One in 6 large IT projects go over-budget by an median of 200%, according to new research.
The investigate by Oxford University and McKinsey moreover found that spending on technology was 3 times more expected to turn out of manage than building or other leading projects.
Researchers mentioned that singular but high-impact problems, dubbed "black swans", were frequently to blame.
They can lead to cost over-runs able of bankrupting exposed firms.
The investigate analysed 1471 large-scale universal IT projects costing more than $170m.
It found that whilst many projects ran reduction than 30% over budget, a sixth finished up costing on median 3 times as much.
The investigate moreover lifted concerns about the satisfactoriness of normal risk-modelling systems to cope with IT projects, with large-scale P.C. spending found to be 20 times more expected to turn out of manage than expected.
Researchers put this down to "black swan blindness" - a bent for IT decision-makers to disregard low luck but high-impact risks to plan plans.
"Black swans are disastrous events that strike you rarely, but when they strike you, they do it with a large impact," mentioned Professor Bent Flyvbjerg of Oxford University.
"IT managers lend towards not to see these black swans, since they pretence that they're rare, and will may come about to somebody else. They are wrong. They come about sufficient more frequently than people think."
The highbrow cited UK definite Auto Windscreens as an e.g. of a plan that had spun out of control, with inauspicious results is to business.
"It was the second largest windscreen repairer in the country. They attempted to exercise a new IT system, but it misfired - developing outrageous problems," he said.
Auto Windscreens went in to administration department in February.
"Black swans frequently beginning as quite program issues. But then a few things can come about at the same time - mercantile downturn, financial difficulties - that combination the risk," explained Prof Flyvbjerg.
Until now, large-scale program failures have been many related with the open sector. In 2007, a European Services Strategies Unit inform identified 105 UK open zone contracts with significant cost overruns.
However, Professor Flyvbjerg believes these problems request similarly to in isolation firms.
"People always think that the open zone was carrying out worse in IT than in isolation companies - our commentary indicate they're only as bad.
"We think supervision IT contracts obtain more attention, whereas the in isolation zone can conseal its details," he said.
Professor Flyvbjerg and his group are right away seeking to rise collection that help IT managers prevent out-of-control projects.
"Managers are really expected to run in to black swans. They must be able to pick out them and prevent them."
