ABSTRACT
This chapter discusses how Business Process Modeling and Business Process Modeling and Notation 2.0 can capture business requirements and provide the backbone of the actual solution implementation. This is achieved via a new process-centric architecture that preserves simplicity and stability in the business-oriented enterprise process description layer while maximizing flexibility and agility in the underlying service contract implementation layer and vice-a-versa. The process-centric application layer never interacts directly with the underlying system landscape; instead, it always goes through the service contract implementation layer. Model-driven development proposes to improve the state of the art in software engineering. The Model-Driven Architecture guide discusses a wide variety of transformation types, techniques, and patterns. Unified Modeling Language helps firms to specify, visualize, and document models of software systems, including their structure and design. SAP Business Rules Management applications are by nature process-centric and exist to support and enrich end-to-end business processes, incorporating both manual and automatic tasks, and they can extend beyond enterprise borders.
