Business continuity is an organisation's ability to keep its essential operations running, or restore them quickly, when something disrupts them. It covers planning for events such as cyber attacks, IT failures, the loss of a key supplier or loss of premises, so the business can keep serving customers and recover in an orderly way.
What business continuity is
Business continuity is about keeping the lights on when something goes wrong. The term covers both the state you're aiming for (operations that keep running) and the work you do to get there. That work is called business continuity management, or BCM - an ongoing discipline of identifying what could go wrong and preparing a proportionate response.
The output of that work is a business continuity plan: a written document that tells everyone what to do, who's in charge and how the organisation will recover. Crucially, BCM covers the whole business - people, premises, suppliers and IT systems - not only technology.
The international standard for business continuity management systems, ISO 22301, defines the requirements for a formal BCM programme and gives organisations a common framework to work from.
What a business continuity plan covers
A good plan addresses five areas: which activities are essential and must be protected first; who does what during a disruption and who has authority to make decisions; how the business communicates with staff, customers and suppliers; alternative ways of working when normal operations are unavailable; and the steps to return to normal once the disruption has passed.
The UK government's business continuity guidance also highlights the importance of understanding your dependencies - the suppliers, systems and premises you rely on - so your plan reflects the real shape of your organisation.
A plan that sits in a drawer and is never tested is close to worthless. Exercising the plan at least annually, and after any major change to the business, is what turns a document into a genuine capability.
Business continuity vs disaster recovery
These two terms are often used interchangeably, but they mean different things. Business continuity keeps the whole organisation functioning during and after a disruption - it covers people, premises, processes and technology. Disaster recovery is a narrower discipline focused specifically on restoring IT systems and data after a failure.
Think of disaster recovery as one chapter inside a larger business continuity plan. That chapter will typically include targets for how quickly systems must be back online - the recovery time objective (RTO) and recovery point objective (RPO) - but the wider plan addresses everything else the business needs to keep running alongside the IT.
Why it matters for a smaller business
Smaller businesses are often hit harder by disruption than larger ones because they have less slack: fewer people to cover for absent colleagues, fewer alternative suppliers and tighter cash reserves. A few days of lost revenue or an inability to serve customers can have consequences that take months to recover from.
Clients, insurers and larger customers increasingly ask for evidence of continuity planning before signing contracts. Understanding your risks through a business impact analysis is the practical first step, and it feeds directly into the plan you'll produce. This all sits within the broader discipline of IT governance, which gives the whole effort its structure and accountability.
ISO 22301 certification is not a legal requirement, and formal certification isn't necessary for most SMEs. A proportionate, well-tested plan built on sound principles is achievable without it. Our incident response guide covers the practical steps for when something does go wrong.
