Integrated service engineering (ISE) for service ecosystems

In all major industrialized countries, the service sector is the largest economic segment whose features have the highest growth rate. In this context, the Internet of Services has been developed with a focus on services which are offered and in some approaches even traded over the Internet. Services of various service providers are offered and executed via an electronic service platform which is part of a Service Ecosystem. Organisations can improve their business processes by outsourcing certain process activities to external partners and by integrating services into their IT-infrastructure through such service platforms. One impediment for Service Ecosystems is the development of tradable services. This paper introduces an interdisciplinary methodology for service engineering with a focus on business and technical aspects, and their integration. Additionally, this work elaborates on the business side and provides key questions to guide the engineering process. The methodology has been developed in the Theseus/TEXO project which is funded by the German Federal Ministry of Economy and Technology.
