Co-creating integrated solutions with customers requires collaboration of different partners within a value network. In this emerging context, knowledge is considered as a foundation for value co-creation. Therefore, identifying different types of issues, with which value network actors in knowledge transfer are confronted, is conceived as a first step toward, on the one hand, the prevention of the failure of knowledge exchange initiatives in a network, and on the other hand, the enhancement of the collaborative process of knowledge sharing. This requires shifting the conventional approach on knowledge transfer issues from an intra-organizational to an inter-organizational network. This paper aims to systematically identify and classify knowledge transfer issues with both tacit and explicit knowledge considerations. In doing so, we have first conducted a systematic literature review to identify issues. Secondly, these issues have been classified into six main categories and 29 subcategories through a structured classification approach. The proposed classification framework provides a comprehensive and wide spectrum of possible issues related to knowledge transfer within a value network. It also presents a step towards an improved awareness of such issues in order to resolve problems in transferring knowledge in such contexts.
