50 pagesInternational audienceProduct development processes comprise highly creative and knowledge-intensive tasks that involve extensive information exchange and communication among geographically distributed teams. Due to the geographical and institutional separation between the different systems involved in the product lifecycle, retrieving, sharing and exchanging product knowledge is becoming a key issue in information systems of extended enterprise. This paper addresses the issue and challenges of product knowledge traceability during the product development. The aim of this research effort is to enhance the exchange and use of product knowledge acquired during the development process. In order to satisfy the needs for acquisition and reuse of product knowledge, a product knowledge representation framework is proposed. Key elements to support traceability during product development process are identified. The key idea behind this research effort is based on the premises that an important step towards achieving product knowledge sharing is providing traceability across various product knowledge elements that are used in product development phases, i.e. design and manufacturing. Two complementary case studies illustrating the benefit of traceability are presented. The potential role of traceability is described, first to support the decision making process during engineering change management, and second to support product oriented modelling for knowledge sharing and exchanging to meet quality requirements

The global crisis and the fierce competition of emerging countries make companies struggling to stay ahead of competition. The number of companies that are enlarging their offer portfolio looking forward to new and increased sources of revenues is always increasing but the number of companies failing in successfully implementing servitization strategy is even more. One possible reason behind this is the lack of tools to support companies while dealing with services that by definition are characterized by high level of intangibility and perishability. The Service Engineering (SE) discipline that is currently working for an integrated development of tools and methodologies specifically related to services is still under development and the existing methodologies are more oriented to the manufacturing context. In the SE context Pezzotta et al., in 2014 suggested the SErvice Engineering Methodology (SEEM) for the engineering and the re-engineering of new service or Product-Service System (PSS) helping the companies in balancing their internal performance with the service value perceived by the customer. This paper aims at understanding the industrial applicability of such methodology. It presents a real case study carried out in collaboration with ABB Spa, a leading provider in power and automation technology. In the paper, all the steps performed during the application of the SEEM are described, together with the difficulties encountered. Some insights obtained with the application are also described.
