Information technology has since the turn of the millennia been one of the core issues in the reform of public administration in government agencies. Aiding this development has in some countries and in the research community been discussed through the development of stage models describing the evolution of services in stages. This is the case in Sweden where the Swedish agency for administrative development has been using a model to describe, evaluate and promote the emerging services. This paper pivots on the discussion about the conceptual foundation for models such as the Swedish model and other models. The discussion is conceptually founded in information systems actability theory and IS usage situations. This paper addresses the issue of stage models and the concept of stages itself. The models discussed lack in the categorization of the described stages; borders between stages are undistinguishable and unclear. A refined model that addresses the discovered issues is presented in the paper.
