Fair Isaac Recognized as Business Rules Management Systems Market Leader for Second Consecutive Year

(Minneapolis, Minnesota, USA) - Fair Isaac Corporation (NYSE: FIC), the leading provider of analytics and decision management technology, announced today that analyst firm IDC has recognized Fair Isaac as the worldwide revenue leader in the Business Rules Management Systems (BRMS) software market for the second consecutive year.

The new IDC report "Worldwide Business Rules Management Systems 2007-2011 Forecast and 2006 Vendor Shares" (IDC #208989, October 2007) ranks Fair Isaac as the worldwide BRMS market leader in 2006 with revenues of USD 53,5 million, compared with revenues of USD 45,1 million in 2005. IDC credits Fair Isaac's 18,7 percent growth and 23,6 percent market share to the company's continuing success with its Blaze Advisor™ business rules management system in the North American market. Fair Isaac's revenue in North America was USD 45,1 million, compared to USD 24,4 million for the closest competitor.

According to the IDC report, the worldwide BRMS market witnessed double-digit growth in 2006 with revenues of USD 226,8 million, and is projected to grow to USD 530,8 million in 2.011,1

"Advances elsewhere in the application development and deployment markets are helping set the stage for even higher BRMS growth as the industry retools its approach to application development around deployment, support of standards, ease of construction, maintainability, and extensibility," said Stephen D. Hendrick, group vice president for

IDC's Application Development and Deployment research group. "Business rules engines are expected to become key development elements of the application infrastructure stack."

IDC defines business rules management systems as tools that centralize the definition, discovery, storage, and submission of the vast quantity of rules used in business operations to provide organizations with greater automation, more responsiveness to change, and less expensive distribution and maintenance of their business activities.2

"The continued success of Blaze Advisor is really a testament to our customers worldwide who use it every day to manage their critical business rules and support smart decisions," said William Waid, vice president, Enterprise Decision Management Technologies, at Fair Isaac. "Being named the clear market leader by IDC for the second straight year also demonstrates our continued investment in and commitment to Blaze Advisor as a cornerstone of our Enterprise Decision Management suite of software and services."
