Business Rules Management 
SAP NetWeaver Business Rules Management (SAP NW BRM) enables organizations to automate decisions by using business rules. Business users participate in and control rule definition, while business process experts model, validate, deploy, update, and archive business rules through their lifecycle. As such, IT organizations can work with business users to manage business rules that drive process flow and execution.
Business rules describe the operation, definition, and constraints that apply to an organization in achieving its goals.
SAP NW BRM provides the following:
Rules Composer: This is integrated into SAP NetWeaver Developer Studio as a separate perspective and provides rich and user-friendly formats of rules representation enabling users to model complex business rules. It contains extensive business rules modeling capabilities for business analyst and rules implementation functionality for business rules developers.
For more information, see Modeling Rules with Rules Composer.
Rules Manager: Rules Manager is a rule-centric application, based on SAP's Web Dynpro technology that provides a rule management environment. It allows business managers, administrators, functional users to modify business rules and effect changes in real time.
