MINNEAPOLIS -- Fair Isaac Corporation (NYSE:FIC), the leading provider of analytics and decision management technology, announced today that IDG's InfoWorld, the leading integrated media brand for strategic technology decision-makers, has honored Fair Isaac with the 2007 Technology of the Year Award for Best Business Rules Management System (BRMS).

Fair Isaac's Blaze Advisor[TM] business rules management system is an industry-leading software package that allows design, deployment, execution and maintenance of business rules and policies as part of an automated business application, helping businesses reach new levels of agility in an increasingly complex, competitive and regulated global economy.

InfoWorld's annual Technology of the Year Awards recognize the top technologies that made the greatest impact on enterprise IT strategies during the past year. They also identify the products that best exemplify the implementation of those technologies.

According to the InfoWorld Test Center analysts and editors, "Blaze Advisor has always been one of the most friendly of the BRMS tools to business users, providing pleasant graphical development environments and understandable rule flow charts, decision tables, rules trees, and object models. Version 6.1, thanks to the incorporation of Rete III, now moves Blaze into the front of the pack in performance."

Fair Isaac's Blaze Advisor system gives business analysts policy control of implementing new legislation, while its flexible standards-based architecture simplifies development efforts by seamlessly integrating with existing systems and data. The latest release of Blaze Advisor includes the advanced Rete III inference engine for best-in-class performance within complex, enterprise-class deployments and powerful rules management capabilities.

"InfoWorld's recognition of Blaze Advisor as the top enterprise business rules management system is a testament to an increasing appreciation for the system's unique capabilities and the measurable business benefits it delivers," said Carole-Ann Matignon, vice president of product management, Enterprise Decision Management Technologies at Fair Isaac. "More businesses are realizing the value of a more sophisticated, enterprise-level approach to their critical decision processes, and Blaze Advisor provides a strong foundation for a decision management approach that drives improved efficiency and greater profitability."

Blaze Advisor 6.1 is part of Fair Isaac's software and solutions for Enterprise Decision Management, which combines data analytics, modeling, and policy-level control to let companies define and manage their automated business systems with increased agility, consistency and precision.
