Cognos Wins Prestigious Customer Support Award for Outstanding Performance and Innovation

– Cognos sole five-time winner of prominent industry honor –

BURLINGTON, MA, May 18, 2005— Cognos (Nasdaq: COGN; TSX: CSN), the world leader in business intelligence and corporate performance management (CPM), today announced that its Global Customer Services Web site (http://support.cognos.com) has been recognized as one of the Ten Best Web Support Sites of 2005. The prestigious industry award is given by the Association of Support Professionals (ASP), an international organization dedicated to the advancement of the technical support profession.

This is the fifth time that the Cognos Global Customer Services Web site has been named to the annual Ten Best list and the ninth award for online customer support excellence that the Web site has garnered in the past five years. Cognos is the only five-time winner of this award and is a member of the ASP’s Hall of Fame for Web Support Sites.

The annual “Ten Best” list judges customer support Web sites based on overall usability, design and navigation, knowledge base and search implementation, personalization, interactive features, as well as how they addressed a major site development challenge. Cognos shares this year’s award with technology leaders such as Cisco Systems, Microsoft, and BEA Systems.

“By continuously offering new ways for customers to generate greater value from their Cognos solutions, the Cognos Support Web site serves as a ‘model of how to deliver support on the Web’,” said ASP executive director Jeffrey Tarter. “The Cognos Global Customer Services Web site is a forerunner in online customer support innovation and excellence. Cognos is clearly a technology leader driving some of the most sophisticated advances in the Web support field.”

The success of the Cognos Global Customer Services Web site is based on Cognos’ commitment to fostering knowledge and innovative tools such as Cognos Support Accelerator, a secure Web-based utility that automates the timely and accurate collection of diagnostic information during support case submission. In addition, by giving customers access to a living store of multimedia information and tips, knowledge base content and self-service support options on the Support Web site, Cognos helps customers achieve success.

“Being named by the ASP to the ‘Ten Best’ Web Support Sites list is a tremendous honor and a huge credit to Cognos’ dedicated and talented staff of customer support professionals,” said Dave Achtemichuk, Cognos vice president of worldwide customer services. “Cognos is an organization dedicated not only to delivering industry-leading solutions but being a total business partner with our customers. The Cognos Global Customer Services Web site is a powerful extension of that ongoing vision.”
