Two Things That Sound Similar But Are Not the Same
If you have ever sat in a risk meeting and heard someone use “business continuity” and “disaster recovery” interchangeably, you are not alone. Most people do it. But if you are thinking about ISO 22301 certification, or simply trying to build a resilient organisation, the distinction between ISO 22301 and a disaster recovery plan matters a great deal.
On this page
ISO 22301 is an international standard for a Business Continuity Management System, or BCMS. A disaster recovery plan, often called a DRP, is a specific document or set of procedures. One is a management framework. The other is a tactical response tool. They are related, but they operate at very different levels. Confusing them can lead to significant gaps in how your organisation actually responds when something goes wrong.
This article breaks down both concepts clearly, explains how they relate to each other, and helps you decide what your business actually needs.
What Is ISO 22301?
ISO 22301 is the internationally recognised standard for Business Continuity Management Systems. It was first published in 2012 and updated in 2019. The standard provides a framework for planning, establishing, implementing, operating, monitoring, reviewing, maintaining, and continually improving a BCMS.
In plain terms, it tells your organisation how to build and manage a system that keeps critical business functions running during and after a disruption. That disruption could be a cyberattack, a flood, a pandemic, a supplier failure, a power outage, or any number of other events.
ISO 31000, the risk management standard, and ISO 22301 are closely linked in practice. ISO 22301 requires you to identify risks to your operations, assess their potential impact, and build systematic responses. But it goes further than risk management alone. It demands that you actually test whether your organisation can survive and continue operating when those risks materialise.
What ISO 22301 Covers
The standard follows the same high-level structure as other ISO management systems standards, which means it covers leadership commitment, planning, support, operations, performance evaluation, and improvement. Specifically for business continuity, it requires:
- A business impact analysis, or BIA, to identify which functions are critical and how long the organisation can survive without them
- Risk assessment to understand what threats exist and how likely they are
- Business continuity strategies and solutions to address identified gaps
- Business continuity plans, including communication plans and recovery procedures
- Regular testing and exercising of those plans
- Management review and continual improvement
ISO 22301 is certifiable. An accredited certification body can audit your BCMS against the standard and issue a certificate if you meet the requirements. That certificate tells clients, regulators, and partners that your organisation has a verified, systematic approach to staying operational under pressure.
What Is a Disaster Recovery Plan?
A disaster recovery plan is a documented set of procedures that describes how your organisation will recover specific systems, assets, or functions after a disruptive event. It is typically focused on technology and IT infrastructure, though the term is also used more broadly in some industries.
A DRP answers questions like: what do we do when our primary data centre goes offline? How do we restore our core systems? Who calls whom? What is the recovery time objective for each system? Where do staff work if the office is inaccessible?
A disaster recovery plan is a document or a collection of documents. It is not a management system. It does not require leadership commitment structures, management reviews, or continual improvement cycles. It is a procedure. A very important procedure, but a procedure nonetheless.
What a Disaster Recovery Plan Typically Includes
- A list of critical systems and infrastructure
- Recovery time objectives, known as RTOs, and recovery point objectives, known as RPOs
- Step-by-step recovery procedures for each system or function
- Contact lists for internal staff and external vendors
- Backup and data restoration procedures
- Instructions for activating alternate sites or cloud environments
- Testing and review schedules
A well-written DRP is essential. But it is reactive by nature. It tells you what to do after something has already gone wrong. It does not tell you how to build an organisation-wide culture of resilience, how to identify which functions are truly critical, or how to ensure leadership is engaged in continuity planning at a strategic level.
The Core Difference: System vs Document
The most important distinction is this: ISO 22301 is a management system standard. A disaster recovery plan is a document. That might sound like a simple difference, but in practice it changes everything.
A management system under ISO 22301 is a living, governed structure. It has an owner at the leadership level. It is reviewed regularly. It is tested. It is updated when the business changes. It covers the entire organisation, not just the IT department. And it is subject to both internal audits and external audits by an independent certification body.
A disaster recovery plan, even a very good one, can sit in a shared drive and never be touched again after it is written. It might be accurate on day one and completely outdated within twelve months. Without a management system around it, there is no mechanism to ensure it stays relevant.
Think of it this way. ISO 22301 is the engine. A disaster recovery plan is one of the parts inside that engine. The DRP is a required output of a properly implemented BCMS. You cannot have a complete ISO 22301 system without recovery plans. But you can have a recovery plan without any of the governance, testing, or strategic oversight that ISO 22301 demands.
Business Continuity vs Disaster Recovery: Scope Matters
Another important distinction is scope. Business continuity, as defined within ISO 22301, covers the entire organisation. It asks: which of our products and services are critical? What processes deliver them? What resources do those processes depend on? What happens to our people, our premises, our suppliers, and our technology if there is a disruption?
Disaster recovery, in its traditional sense, tends to focus on technology recovery. It is narrower. It answers the IT question. Business continuity answers the whole-of-business question.
A hospital, for example, needs more than a plan to restore its electronic health records system. It needs to know how it will continue treating patients if its main building is unusable, if key staff are unavailable, if a critical medical supplier fails to deliver, and if communications infrastructure is down. ISO 22301 addresses all of that. A disaster recovery plan typically addresses the IT component only.
This is not to say a DRP is insufficient on its own for every organisation. A small software company with no physical premises, minimal staff, and cloud-based infrastructure might find that a solid DRP covers most of its continuity needs. But for organisations with complex operations, multiple sites, regulatory obligations, or significant dependencies, the broader framework of ISO 22301 is far more appropriate.
How ISO 22301 and a Disaster Recovery Plan Work Together
The good news is that these two things are not in competition. They are complementary. A well-implemented ISO 22301 BCMS will produce a disaster recovery plan as one of its outputs, alongside other plans such as a crisis communications plan, an incident response plan, and a business continuity plan for each critical function.
Within the ISO 22301 framework, the disaster recovery plan sits under the broader business continuity strategy. The BIA identifies which systems are critical and what the acceptable recovery timeframes are. Those findings inform the DRP. The DRP is then tested through exercises, and the results feed back into the management review process. Any gaps found during testing trigger corrective actions, which improve both the DRP and the broader BCMS.
This is the cycle that makes ISO 22301 so valuable. It does not just create plans. It creates a system that ensures those plans stay current, tested, and effective.
If you are already working on ISO 27001 for information security, you will find that ISO 22301 integrates naturally alongside it. Many organisations pursue both standards together, since a significant portion of business continuity risk in modern organisations is information security related.
Who Needs ISO 22301 Certification?
ISO 22301 certification is not mandatory in Australia or most other jurisdictions. But there are strong commercial and regulatory reasons why many organisations pursue it.
Government contracts increasingly require evidence of business continuity capability. Financial services regulators, healthcare accreditation bodies, and critical infrastructure operators often mandate or strongly prefer certified BCMS. Major enterprise clients in supply chains will sometimes require their key suppliers to hold ISO 22301 certification as a condition of doing business.
Beyond compliance, the process of implementing ISO 22301 forces an organisation to genuinely understand its own critical dependencies. Many businesses discover during their BIA that they have been significantly underestimating the impact of losing a key supplier, a single system, or even a single person. That discovery alone is often worth the investment.
Industries where ISO 22301 is most commonly pursued include:
- Financial services and banking
- Healthcare and aged care
- Telecommunications and utilities
- Government and defence
- Data centres and managed service providers
- Logistics and supply chain operations
Do You Need ISO 22301 or Just a Better Disaster Recovery Plan?
This is the practical question most business owners are actually asking. Here is an honest answer.
If your organisation is relatively small, operates primarily through IT systems, and has no regulatory requirement or client demand for certified business continuity, you may not need ISO 22301 certification right now. A well-structured, regularly tested disaster recovery plan may be sufficient for your current situation.
But if any of the following apply to you, ISO 22301 is worth serious consideration:
- You operate in a regulated industry where business continuity is a compliance requirement
- You supply goods or services to large enterprises or government agencies that ask for evidence of continuity capability
- Your organisation has complex operations across multiple sites, functions, or geographies
- You have experienced a disruption in the past and found that your recovery was slower or more chaotic than it should have been
- You want a competitive differentiator that demonstrates organisational resilience to clients and investors
It is also worth noting that implementing ISO 22301 does not require you to start from scratch. If you already have a disaster recovery plan, a crisis communications procedure, or any existing continuity documentation, those become inputs into your BCMS. The standard provides the governance structure around what you already have, fills the gaps, and ensures the whole thing is maintained properly over time.
Common Misconceptions Worth Clearing Up
Misconception 1: A Disaster Recovery Plan Is Enough for ISO 22301
It is not. A DRP covers one component of what ISO 22301 requires. The standard also requires leadership commitment, a business impact analysis, risk assessment, communication plans, training and awareness programs, internal audits, management reviews, and a continual improvement process. A DRP alone does not satisfy these requirements.
Misconception 2: ISO 22301 Is Only for Large Organisations
The standard is scalable. ISO 22301:2019 explicitly states that its requirements are generic and intended to be applicable to all organisations regardless of type, size, or nature. A small business with ten staff can implement a proportionate BCMS that meets the standard. The complexity of implementation scales with the complexity of the organisation.
Misconception 3: Once Certified, You Are Done
ISO 22301 certification requires ongoing surveillance audits, typically annually, and a full recertification audit every three years. More importantly, the standard requires continual improvement. Your BCMS must evolve as your business changes. A system that was accurate and tested two years ago may have significant gaps today if your operations have grown or changed.
Misconception 4: ISO 22301 and a DRP Cover the Same Risks
A disaster recovery plan is typically focused on technology and infrastructure recovery. ISO 22301 covers all critical business functions, including people, premises, suppliers, and processes. The scope of ISO 22301 is substantially broader than a traditional DRP.
Getting Started: Practical Steps
If you have decided that ISO 22301 is the right direction for your organisation, here is a realistic starting point.
- Conduct a gap analysis. Compare your current business continuity documentation and practices against the requirements of ISO 22301:2019. Identify what you have, what is missing, and what needs to be improved.
- Complete a business impact analysis. This is the foundation of your BCMS. Identify your critical products and services, the processes that deliver them, and the maximum tolerable period of disruption for each.
- Develop or update your recovery strategies. Based on the BIA findings, determine how you will maintain or restore critical functions within acceptable timeframes.
- Document your plans. This includes your business continuity plans, disaster recovery plan, crisis communications plan, and any other procedural documents required by the standard.
- Test and exercise. Run tabletop exercises, simulations, and live tests to validate your plans. Document the results and address any gaps found.
- Engage leadership. ISO 22301 requires visible leadership commitment. Your executive team needs to understand their roles in business continuity and actively support the BCMS.
- Engage a qualified consultant or certification body. ISO 22301 implementation can be complex, particularly the BIA and risk assessment components. Working with someone who has done it before saves significant time and avoids common mistakes.
