This diagram shows the history and current state of business rules technology vendors. Today's "business rules engines" were previously known as "expert systems". The Artificial Intelligence-based inference engine under the hood is what gives these products the power to fire the rule at the right time. As you can see, some of these products have been around for 20 years or so.

Haley Systems should be on your BRE short-list if your business users want to write natural language business rules - in English.

ILOG was one of the first expert system companies. Their first product was written in LISP. Today their rule engine is written in Java and .NET. Their history is as follows:

1987 Founded
1988 LISP Rule Engine
1993 ILOG Rules (C++)
1997 ILOG JRules (Java)
2001 JRules 3.5 (XML/J2EE)
2002 JRules 4.0 (BRMS)
2003 JRules 4.5
2004 Rules for .NET

InRule should be on your BRE short-list if you need a fast .NET rule engine.

Versata used to be known as Vision Software. Their rule engine is optimized for data-intensive transactional applications.

Pegasystems is one of the new generation rules/process engines that have taken expert systems to the next level by combining workflow and process automation.

Insession Technologies is another new generation rules/process engine that combines the features of rules, workflow, and process automation with logical rules/process modeling.

RulesPower also combines the features of rules, workflow, and process automation with logical rules/process modeling. In November 2005, RulesPower was acquired by Fair Isaac
