The widespread acceptance of Service-Oriented Architecture (SOA) proves that enterprises have realized the promise of this technology. That promise of increased agility comes from a basic software design principle: loose coupling. SOA allows for business functions to be exposed as independent services. Web services, which is one way to implement SOA, makes any business functionality available over the Internet. Another technology that promises to extend that agility to business users is Business Rules Management (BRM) systems. A BRM gives business users direct control over the business logic, allowing them to change it without much intervention from IT. This paper explores how these two technologies - SOA and BRM - promise to help businesses respond more quickly and cost effectively to changing market conditions.
