Testing the Methodology to Generate Design for Product Service Supportability (DfPSS) Guidelines and Rules: An Application Case

The industrial world is today navigating from a traditional product-based business to a new more complex solution-based orientation, pushed by new technologies, a multiple functionalities demand and a change in the customer value perception. Several are the methods and tools proposed in literature to aid manufacturers to design those solutions in an integrated and systematized way but none of them is really able to consider together product and service components, according to both company and customer views. In this context, a methodology generating new Design for X (DfX) guidelines to support the early integration of service features already in the product design of PSS has been proposed by the authors. This methodology can raise engineers’ consciousness in designing PSSs in a systematic and integrated way and provides insights into the link between the design process of PSS and the design knowledge generation in terms of guidelines and rules. In particular, the objective of this paper is to test this methodology through an application case. The test, following a theory building procedure, contributes to obtain the final methodology design, providing a double result: industrial experts’ feedbacks, giving to the authors a major awareness of its strengths and weaknesses, and new industry-specific PSS design guidelines and rules.
