In product development, one critical source of knowledge is experience made in the manufacturing phase of a products lifecycle. Hence, the collaborative interaction between design and manufacturing is explored. Results from a descriptive case study of practices for reuse of manufacturingknowledge are compared with data from a previous study. Together they provide a comparison between three different business areas (automotive, aerospace and defense). The studies reveal similar problems in utilizing the full potential of knowledgereuse. This paper contributes to the research area by describing current practices within knowledgereuse. Furthermore, proposals for improved practices of knowledgereuse are identified.
