SANTA CLARA, Calif., March 9, 2005 -- Hyperion (Nasdaq:HYSL), the global leader in Business Performance Management software, last week hosted an Executive Symposium that invited business advisors from the Hackett Group, an Answerthink company (Nasdaq:ANSR), to meet with senior finance executives from leading organizations and discuss top initiatives for Business Performance Management.

Hyperion customers, including Agilent Technologies, Coherent and Symantec, participated in this opportunity for strategic visionaries and decision makers to share best practices for Business Performance Management among their non-competitive peers.

"As companies increasingly face changing business issues, such as compliance and market consolidation, timely access to information and visibility across the enterprise is critical," said Kevin Guthrie, sales director for Hyperion. "This forum provided a venue for leading organizations to discuss how Business Performance Management can transform the way companies assess and act on information -- enabling them to react to market changes in real-time and stay competitive in today's dynamic marketplace."

Richard T. Roth, Hackett Group chief research officer, presented Hackett-Certified(SM) practices and metrics of world-class business performers -- organizations that have implemented and perfected best practices to help achieve overall exceptional performance -- for the benefit of the attendees. Roth also highlighted the importance and benefits of having access to on-demand performance metrics and best practices advice.

According to The Hackett Group, leading finance organizations spend 31 percent less money than their peers on operations and also utilize nearly half the staff -- enabling them to close their books more quickly and provide more meaningful insights to successfully drive their companies' performance.

"Several key strategies that world-class performers utilize to achieve exceptional results center around improving access to information and that can be done through Business Performance Management," Roth said. "For example, world-class finance organizations are 46 percent more likely than their median peers to use a central data repository to generate reports. They are also significantly more likely to have fully integrated budgeting and planning applications, and to use interactive tools, such as dashboards, enabling self-service for inquiries and financial reporting.

"Finally, they are 159 percent more likely to use mature balanced scorecards with a mix of financial and non-financial metrics to analyze performance."

According to Roth, these Business Performance Management strategies add up to greater insight, and improved ability to predict and manage performance and ultimately a company's bottom line.

The Hackett Group is a world leader in best practices research and process benchmarking, helping executives achieve significant and sustainable progress towards world-class performance through empirically based analysis and advisory services. Hackett's continuously updated knowledge repository is derived from 3,300 empirical studies over 13 years with more than 1,865 of the world's leading companies, including 93 percent of the Dow Jones Industrials.
