, top management should review the effectiveness of the BCMS at planned intervals and document the results of these reviews.

Clause 10 - Improvement: Organizations shall have a methodology to address non-conformities, with root causes and corrective actions, as well as strategies for improvement on a continual basis. The standard mandates documented information for the evaluation of corrective actions. The organization needs to consider the results of the analysis and evaluation, and the outputs from the management review, to determine if there are needs or opportunities.

ISO 22301 certification

An ISO 22301 certificate is proof that a company has met the requirements of the standard, as well as the company’s commitment to business continuity. But is it mandatory? Like all ISO standards, ISO 22301 certification is a voluntary action and remains the choice of the organization. However, in many countries, for some business sectors, there are regulations for ISO 22301 certification. Examples can be found in industries like energy, finance, public transportation, and logistics. In addition, as mentioned before, companies have many benefits of implementing and getting certified by a third party after an assessment.

Every organization – large or small – that implemented ISO 22301 can apply to a certification body for assessment. But how can an organization get ISO 22301 certified? First, you must select a certification body. Selecting an accredited certification body is important, because accreditation bodies have rules for independent certification bodies, and it is internationally recognized. Certification bodies will ask you to send information about your organization, such as the number of employees and your core processes, so that they can submit an offer based on audit duration in man-days. Once you accept an offer and sign a contract with a certification body, your audit program starts.

Gap analysis and the two certification audit stages

Before the official audit program, there is an optional pre-audit called gap analysis where the certification body takes a closer look at the existing Business Continuity Management System and compares it to the ISO 22301 requirements. It saves time and money by identifying those areas that require more effort before starting the formal assessment.

The certification audit is carried out in two stages. During the first stage, the audit team checks if you meet the requirements of ISO 22301, such as mandatory documents and records, and looks over your implementation in general. It reviews your current business continuity management in the context of an ISO 22301 checklist. If the audit team finds differences, it will allow you to close them. If you meet all the requirements, the auditors will complete the official certification readiness audit.

Once you pass the certification audit, you will receive an ISO 22301 certificate valid for three years. For the next two years, you will have surveillance audits. Surveillances take less time, generally half the duration of the certification audit. And at the end of the third year, you must have a re-certification audit before your certification validity ends. Keep in mind that before every audit, whether it is certification, surveillance, or re-certification, the lead auditor sends you an audit plan that includes which elements of the standard will be audited, and when. At the end of every audit, an audit report is submitted. It must at least include a statement of conformity for the audited areas. If there are findings that resulted in nonconformity, you must take corrective actions to maintain your certificate.

How long does it take to get ISO 22301 certification?

Depending on the scale and complexity of the organization and business, the duration of effective implementation varies. It also depends on the resources and effort of the organization. Generally speaking, for small or medium-sized companies with fewer compliance requirements, it may take from three to six months. For large organizations with many sites, or companies that have to comply with many regulations, this duration can be a year or even longer (in cases like multinational energy companies or public sector health institutions). But whatever the type of company is, having a good and clear project plan for establishing ISO 22301 is essential. Within this timescale, you’ll also need to count on the certification audit period before having your certificate issued by a certification body.
