The IT services sector witnessed its worst year in a decade in 2012, according to a study from Ovum that found the value and volume of deals were at their lowest level since 2001. Analysts blamed the decline in part on a pullback in investments from the enterprise sector. "Our research suggests that many enterprises remain wary of committing to major projects, with issues such as the eurozone crisis having a particularly significant impact," said Ovum's Ed Thomas.
