Product-Service Systems (PSS) were proposed by the United Nations Environment Program (UNEP) in the late 1990s. Publications on the subject began to emerge after the release of the report "Product Service systems, Ecological and Economic Basics" [1], which was written to stimulate discussion on the subject, being commissioned by the Dutch Ministries of Environment and Economic Affairs. PSS is offered as an integrated package of products and services [2,3] with the aim to deliver an outcome, functionality, or a system's availability [4]. While providing solutions that can meet the needs of end customers, PSS contributes to reducing resource consumption and environmental impact [5]. Therefore, PSS may help to manage the sustainability of organizations [6], by providing a 'triple-win' wrapping economic, environmental, and social requirements [7]. One example of PSS is Riversimple that offers hydrogen-powered cars that customers can rent by paying a monthly fee to covers car use, maintenance, insurance, and fuel [8]. Bike-sharing systems such as the French Velib', and the growing start-up Yellow are another example of PSS, offering bicycle rent for a limit amount of time. In business-to-business (B2B) market, examples are numerous [9]. More recently and influenced by the digitaliza-Product-Service Systems (PSS) appears as an emergent subject, gaining the attention of many researchers, and an increasing interest of organizations. As many literature reviews have been conducted in PSS-related field, this paper aims to overview publications from 2006 to 2018 by highlighting PSS benefits and barriers. Content analysis was used to codify data collected in the publications. The main characteristics of the literature reviews are provided as well as a set of 36 PSS benefits and 24 barriers organized in categories and sub-categories. Analyzing PSS-related review papers allows identifying future research opportunities which can foster the design and implementation of PSS business models.
