6. Motivating Business Scenario –Simple, but Realistic What kind of apples do you have? We provide 5 alternatives: ..... What is the price of the 2nd and 4th option? The 2nd is x$ and the 4th is y$ I take 5 pieces of the second option Fine.

7. Principles of the Solution • Separation of business logic and implementation technologyModel-driven approach • Based on UN/CEFACT´s Modeling Methodology (UMM) • Business process centric • UMM is business process centric • Business state centric • Adjust UMM to a business state centric methodology • Business context sensitive • Exetend UMM to develop multi-context models • UMM is a Model-driven approach • UMM models inter-organziational processes • UMM considers business entity states • UPCC considers context

9. UMM – the Meta Facts Graphical process modeling technique for inter-organizational (B2B) business processes Concentrates on business semantics – is implementation neutral Provides a procedure similar to a software development process from requirements elicitation to process design UMM is defined as a UML profile on top of UML 2.1.1

10. The UMM Terminology Business Process Group of related activities that together create customer value Traditionally intra-organizational, but also inter-organizational Business Collaboration Performed by two business partners (=binary collaboration) ormore business partners (=multi-party collaboration) Complex, composed of many activities (=business transactions) between the partners Business Transaction Always a binary collaboration Realized by a request from one side and an optional response from the other side (information exchange)

12. Business Domain View - Example Use case diagram Business process activity model refining the use case above

13. Business Partner View Purpose Container for business partners and stakeholders that are identified in the business domain view Modeling organization relationships between those actors (optional) Actors represent Business Partner and Stakeholders

14. Business Entity View Purpose Identification of relevant business entities a business entity is something that has real-world significance (e.g., order, newspaper,...) Describing the lifecycle of business entities A business entity state that is shared between two business partners is a strong indicator for a required exchange of business information

22. Conclusion and Outlook UMM provides a holistic methodology for defining global B2B scenarios UMM is defined as a UML Profile and can be used with any UML modeling tool of choice A UMM model can be used to derive deployment artifacts for a SOA e.g. BPEL or WSDL artifacts For more information, example models, tools and academic work on UMM please visit http://www.umm-dev.org
