Employees may be unable to work, customers may experience delays and important business processes can be interrupted. Depending on the organisation, even a relatively short outage can have consequences that extend well beyond the initial disruption. Understanding these wider costs is an important part of planning IT resilience.
One of the most immediate effects of downtime is the impact on employees. If essential systems become unavailable, staff may be unable to access information, communicate effectively or complete their usual tasks. Consider a business with 30 employees who depend on a particular system. If that system becomes unavailable for two hours, the organisation could lose up to 60 hours of productive working time, assuming all 30 employees are prevented from working throughout the outage.
The actual impact will depend on whether alternative tasks are available and how quickly employees can resume normal operations. Nevertheless, it demonstrates how a relatively short interruption can affect productivity across an organisation.
Technology problems don’t always remain behind the scenes. If employees cannot access customer records, process orders or respond to enquiries, customers may experience delays.
For organisations that rely on online services or connected payment systems, an outage could also affect their ability to trade. The financial consequences will vary, but customer frustration and disruption can create additional challenges.
Some costs are harder to calculate:
These situations may not create an immediate invoice or repair bill, but they can still affect business performance, and where organisations depend on several connected systems, the impact of one failure may spread into other activities.
Another consideration is the time required to restore normal operations. Even when the initial technical issue has been resolved, employees may need to reconnect to systems, verify information or repeat work that was interrupted.
In some circumstances, additional checks may be required to confirm that systems and data are functioning correctly. That’s why recovery planning should consider more than simply restoring access. Organisations also need to understand what happens afterwards.
There are many potential causes of technology disruption.These include:
Not every incident can be prevented. However, understanding the most likely risks and their potential impact can help organisations make better decisions about resilience.
A useful starting point is identifying which systems your organisation depends on most. For example:
These questions help establish priorities. Not every system needs the same level of resilience, and the cost of protection should be proportionate to the potential business impact.
Backups are an essential part of protecting business information, but they are only one element of recovery planning. Organisations also need to consider how quickly systems could be restored and what resources would be required.
Two useful concepts are:
Recovery Time Objective (RTO)
The target amount of time within which a system or service should be restored following a disruption.
Recovery Point Objective (RPO)
The maximum amount of data loss, measured in time, that an organisation considers acceptable.
For example, a business may decide that a critical system needs to be restored within four hours and that losing more than one hour of data would be unacceptable. These targets help inform decisions about backups, infrastructure and recovery arrangements, and they should reflect actual business requirements rather than being selected arbitrarily.
Reducing downtime risk doesn’t necessarily require replacing every system or making significant new investments.
A practical approach might include:
The right approach will depend on the organisation, its technology and the potential impact of disruption.
Every organisation experiences technology problems from time to time. The difference is often how prepared it is to respond.
Understanding which systems matter most, what an outage could cost and how recovery would be managed can help organisations reduce unnecessary disruption, and these are questions worth considering before something goes wrong.
