A Holistic Methodology for Model-Driven B2B Integration: From Business Values over Business Collaborations to Deployment Artifacts

Business-to-business (B2B) electronic commerce based on the principles of Electronic Data Interchange (EDI) systems has been conducted for a long time. In recent years, we observe a switch to a rather business process-based thinking for implementing inter-organizational systems. UN/CEFACT's Modeling Methodology (UMM) - which I co-authored - is considered as one of the mature graphical modeling approaches for modeling inter\-organizational business processes. However, UMM has still several shortcoming that prevent a throughout model-driven software engineering approach. In this PhD proposal, further contributions to the UMM are identified that are required to lift it to an holistic B2B methodology for the development of inter-organizational systems. These contributions will extend the UMM to become an integrated approach starting with business models, leading over to business collaboration models, and finally resulting in deployable artifacts for business service interfaces. The proposed top-down approach is in line with the ideas of model-driven engineering resulting in shorter development cycles and reduced complexity.
