Abstract [en]

As a result of the deregulation of the Swedish railway market, the differentfunctions involved during the life cycle of railway products have been spreadout over different actors. The trigger for the work presented in this thesis wasthe insight that, since function-specific knowledge of the railway in Swedenbelongs to different organizations, special efforts would be needed to achieve aholistic picture of a railway product during the conceptual design phase. However,there is a lack of methods developed for groups with participants fromdifferent organizations possessing different functional knowledge about a product.The overall aim of the research for this thesis was therefore to develop anideation method and a concept selection method specifically for groups actingin the context of the Swedish deregulated railway market, with members fromdifferent organizations with different functional knowledge. By means of actiondesign research, the methods were developed within the scope of a researchproject involving four different actors on the Swedish railway market.The project group tested Method 635, the gallery method and the SIL method.Overall, the gallery method was most popular and the SIL method leastpopular among the participants. Method 635 was found to have a considerablyhigher idea and concept generation rate than the gallery and SIL methods.The developed ideation method combines the rotational viewing of generatedideas in the group and gallery viewing with steps of verbal interaction wherethe group members take turns to present and comment on generated ideas. Theproject group regarded the developed method as the best method of all themethods which they had tried, and it outperformed the other methods with regardto the total number of generated concepts and ideas. The views of the projectgroup on the method correlated positively to the views of participants takingpart in field tests of the method.The developed concept selection method combines refined versions of theprocedures for topic clarification, goal specification, requirement specificationand concept screening developed by Pahl and Beitz with a concept scoring procedurebased on the life cycle and societal costs associated with each conceptthat fulfils the stated requirements.The most important effect of the composition of the group was found to bethe wide range of viewpoints on the topic at hand that the representative groupof different relevant actors was able to provide.

2. Ideation methods applied in a cross-functional inter-organizational group: an exploratory case study from the railway sector

Abstract [en]

The conceptual design phase is a critical step, since it influences the subsequent steps during product development with regard to cost, quality and performance. Previous research has focused on cross-functional teams within an organization. However, many product development projects benefit from the participation of members from different organizations, not least during the conceptual design phase of technical products, where it is essential to consider different aspects of the product-to-be. Therefore, we conducted an in-depth case study of a cross-functional inter-organizational group testing ideation methods in a real-life setting within a development project in the railway sector. The group comprised participants from an infrastructure manager, a supplier, a maintenance contractor and research bodies. The tested ideation methods were Method 635, the gallery method and the SIL method. The participants found working in a cross-functional inter-organizational group to be beneficial both during the group-analysis of the topics and during the generation of ideas on how to address the ideation topic. Applying the ideation methods to the ideation topics facilitated the sharing of information between participants, and the diversity of the group manifested itself in several ways during ideation. Overall, the gallery method was most popular, and the SIL method was least popular among the participants.

Abstract [en]

A great number of ideation methods are available to assist the engineer in the conceptual phase of product development. Previous research on idea generation suggests that, in order to understand how ideation can be successful in reality, the context must be taken into account. Therefore, evaluating promising ideation methods in the intended use setting should be an important complement to other research studies in the field of engineering design. In the present study, an ideation method which had previously been developed by the present authors in close collaboration with industry, a government agency, and academia was evaluated in a typical use setting. Testing the method in a use setting led to unexpected events and to new insights into the method. During the most ideation-intensive stage of the method, one of the groups in the use setting generated suggestions at a rate similar to that of the small representative group in which the development of the method had taken place, whereas the other three groups in the use setting had a lower suggestion generation rate. The findings indicated that the participants' views on the method correlated with those of the group which had developed the method.

Abstract [en]

During conceptual design, concept generation and selection methods can be used to facilitate the generation of new ideas and the selection of the most promising suggestions. The present paper is an effort to understand better how action design research can be utilized to develop such methods. Using action design research, methods were developed through iterative cycles of building, testing and evaluation in the context of a deregulated railway market, through a close collaboration between actors from industry, a government agency and academia. The approach was found to be feasible and to provide generalization of the context-specific findings through the formulation of design principles.
