Almost two thirds of UK businesses are well prepared for serious IT failure, according to a survey of top companies by BSI British Standards.
The survey of FTSE 250 companies found UK businesses were increasingly prepared for disruption or disaster.
Most companies (81%) said they could last up to a week before feeling serious detrimental effects of disruption or disaster and 47% were prepared for supply chain failure.
The survey also found 71% recognised the importance of business continuity management (BCM) in staying competitive and winning new business, a 10% increase in the past year.
"The scale of risk and opportunity in the FTSE 250 are enormous and these organisations are recognising that BCM has to be at the heart of their operations," said Mike Low, director of BSI British Standards.
The findings were made public on the same day as the publication of the certification requirements for the new business continuity management standard, BS-25999 by BSI British Standards.
"Without BCM standards in place, infrastructure and supply chains may be less secure and employment and economic growth placed at risk," said Chris Green, chairman of the Business Continuity Institute.
UK business continuity practitioners have welcomed the publication of the specification, saying the standard will give companies clear guidelines on putting together a continuity plan as well as a clear benchmark to achieve.
The survey showed that events of the past year had prompted many businesses to reconsider their approach to BCM, with 42% doing so after the London and Glasgow terror alerts in June and 34% after the widespread flooding this summer.
