- In Product-Service Systems development, understanding of the customers' use of goods seems vital, since the product per se is not sold but rather the performance it brings to the customers' processes in terms of added value. This changed business scenario insists on an integration of a service and a product perspectives in early design phases. However, the approaches to understand customers diverge. In this paper, a need matrix, from the economic theory of needs, and a requirement matrix, from the TRIZ methodology, are used to elaborate on integration aspects to understand customer statements. The comparison of these matrixes made the distinct logics apparent, and gave an indication for the necessity of another type of specification for PSS products. Also, the knowledge base for PSS methodologies has to be extended to encompass a part that visualizes non measurable aspects such as needs.

- In order to codify, manage, and reuse the knowledge gained from pursing product development projects, CAD-programs have started to provide functionality for supporting this activity. Since the primary purpose of the CAD program is to interactively define geometry, the functionality has been integrated primarily to be used on the parameters of the CAD-model of the design instance. This paper explores how the functionality can be used in a broader scope, managing and automatically reusing knowledge for all designs intended for a certain production process. This is facilitated by automatically converting an arbitrary CAD-model of a design to a format that is accessible for knowledge handling and reuse functionality in the CAD-system. A conversion algorithm for the processes die-casting and powder metallurgy pressing sintering is presented, as well as showing how the knowledge can be represented in the CAD-system. This will allow engineers to actively participate in the knowledge build-up and insure that the general knowledge can be handled in the companies’ IT-infrastructure.
