As a result of the deregulation of the Swedish railway market, the different functions involved during the life cycle of railway products have been spread out over different actors. The trigger for the work presented in this thesis was the insight that, since function-specific knowledge of the railway in Sweden belongs to different organizations, special efforts would be needed to achieve a holistic picture of a railway product during the conceptual design phase. However, there is a lack of methods developed for groups with participants from different organizations possessing different functional knowledge about a product. The overall aim of the research for this thesis was therefore to develop an ideation method and a concept selection method specifically for groups acting in the context of the Swedish deregulated railway market, with members from different organizations with different functional knowledge. By means of action design research, the methods were developed within the scope of a research project involving four different actors on the Swedish railway market.
