The TMS network A novel network of software environments and a Web service-based architecture • to support End-user Development activities 1 • to support end users to exploit their knowledge end expertise The TMS network allows end users to • design and check by visual composition • design and check by visual composition A workflow A workflow • visually validate the execution of • execute Workflow : a model to formalize a complex work process for further assessment and manipulation 2 1: Costabile F. et.

The TMS network The TMS network adresses two communities of end users Workflow designers Workflow operators Profile • Domain experts • Practitioners • Belong to an organization • Belong to the same organization • No IT experts of the Workflow Designer • No IT experts • No IT experts • Validate the workflow Role • Design the workflow • Execute it • Supervise its correct execution Tool • TMS editor • TMS instance Generalizzazione e conclusioni Introduction Methodology 4 Proposed architecture Interaction process Conclusions
