"American Power Conversion is honored to have been ranked within the top 10 most innovative companies by InformationWeek for our customer relationship management (CRM) achievements," said Brian Belleveau, CIO at APC. "By focusing our efforts toward the continuous improvement of the 'customer experience,' we have not only achieved improvement of the external facing processes but also the internal processes. In the end, it is all about the customer. We want to know as much about our customers as possible. The more we know, the better we can assist them in solving their business problems." In 2004, APC started a CRM transformation program. The goal was to continuously improve the customer's experience at every touch point and provide the level of service needed to achieve maximum customer satisfaction. The automated program was designed to track and report failed customer interactions and supply that data to the process improvement teams. This system gave these teams the opportunity to focus on what is truly needed to improve the value and experience we provide to our customers. "We'd like to extend our sincere congratulations to all InformationWeek 500 honorees. These companies represent today's leading technology innovators, many of whom have joined us this week," said InformationWeek publishing director, Fritz Nelson. "This group has prompted fascinating discussion on some of the most forward-looking business technology initiatives to date." For the past 18 years, InformationWeek has identified and honored the nation's most innovative users of information technology with its annual listing. The list is unique among corporate rankings because it spotlights the power of innovation in information technology, rather than simply identifying the biggest IT spenders.
