Prevention
Steps needed to help prevent systems failure are the same, no matter the size and scale of the company involved.
The following bullets provide a high level guide to preventing (or at least, reducing the likelihood of) systems failure. More detailed measures can be found in our Business Continuity Management section.
Basic steps for prevention:
- Perform a risk analysis. This can be a sophisticated and extensive exercise, but it is essential to:
- Establish the importance of each system or system element
- Work out what could stop them operating.
- Implement appropriate controls to minimise the disruption caused by any untoward event.
- Take regular backups of information and store them away from the system. Establish how long your company can tolerate a system failing (a day, a week?) and make sure your backups allow you to recover before that time elapses.
- If you hold sensitive information, remember to apply appropriate security to your backup media
- Make sure you have access to alternative machines to run your systems and hold your data should you lose premises through a catastrophic event, such as a flood or a fire.
- Consider making a mutual support agreement with another organisation, preferably one that is unlikely to suffer from the same event as yours (i.e. they aren't next door, they use a different power supply, and they won't be flooded by the same river).
- Make arrangements with hardware suppliers for rapid installation if you are running a time-sensitive operation. Some companies specialise in providing support premises and equipment, normally on an annual charge basis (a bit like an insurance policy).
- Establish sound fire prevention and detection systems. You should also consider looking at water detection systems, especially if you operate in a high-risk flood area.
- Environmental risk should form part of your initial risk analysis. Environmental issues should include:
- Investigating neighbouring industrial concerns, to see if they carry a high-risk (for example, a chemical works).
- Investigating neighbouring companies to see if they might be the targets of civil unrest (for example, animal testing, nuclear power, etc).
- Checking local conditions by contacting the local authority, who normally have information on environmental risks and often make a local emergency plan available.
- Look for single points of failure. These can be telephone exchanges, power supplies and road transport links. If you are dependent on a single supplier for key goods or services, make sure you know who they are.
- Having identified single points of failure, look for alternative suppliers, or seek insurance against them failing.
- Consider a UPS (Uninterruptible Power Supply), as these not only reduce the impact of a real event, but also protect your computer systems against voltage spikes that can corrupt data even if they don't take your system down.
- Be aware of the details of any software support contracts. If you need specialist help at 4am on a Saturday, you may find yourself in trouble if you haven't made provision for it.
- Make sure you have appropriate licences and support agreements in place for all hardware and software. Try to avoid invalidating any warranty agreements, as this can severely hamper support.
- Make sure all staff know what to do in an emergency and that they have the means to contact you if getting to the office is made difficult or hazardous.
