A method for analysing conceptual design process of product-service systems

One of the major features of product-service systems (PSS) design is a variety of design elements. This makes its design process complex and obscure. This study aims to develop a method for analysing how the design process influences the features of design solutions in the conceptual design of PSS. In this study, protocol analysis is applied to plural PSS design sessions. Simultaneously, their design solutions are evaluated relatively based on several aspects. Their design processes are analysed in connection with the above evaluation results. The findings obtained by using the proposed method will contribute to creating practical design guidelines for superior PSS development.
