Overview
JBoss Enterprise BRMS is an open source business rules management system that enables easy business policy and rules development, access, and change management. A business rules management system helps an organization capture and manage business knowledge and policies.
These business rules form the basis of decision-making in an organization.

JBoss Enterprise BRMS includes a fast and highly efficient rules engine and easy-to-use rules development, management system, and repository. JBoss Enterprise BRMS makes it easy for a business analyst or auditor to view and manage your business rules as encoded in your IT application infrastructure. Business analysts as well as SOA and rules developers can verify that the encoded rules
indeed implement the documented business policies. JBoss Enterprise BRMS also supports a variety of authoring and management consoles and language and decision table inputs, making it easy to quickly modify your business policies to respond to opportunities and competitive threats.

Benefits
JBoss Enterprise BRMS allows businesses to reduce development time to update applications, SOA deployments, and business processes with the latest business rules and policies. This enables enterprises to respond to business environment changes and rapidly update their IT applications
to feature new products and specials, offer current and relevant upsell offerings, and respond rapidly to competitive and business challenges. Something as simple as implementing new pricing scheme can be rolled into production in a matter of hours with little to no impact to the current application infrastructure.
