It accomplishes this by simplifying enterprise applications and basing them on modular components that have access to a complete set of reusable services. It also hides many details of application behavior automatically, without complex programming. Positioned as just another reusable service, the rule engine could take enterprise applications to the next level by isolating the business logic that often requires change.
