Fair Isaac Spotlights Latest Strategies and Innovations for Smarter Decisions at InterACT 06

(San Francisco, California, USA) - Fair Isaac Corporation (NYSE:FIC), the leading provider of solutions and technologies for Enterprise Decision Management (EDM), kicked off its 2006 North American InterACT customer conference today in San Francisco. In his opening address, CEO Tom Grudnowski discussed how Fair Isaac's ongoing pursuit of innovation is breaking new ground to help organizations transform and improve the way they make their most critical decisions.

InterACT, the world's leading business forum on business analytics, emerging decision management technologies and their applications, is being held this week in San Francisco, where Bill Fair and Earl Isaac started the company in 1956. Registered attendance of nearly 700 for the company's 50th anniversary conference is the highest in several years, demonstrating the growth in demand for EDM strategies and solutions.

Grudnowski told InterACT delegates that they are among the leading practitioners of EDM, which combines the analytic solutions and decision automation software organizations need to make their decisions more precise, more consistent and more agile, at every customer interaction or decision point. He also recognized clients' central role over the past 50 years in turning the company's solutions for risk management, fraud control, account management, business rules management and more into industry standards.

"We are very fortunate to have clients who understand and value what this company was born to do - help organizations solve their most complex business problems by consistently making the right decisions at the right time," said Grudnowski. "We've been perfecting the science of EDM in our R&D labs, and working with you to perfect it in the form of thousands of successful deployments around the world. Bill Fair once said, 'We sell a radically different way of making decisions that flies in the face of tradition.' That was true in 1956, and it's still true today."
