Fair Isaac's Blaze Advisor 6.5 Offers Greater Agility Throughout the Business Rules Lifecycle

Fair Isaac Corporation (NYSE:FIC), the leading provider of
analytics and decision management technology, today announced the
release and immediate availability of version 6.5 of Blaze Advisor(TM)
business rules management system, a core offering in Fair Isaac's
roster of technologies for Enterprise Decision Management (EDM).
Designed to help organizations increase the precision, consistency and
agility of their critical, high-volume decisions, Blaze Advisor 6.5
software provides businesses with enhanced support for managing rules
and analytics from development through deployment.

Industry-leading Blaze Advisor software allows non-programmers to
design, deploy, execute and maintain business rules and policies as
part of an automated business application. The software incorporates
the advanced Rete III inference engine that helps organizations manage
large amounts of data and execute rules faster and more efficiently
than other rules management systems.

Blaze Advisor 6.5 integrates new features to help business users
better verify and validate the completeness and consistency of rules
across the rules lifecycle, significantly increasing the accuracy and
reliability of the inferencing process.

According to Stephen D. Hendrick, group vice president for
industry analyst firm IDC's Application Development and Deployment
research group, "The business rule management systems market is poised
for rapid growth due to the compelling value proposition of
inferencing." While inference engines provide a high level of
flexibility, "the reliability of the inferencing process is a function
of how complete and consistent the business rules are. Most vendors
provide few or no capabilities to verify and validate the
completeness, consistency and coherence of the business rules"
("Business Rule Management Systems: Addressing Referential Rule
Integrity," IDC #201262, April 2006).

New capabilities include enhanced verification of rules and
procedural logic, such as user-defined functions to identify gaps and
overlaps. Users also can validate rules through regression testing
against expected values. The publication process including these
verification and validation steps as well as stakeholders' approval is
managed by Blaze Advisor 6.5 in the new Rules Lifecycle service.
Projects can be promoted from development to production according to
documented and automated processes.

In addition, version 6.5 features tight integration with Model
Builder for Predictive Analytics 3.5, Fair Isaac's software platform
for developing and deploying predictive models. The integration allows
for greater transparency and enables the swift and flexible movement
of models from data analysis into effective decision management via
Blaze Advisor's enhanced Predictive Model Markup Language (PMML)
import capabilities. PMML is the most widely deployed data-mining
standard for describing statistical transformations and predictive
models.

A scorecard, regression or neural network model built in Model
Builder can be directly deployed within Blaze Advisor rules flows
without recoding. Any authorized business user can apply analytics as
an essential decision element that can be seen, easily modified and
combined with other decision elements prior to execution, in a single
process.

"Blaze Advisor 6.5 integrates innovative and industry-proven
capabilities that further improve our clients' critical, high-volume
decisions," said Carole-Ann Matignon, vice president of Enterprise
Decision Management Technologies at Fair Isaac. "From comprehensive
support for moving business rules from development to production, to
helping businesses manage predictive models as part of their rules
repository, this latest version is designed to turn companies into
truly agile organizations that can intelligently adapt operational
decisions to the ever-changing demands of their business."

Companies in many industries and countries rely on Fair Isaac's
Blaze Advisor to support some of their most complex business
applications. The software is the first rules engine to support Java,
.NET and COBOL deployment of the same rules. The multi-platform
solution supports Web Services and SOA, Java 2 Enterprise Edition
(J2EE) platforms, Microsoft .NET, and COBOL for z/OS mainframes.
