To understand the customer experience delivered by IT vendors, we surveyed 800 IT professionals from large companies. Using their feedback on the functional, accessible, and emotional components of experiences with vendors, we created the 2012 Temkin Experience Ratings for Tech Vendors which rates 60 large IT suppliers by their customers. Microsoft business applications, Cisco, IBM SPSS, and Microsoft servers were at the top of the list with “excellent” ratings. At the other end of the spectrum, Compuware, Capgemini, and Fujitsu were at the bottom of nine companies with “very poor” ratings. Our research also looked at the 2012 purchase plans for these IT buyers. When we chart the Temkin Experience Ratings for Tech Vendors with the purchase momentum for these 60 firms, it shows the clear connection between customer experience and revenues.
