1. Introduction
The interest in strategic use of MIS in the health care sector both as a research topic and in practical information system development has led to an increased understanding of how MIS gets caught up in heterogeneous processes of change [19]. This implies that neither the strategy process nor the enabling role of IT can be understood without investigating how a MIS becomes enabling within a certain context [17]. IT development can fruitfully be viewed as a continuous process of change within a mixture of deliberate strategies and emergent strategies [15]. Moreover, strategic use of IT must face the challenge of legitimacy. The health care sector is characterized by several and partly contradictory logics, values and interests all of which have a legitimate status. For instance, administrative control must compete and potentially be in conflict with claims for professional autonomy. It is well known that deliberate strategies face resistance from stakeholders whose interests are perfectly legitimate.
