What Is the Difference Between Business Continuity and Operational Resilience?

The Short Answer

Business continuity and operational resilience are closely related, but they are not the same.

Business continuity focuses on maintaining and recovering disrupted operations. Operational resilience takes a broader view, focusing on an organisation’s ability to sustain important business services, adapt to disruption and avoid intolerable harm to customers, markets and other stakeholders.

Business continuity can therefore be regarded as an essential component of operational resilience, alongside areas such as risk management, cyber security, supplier resilience, incident management and crisis response.

Business Continuity and Operational Resilience Compared

What Is Business Continuity?

ISO 22301 defines business continuity as “the capability of the organization to continue delivery of products or services at acceptable predefined levels following a disruption.”

In practice, business continuity planning and analysis involves:

• Identifying the critical processes that contribute to key products and services
• Assessing how time-sensitive those processes are
• Setting appropriate recovery timeframes and priorities
• Assessing risks that could disrupt critical processes
• Identifying practical mitigations and recovery strategies
• Designing response structures and recovery plans
• Validating response arrangements through exercises and reviews
• Continually improving the organisation’s business continuity capability

Business continuity provides the practical arrangements an organisation uses to continue or restore priority activities following disruption. These arrangements may be formalised through an ISO 22301-aligned business continuity management system.

What Is Operational Resilience?

Operational resilience developed more recently as a distinct regulatory discipline, particularly through financial sector regulation and systemic risk management.

The Bank of England defines operational resilience as “the ability of firms and the entire financial sector to prevent, adapt, respond to, recover from and learn from disruptions.”

Operational resilience therefore adopts a broader and more outward-facing perspective. The emphasis is on the continued delivery of important business services and avoiding intolerable harm to customers, market integrity and the wider financial system.

This requires organisations to understand how disruption could propagate across interconnected:

• People and internal processes
• Technology and information
• Facilities and physical infrastructure
• Third-party providers and supply chains
• Customers, partners and wider markets

Rather than looking only at how an individual activity will recover, operational resilience examines how the organisation’s combined resources support the end-to-end delivery of an important business service.

How Do Financial Services Firms Demonstrate Operational Resilience?

The FCA, PRA and Bank of England do not certify firms as operationally resilient. Instead, firms within the scope of the UK operational resilience regime must demonstrate ongoing compliance and maturity.

This includes:

The FCA expects these arrangements to develop as risks, dependencies and business services change. Operational resilience is therefore an ongoing management discipline, rather than a one-off compliance project.

Does Operational Resilience Replace Business Continuity?

No. Operational resilience does not replace business continuity. It provides a broader framework within which business continuity performs an essential role.

Business continuity supplies many of the capabilities needed to respond to and recover from disruption, including business impact analysis, recovery strategies, continuity plans, crisis response structures and exercise programmes.

Operational resilience connects these capabilities with preventative controls, dependency mapping, customer harm, supplier assurance and strategic governance. An organisation cannot credibly claim to be operationally resilient if it lacks workable business continuity arrangements.

Is There an ISO Standard for Operational Resilience?

There is currently no single globally recognised certifiable ISO standard for operational resilience equivalent to ISO 22301 for business continuity management systems.

ISO 22316 provides guidance on organisational resilience, but it is not a certifiable management system standard. Organisations may also use related standards covering business continuity, risk management, information security, incident management and crisis management to support different elements of their resilience capability.

For financial services firms, operational resilience is principally demonstrated through compliance with relevant FCA, PRA and Bank of England rules and expectations.

Operational Resilience as a Broader Framework

Although the modern regulatory concept of operational resilience developed largely within financial services, its wider perspective can be useful for organisations in other sectors.

Operational resilience can bring together:

• Horizon scanning and threat intelligence
• Risk assessment and mitigation
• Business continuity and disaster recovery
• Cyber security and information resilience
• Supplier and supply chain resilience
• Incident and crisis management
• Dependency mapping and service ownership
• Scenario testing and organisational learning

This creates a cross-functional approach to managing operational risk across the organisation’s complete value chain.

How Can Organisations Assess Their Current Position?

An organisation must understand both the maturity of its business continuity arrangements and how those arrangements contribute to wider operational resilience.

An operational resilience and business continuity benchmarking assessment can establish a clear baseline, identify gaps and help senior leaders develop a practical improvement roadmap.

Organisations should also use appropriately challenging crisis simulation exercises to test whether plans, dependencies, decision-making structures and recovery strategies work under realistic pressure.

In Summary

Business continuity focuses on maintaining and recovering priority operations following disruption. Operational resilience looks more broadly at whether important business services can withstand disruption without causing intolerable harm.

The two disciplines are complementary. Strong business continuity arrangements provide a foundation for operational resilience, while operational resilience connects continuity with risk management, technology, suppliers, governance and the needs of customers and markets.
