Empirical Studies on Product-Service Systems - A Systematic Literature Review

The aim of this paper is to increase the understanding of empirical PSS research, and provide insights for future directions in PSS research. Based on an in-depth systematic literature review of 70 journal articles, it was found that PSS practices have been widely applied across various geographical and research areas. The majority of empirical research employed qualitative research method while large scale quantitative studies are still scarce. In addition, a large portion of product-oriented PSS studies demonstrate that PSS is still in its early development stage in terms of evolution. With regard to research themes, PSS design related studies are the focus of more than 40% studies.
