Research Slideshow: Vendors That Deliver, Vendors You Can Trust

Each year, we poll CIOs and other leading IT decision-makers about the value of their IT vendors. This year, nearly 700 qualified respondents participated in our survey, rating the top 40 IT vendors on a range of metrics, including value, reliability and loyalty. After identifying the vendors with which their enterprise has had a business relationship in the past 12 months, respondents were asked to rate those vendors on seven criteria. The ratings are derived for each vendor from the average percent of "good" or "excellent" responses they received for each criterion. In addition, respondents were asked whether, given a choice, they would continue to use each vendor with which they currently work - a telling testament to which companies can boast the best customer loyalty. Check out which vendors were ranked tops in each of these categories. For more, read the complete report, CIO Insight 2010 Vendor Value Ratings.
