The evolution of service-oriented architectures towards digital ecosystems comprehends a number of challenges. According to Papazoglou et al., one challenge is to develop services in a dynamic environment with high uncertainties, and in collaboration with other companies. The Integrated Service Engineering (ISE) Workbench is a step in this direction in that it supports a modeldriven approach and different stakeholders. This paper briefly introduces the ISE Framework, presents the ISE Workbench and its functionality, and proposes a demonstration of a conducted case study in the IT outsourcing domain.
