Knowledge integration with customers in collaborative product development projects

Purpose This paper addresses the need for managerial and organizational approaches to knowledge integration with customers in collaborative product development projects. The purpose is to identify the roles of customers in terms of the customer's knowledge contribution and timing of customer collaboration in the product development process. Design/methodology/approach This study is based on a multi-case study approach, comprising four product development projects from two large international suppliers. The cases were selected following the theoretical replication logic. Data consist of interviews, workshops, and secondary information. For each of the cases, a within case analysis was performed followed by a cross-case analysis. Findings The study shows that the customer's knowledge contribution is aligned with the specific requirements of each phase of the product development. Three specific customer roles are identified and connected to the customer's knowledge contribution and the timing of customer collaboration. The technical capability of the customer and the locus of initiative of the product development project are affecting the prerequisites for knowledge integration with customers. The study is performed from the perspective of supplier firms. The authors have not been able to capture the perspective of the customer in detail. As it is expected that both customers and suppliers benefit from a systematic knowledge exchange, future studies could examine knowledge contributions in both directions. Practical implications The findings can be used to devise effective approaches for collaborative product development with customers related to the customer's knowledge contribution and the timing of customer collaboration and provide guidance to firms seeking to benefit from knowledge residing at customers. Originality/value This is one of the first studies to focus on the integration of customers' knowledge in product development processes. This paper contributes to the customer–supplier collaboration literature by presenting further insight into customers' knowledge contributions, the timing of customer collaboration in product development processes and the prerequisites for knowledge integration with customers.
