Through-life Engineering in Product-service Systems - Tussles for Design and Implementation

While maintenance is still dominating in Through-life Engineering Services (TES), Product-Service Systems (PSS) emerge as holistic solutions for customer problems. However, there are still tussles to be overcome. Product and service engineering are using different methodologies and tools. Product design is still receiving little information from both life cycles, and a digital representation of PSS to ensure interoperability is missing. Professional design knowledge and customer sentiment have to be combined, while service-based business models could endanger product sales. This paper aims to discuss the challenges for PSS with TES and give an overview on attempts to overcome the identified tussles.
