Abstract :
Abstract — Product-service system (PSS) is a system of
products, service, supporting networks and infrastructure
that is designed to be competitive. The concept of PSS is
rather new and currently many companies and governmental
institute are eager to implement the PSSs as a new business
model. In this paper, we propose a three-dimensional model
to classify PSS based on three axes. The three axes consist of
selling product type, product usage type, and sustainability.
The selling product type is classified as physical product,
physical product and added services, and product-service
system. The product usages type is classified as productoriented,
use-oriented, and result-oriented usage. The
sustainability is classified as economy, society and
environment. The 3D model is applied to the surveyed
Korean industrial practices to identify some typical
migration paths from physical product to PSS. Three typical
migration paths are identified and the paths are used to
suggest Sustainable PSS(SPSS) development strategies.
Three identified paths are value-extended SPSS, positioningextended
SPSS, and field-extended SPSS.
