  3. 2 ways • Target Architecture development is top-down • Baseline bottom-up

  4. Business Modeling • Activity Models • Use-Case Models • Class Models • Node Connectivity Diagram • Information Exchange Matrix

  5. Activity Diagrams • Activity diagrams are graphical representations of workflows of stepwise activities and actions with support for choice, iteration and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e. workflows).Activity diagrams show the overall flow of control.

  11. Use-case models

  12. Class Diagrams

  13. Node connectivity

  14. IER • The Information Exchange Requirements (IER's) identify who exchanges what information with whom, why the information is necessary, and in what manner.

  15. E.g: RosettaNet — www.rosettanet.org

  16. Tmforum
