Abstract
Due to societal/environmental crises caused by excessive pursuit of productivity and efficiency in the last decades, the social awareness recently tends to respects sustainability and the role of design to achieve social well-being and equality. To address this, Product-service systems (PSS) is regarded as a one of the promising way to contribute to sustainable society. PSS is a system that is highly integrated by tangible products and intangible services to fulfill a particular customer demand and environmental benefit. On the other hand, to take advantage of PSS benefit for sustainability, it is essential to appropriately design and diffuse to be accepted by socio-technological system (STS) in which PSS is implemented. Moreover, STS has a property of transforming dynamically under the influence of internal and external disturbances caused by environmental, social and economic changes. Therefore, it is difficult to develop a PSS by traditional approach that regarding system statically. The purpose of this study is to construct a PSS development method that is accepted by socio-technical system with a systematic approach considering the characteristics of dynamic and multi-scale systems. To this end, this paper proposes a conceptual framework enables co-design of sustainable product-service systems by conducting related literature review. As a result, this paper identified five system levels to take into account and their relationships and five development processes for developing PSS to diffuse in STS.
