The Forrester Wave™: Business Rules Platforms, Q2 2008

Forrester evaluated 13 platforms from 11 vendors using 175 criteria and found ILOG JRules, Fair Isaac Blaze Advisor, and Pegasystems PegaRULES to be resounding Leaders as general-purpose business rules platforms. Haley Limited (Haley Expert Rules), Corticon Technologies, and Innovations Software Technology also emerged as Leaders, and InRule Technology followed close behind. But choosing a business rules platform is not as easy as simply picking one of the Leaders. To help application development pros understand these choices, Forrester created five views of the business rules market, including: general-purpose platforms, specialized platforms (from Experian, Intelligent Results, and Haley Limited's Haley Office Rules and Determinations Engine), platforms for Java application developers, platforms for .NET application developers, and platforms for business analysts who develop and maintain applications.
