An evaluation method for designing a new product-service system

Although the importance of the design of a new PSS (Product-Service System) should be emphasized, it is not obvious that traditional evaluation methods of pure services are still appropriate for PSSs. Since methods to evaluate the feasibility of new businesses vary with the characteristics of businesses, the evaluation methods might need to be modified to reflect unique nature in the design of a new PSS. Therefore, this paper aims at improving the applicability of evaluation methods for designing a new PSS by proposing a new framework and performing an empirical study where a new evaluation method can be used for PSSs. To this end, first, the meanings of service innovation, PSS, and evaluation methods in service research will be investigated. Second, an evaluation method for designing a new PSS will be suggested by considering the perspectives of service providers as well as customers. Finally, the method will be applied to evaluate the feasibility of designing a car-sharing service that is a use-oriented PSS. This method will provide a good means of drawing a potentially successful PSS by applying the proposed evaluation methodology and process.
