Abstract:
With the shift to a service-oriented architecture, goals concerning the IT of an organization, such as an increased flexibility and maintainability, are expected to be attained. For this purpose, the building blocks of the service-oriented architecture, the services, have to be designed that certain quality attributes, such as loose coupling or autonomy, are fulfilled. Existing design processes for services name these quality attributes and consider them as important. However, they do not explain their usage within a design process in order to create services that verifiably fulfill these quality attributes. This article shows an enhancement of existing design processes that on the one hand comprehensibly describes how to derive service designs from artifacts of the business analysis and on the other hand integrates quality attributes in order to enable a verifiably quality-oriented design of services. The approach is applied to design services for a system at the Karlsruhe Institute of Technology that guides students across the campus of the university.
