The thesis proposes an interdisciplinary framework for service research in information systems that goes beyond the technological concerns and integrates the business concerns about service processes and models and the user's concerns about service usage and value. Based on this framework, the thesis analyzes further the concept of service value and suggests the value perspective in the analysis and design of service systems. In addition, the thesis analyses the role of the user in service systems and suggests a method for service analysis and design that emphasises on the use of service by the user. The research outcomes can provide several research implications and insights and can inspire various potential uses, especially in research projects that seek to integrate a variety of technologies and services with the purpose to facilitate and enable people in their daily life practices.
