It is argued that a development of healthcare systems should emerge within a healthcare providing organization and as part of daily practice instead of something implemented by a third party, in order to become successful. This sociotechnical view on system development is shared with new methods developed in the end-user development field. However, is it possible to realize this in practice? This paper explores the obstacles and potentials in the realization, leading to a discussion about sociotechnical systems as innovation systems. We describe two examples of sociotechnical innovation systems, and discuss the results from an end user driven innovation process perspective.
