The evaluation of a Product-Service System (PSS), particularly during its design phase but also throughout its lifecycle, is a challenging problem. It exhibits dynamic nature and is multidimensional, since a large network of stakeholders are usually involved in the design and development of PSS eco-systems and their influence must be considered during the evaluation of the PSS offering. Nevertheless, an effective PSS evaluation can determine the market success of the PSS offering, leading to fewer design modifications and shortened time-to-market. Still, existing literature lacks an exhaustive review and classification of PSS evaluation approaches. Moreover, a lack of critical in-depth validation of performance approaches in real industrial environments is observed. Towards bridging this gap, the present work identifies the most important perspectives in the PSS ecosystem, such as supplier selection and service level, and discusses the utilised evaluation approaches used for each of them. Based on this review, a classification of existing PSS evaluation approaches is provided, by mapping these PSS eco-system perspectives to the methods most frequently used for their evaluation. The results can be used as guidelines for PSS vendors to select the most suitable method for the evaluation of their PSS offerings.
