Business Rules Management (BRM)

Why Business Rules Management?

Externalize business rules from application code

Encapsulate rules as re-usable services

Increases flexibility, efficiency and control

Management and monitoring of rules is a critical

component of BPM

Serving business and IT

Why NetWeaver BRM?

Robust tool for central business rules management

Integrated path from process to rule

Perfect fit into SAP NetWeaver

Composition Environment

Eclipse based rule composition

Many Ways to Model Rules

Model Rules in the Context of a Business

Process using the Process Composer

Model rules as an independent rules project

using the Rules Composer

Many Ways to Integrate

Use Rules through an Automated Activity

Model Functions driven by Business Rules

Use rules based mapping transformations in

a process

Use rules based functions for Gateway

decisions

Typical Service Consumers

User Interfaces as Service Consumers:

Offering easy ways to call service functionalities

Creation of role, task, or process specific

user interfaces

Creation of reusable user interfaces for service calls

Services as Service Consumers:

Offering of web services that use other web services to provide functionality

Compound services combine functionalities of several services to one service

Tailor services to specific needs: Services offer tailored interfaces to provide

easier or special possibilities to call the original service functionality

Composite Applications as Service Consumers:

Using services within an application context

Calling services with process context specific information

Combining functionalities of different services to a complete application
