On the background of an emerging shift from a product, goods-dominant to a service-dominant logic (SDL) in business and society, there is a need for further theoretical grounding of information systems development (ISD) in general and for agile development in particular. This paper presents SDL and the concept of service ecosystem as a promising complementary theoretical basis for broadening the understanding of agile development. Based on an analysis of in-depth interviews with experienced agile practitioners and their current involvement in large agile projects related to managing such projects, we investigate the question how agile development can be understood as a service ecosystem, and how such a perspective impacts more general on the scholarly understanding and practice of information systems development.
