Services are the vital part of a service-oriented architecture. Their development and design are essential parts of the development and implementation of a service-oriented architecture. Thus, numerous approaches in research and practice exist that refer to different aspects of service design. These are focused on specific needs or aspects in service design. According to the literature review provided in this paper, no single service design approach covers all the aspects that are needed for the implementation and deployment of a service-oriented architecture. Beside the literature review this paper provides a service design approach that combines the existing methods and approaches. The goal is its further development towards a service design method for service design in research and industry.
