- Product-Service System (PSS) Design is new trend in new product and service design. In this paper, the E3 concept composed of economical, ecological, and experience values is proposed so that the PSS concept design and evaluation can be conducted with E3 values viewpoints. Economical values include cost reduction and income enhancement which can be achieved by differentiation, market creation, customer acquisition and retention. Ecological values address the issues such as energy and water saving, dematerialization, reducing hazardous materials, reuse and recycling. Experience values deal with more people-oriented viewpoints including utilitarian and hedonic aspects. With the adoption of consumer value framework by Holbrook, extrinsic and intrinsic value dimension is used as the first classifier of experience value and other aspects of experience such as emotional, social, and epistemic are also considered. In conceptual design phase, E3 values can be used by mapping onto lifecycle steps to identify various stakeholders’ requirements. Lifecycle steps and stages can be arranged with E3 value attributes in matrix form. By forced relationship analysis, stakeholders’ requirements can be identified in systematic manner. During the evaluation phase, E3 values can be used to compare PSS concept with its alternatives. Based on the concept of E3 value, alternative solutions can be compared with each other and relative importance or perceived preference can be assessed during the concept evaluation phase. We demonstrate how E3 values are used during design phase with the PSS case of a meal assembly kitchen: how to incorporate E3 values in the divergent and convergent activities of PSS design is described.
