The context and problem of identifying and thereafter representing, analyzing and managing information and knowledge about an organization has always been very crucial to achieve business goals in an efficient and flexible way. Particularly in a PLM context, the issue of information overload is growing in importance. An emergent challenge consists in providing a context-driven access to federated information and knowledge and fostering cross-discipline collaborations between actors to improve quality in product development. This paper highlights key issues for knowledge definition and representation. We propose a bottom-up approach based on the User Story Mapping method (USM). This method is user-centric and leads to the definition of current and/or expected scenarios and processes along with a collaboratively agreed vision. Common concepts and viewpoints are therefore derived and generalized through a process of merging defined roles, activities and usages sequences with a focus on the product content. This bottom-up approach provides a federated and common understanding of information throughout the industrial product and process lifecycle; which combined with appropriate tools and methods, such as questionnaires, standards specifications, knowledge based approaches, etc. results in the definition of the knowledge network and domain and therefore improves capabilities for sharing and reusing this knowledge in collaborative product development. The proposed approach is applied in the context of the FP7 European project LinkedDesign (Linked Knowledge in Manufacturing, Engineering and Design for Next-Generation Production) based on three application scenarios.
