What it means
Every business faces unexpected events that threaten daily operations. A business continuity plan acts as an insurance policy for your processes, ensuring you are not guessing what to do when a crisis hits.
It identifies critical functions, such as payroll or customer service, and maps out alternative ways to run them if your primary office or software becomes unavailable. For non-finance managers, understanding this plan is vital because disruptions directly impact the bottom line.
When operations halt, revenue stops, but fixed costs like rent and salaries keep piling up. Knowing your role in the plan helps minimise downtime, protect profit margins, and reassure stakeholders that the business remains stable under pressure.
In practice, creating this plan involves assessing potential risks, setting up backup systems, and training team members on their specific duties during an emergency. It connects operational readiness with financial survival.
By preparing in advance, managers prevent temporary emergencies from turning into permanent closures. A business continuity plan is like the emergency fire drill you practised at school.
You hope you never have to use it, but everyone knows the exit routes so that panic is avoided and safety is maintained if the alarm actually sounds.
In practice
Real-world examples
Example 1
An e-commerce startup experienced a warehouse fire that destroyed inventory. Thanks to their continuity plan, they quickly shifted fulfilment to a partner warehouse, resuming online orders within 48 hours and limiting revenue loss to 5%. Customers received emails explaining the short delay.
Example 2
A regional accountancy firm faced a major ransomware attack locking their client databases. Their continuity plan enabled an immediate switch to secure offsite cloud backups, allowing staff to process tax returns without missing critical deadlines. Staff knew from earlier drills who to call and what to do first.
Example 3
A manufacturing SME suffered a prolonged power outage during a severe storm. Their continuity plan included a pre-arranged backup generator contract, keeping the assembly line moving and saving $10,000 in spoiled raw materials. The generator supplier had already agreed the price and delivery time.

Formula
Calculation
Business Impact Score = Financial Loss per Hour ($) x Estimated Downtime (Hours)
Loss per Hour = Lost gross margin per hour + Continuing fixed costs per hour
Example: If a system outage costs your firm $500 per hour and takes 6 hours to fix, your Business Impact Score is $3,000 ($500 x 6). This helps you decide how much to invest in backup systems.
Worked example 2. A business sells $2,000 of goods an hour at a gross margin of 40%, so it loses $2,000 x 40% = $800 of margin for every hour it cannot trade. Its fixed costs of rent and salaries still run at $300 an hour. Loss per hour = $800 + $300 = $1,100. A 6-hour outage costs $1,100 x 6 = $6,600. If the continuity plan lets the firm switch to a backup system within 1 hour, the loss is $1,100 x 1 = $1,100, which saves $5,500 per incident. If the backup service costs $2,000 a year, one incident in the year pays for the plan almost three times over ($5,500 / $2,000 = 2.75). Some lost sales may be recovered later, so the true loss can be a little lower, but fixed costs are never recovered.Case study
Seen in the real world
This is a fictional, illustrative scenario. Brighton Bakery, a medium-sized wholesale food business supplying local cafes, faced a crisis when their main delivery van fleet was immobilised by flash floods. Because operations manager Sarah had implemented a solid business continuity plan, the company did not panic. The plan immediately activated a pre-arranged agreement with a local logistics partner who provided replacement vans and drivers within three hours.
Furthermore, the administrative team switched to a cloud-based ordering system accessible from home, bypassing the flooded headquarters. Out of twenty daily delivery routes, nineteen were completed on time. The total cost of activating the backup transport agreement was $1,200, which was far less than the $15,000 in potential lost sales and damaged client relationships if deliveries had failed completely. This proactive approach kept cash flowing and preserved the company's reputation for reliability.
After the floods Sarah reviewed what had worked. Nineteen of twenty routes is 95% on time, and the $1,200 cost bought protection of $15,000 of sales, a ratio of 12.5 to 1. The one missed route was traced to a customer who had not been told about the temporary drop-off point, so she added a customer notification step to the plan. She also scheduled a half-day drill every six months so the logistics partner's drivers know the routes.
Watch out
Common mistakes
- Treating the plan as a one-time project and never updating contact details or software steps.
- Focusing entirely on IT disasters while ignoring staff safety and physical supply chain risks.
- Failing to test the plan through regular dry runs or mock crisis simulations.
Questions
People also ask
Who is responsible for creating a business continuity plan?
It is typically a team effort involving senior leaders, operations managers, IT staff, and finance leads, ensuring every departmental need is covered.
How often should we review our continuity plan?
You should review and update the plan at least once a year, or immediately whenever your business moves locations, changes key software, or launches new products.
Is a business continuity plan the same as disaster recovery?
Disaster recovery focuses specifically on getting computer systems and technology back online, while a business continuity plan covers the entire organisation and its core operations.
