Cognos Named Editors’ Choice for Performance Management by Intelligent Enterprise

— Company lauded as one of the 12 most influential
for the 4th consecutive year —

BURLINGTON, MA, March 16, 2005 — Cognos (NASDAQ: COGN; TSX: CSN), the world leader in business intelligence and corporate performance management (CPM), today announced that it has been named “Editor’s Choice” for Performance Management by the editors of Intelligent Enterprise (IE) magazine.

The magazine’s 7^th annual editors’ choice evaluation cited Cognos over four other companies as the top company to watch in 2005 for performance management.

“Racing quickly to the forefront of enterprise reporting, Cognos' service-oriented ReportNet has been a big success. Brought together with the company's analytic software, Cognos makes the short list when companies look to consolidate onto an enterprise BI platform. Yet, all of this has been but a prelude to a decided turn toward performance management (PM). Marrying its strength in Web-based BI with new releases for planning and consolidation, metrics and scorecards, Cognos is positioned to be the pied piper of operational PM in 2005,” writes editorial director David Stodder in the April issue of Intelligent Enterprise.

Cognos was also named to the magazine’s 12 Most Influential Companies of 2005 list, a distinction Cognos has maintained for the past four years in succession. Commonly referred to as “The Dozen," this highly anticipated, annual editorial selection is determined by the senior editorial staff at IE on the dozen most influential vendors that provide exceptional vision, technology innovation and customer leadership in attaining the objectives of the intelligent enterprise.

“We are extremely proud to have been selected by Intelligent Enterprise for both distinctions. These distinctions are a testament to our continued innovation, portfolio-strength and success in partnering with customers to deploy market-leading performance management solutions across their enterprises,” said David Kleinhans, vice-president, Performance Management, Cognos Inc.
