Here's one of life's little ironies: A recent study finds that business leaders unhappy with their in-house IT shops are more likely to increase their spending on new technology. In fact, according to 437 execs interviewed by Forrester Research at a variety of businesses and industries across the country, the less-than-thrilled are growing their IT spending this year at twice the rate of their more-satisfied counterparts. The survey found that 34% of the respondents were dissatisfied with their IT shops' performance. Those also were the offices that tended to be technology laggards and where there tended to be more turf struggles and less of a focus on improving products and processes. The Forrester researchers found that happy campers tend to be those who focus on improving productivity and product and process quality rather than simply aiming to cut costs.
