How to prepare for an ISO 22301 audit

Gavin Watt, Senior Resilience Consultant, explains why it takes more than documentation to demonstrate resilience in an ISO 22301 audit. 

The word audit can make most organisations uneasy. It often brings to mind scrutiny, pressure and the risk of uncovering gaps, especially when finances or compliance are involved. 

But a business continuity audit shouldn’t feel the same. 

For organisations with an ISO 22301 aligned business continuity management system (BCMS), an audit is less about being caught out, and more about proving your resilience works when it matters. 

As a resilience consultant and an ISO 22301 Lead Auditor, I consistently see that the hardest aspect isn’t achieving certification but maintaining the BCMS moving forward. 

What is ISO 22301? 

ISO 22301 is the international standard for business continuity management. It provides a framework for identifying critical activities, assessing risks, planning for disruption and improving organisational resilience over time. 

An ISO 22301 audit assesses whether your business continuity management system (BCMS) meets the standard’s requirements and is working in practice. Auditors look for evidence that business continuity is maintained, reviewed and improved over time. 

It’s not all about the documentation 

A common pitfall when preparing for audit is an over-reliance on documentation – business continuity plans (BCPs) and policies. 

Yes, these are essential. But on their own, they don’t demonstrate resilience. 

A BCP that isn’t understood, tested and kept up to date is unlikely to hold up during a real incident. True resilience comes from how well these plans are embedded into day-to-day operations and decision-making.

ISO 22301 isn’t about producing documents – it’s about ensuring your organisation can continue to operate during disruption and recover within acceptable timeframes.

Business continuity can’t sit in a silo. Strong leadership involvement is critical.

What do ISO 22301 auditors really look for? 

To prepare for an ISO 22301 audit, organisations need to demonstrate that business continuity is embedded across the organisation, not just documented. 

That means being able to evidence: 

 A clear understanding of your organisation 

 Leadership that’s genuinely engaged 

 A joined-up approach to risk and planning 

 People who know what to do  

 Plans that work in the real world 

 Ongoing review 

 Continuous improvement in practice 

 

A clear understanding of your organisation

Auditors want to see that you understand your organisation’s operating environment – its risks, dependencies, stakeholders and regulatory obligations. 

This includes having a clearly defined BCMS scope that reflects what truly matters to the business. If the scope is vague, overly broad or not aligned to critical services, it quickly raises concerns about how effective the BCMS can be in practice. 

Leadership that’s genuinely engaged

Business continuity can’t sit in a silo. Strong leadership involvement is critical. 

Auditors will look for evidence that senior management are actively driving and supporting the BCMS, not just signing off policies. This includes owning the business continuity policy, setting direction, allocating resources and participating in management reviews. 

Without visible leadership commitment, it’s difficult to demonstrate that resilience is embedded across the organisation. 

A joined-up approach to risk and planning 

Your risk assessment (RA), business impact analysis (BIA) and business continuity objectives should all connect. 

Auditors will expect to see a clear process for identifying risks and opportunities, and how these translate into defined business continuity objectives. They will also look for alignment between your risk register, BC policy and continuity plans. 

A well-structured approach shows that your organisation is not only managing risk but continually improving its resilience. 

People who know what to do

In a disruption, clarity matters. 

Auditors will assess whether people understand their roles and responsibilities during an incident, know how they will be contacted and can access the information they need. 

This is supported by role-specific training, clear communication processes and organisation-wide awareness. Embedding business continuity into onboarding and regular training programmes helps to ensure that preparedness is visible across the business. 

Plans that work in the real world

Your BIA and RA form the backbone of your BCMS. They identify your critical activities and define how quickly they need to be recovered. 

Auditors will examine how these are developed, whether recovery objectives are justified, and whether they are regularly reviewed – at least annually or following significant business change. 

From there, your business continuity and incident management plans must bring this to life. They should be: 

  • Aligned to the BIA  
  • Up to date  
  • Practical and easy to follow under pressure  
  • Accessible during an incident  

Auditors will also assess whether your exercising programme is effective. Regular testing is expected, but more importantly, organisations must demonstrate that lessons are identified, actions are taken, and improvements are made over time. 

Ongoing review 

A BCMS isn’t static – it needs to evolve with the organisation. 

Auditors will expect evidence of internal audits, management reviews and performance monitoring to ensure the BCMS remains effective. 

They may also review how your organisation has responded to real incidents, whether plans were effective, recovery objectives were met, and what lessons were learned. This feedback loop is key to maintaining resilience. 

Continuous improvement in practice 

No BCMS is perfect, and auditors don’t expect it to be. 

What they do expect is a clear approach to managing nonconformities and corrective actions. This includes identifying issues, addressing root causes and evidencing improvements. 

Strong organisations can demonstrate how lessons from exercises and real incidents feed directly into updates to plans, processes and strategy, ensuring the BCMS continues to mature over time. 

One rule above all 

There’s a simple truth that applies to any audit: 

If you can’t evidence it, it didn’t happen. 

It’s not enough to say you test plans or review risks – you need clear, consistent records to support it.

ISO 22301 isn’t about producing documents – it’s about ensuring your organisation can continue to operate during disruption and recover within acceptable timeframes. 

Final thought 

An ISO 22301 audit shouldn’t be something to fear. When the right foundations are in place, it’s a valuable opportunity to validate your organisation’s resilience. 

If business continuity is embedded in your culture, supported by leadership, regularly tested and continuously improved, the audit becomes far less daunting – and far more meaningful. 

Ultimately, ISO 22301 focusses on resilience. How is your organisation going to maintain its critical functions and “keep the lights on” during a disruption, and how quickly and effectively can the organisation recover? This is not achieved by just words on paper.
