| Abstract | Reduced product lifespan results in accelerated flow of materials and ultimately more waste. Rapid technology cycles, frequently changing consumer preferences and increasing market competition, provide consumers with an opportunity to use products with more functions and better quality at a cheaper price. Consequently, these products quickly become technologically, psychologically, or economically obsolete even before the actual end of their physical life/economic value-resulting in shorter product life cycles. These products are often disposed as landfill. In this context, it can be argued that reduced product lifespan has a significant impact toward, both the environment and the economy. To address this issue, our study investigates the concept of upgradability while exploring its potential as a product lifetime extension strategy. Several research papers regarding product upgradability have been published in the past in a variety of settings/domains. However, the collective contributions of these papers have yet to be summarized in order to provide a platform of knowledge for furthering the research on upgradability. To contribute to the body of knowledge, this article aims to identify, interpret, and summarize the current literature available on product upgradability. First results indicate growing interest and promising potential of upgradability as a product lifetime extension strategy, especially given the increasing importance of a product's middle of life phase in the context of Product-Service Systems (PSS). Additionally, upgradability facilitates the implementation of the circular economy, the dissemination of PSS, as well as remanufacturing approaches. However, our findings show that research on upgradable PSS is still dominated by theoretical work and more empirical research is necessary to further establish this concept. In terms of future work, there is a clear need to develop upgradeable PSS-specific design methodologies as well as associated sustainable business models. (C) 2018 Elsevier Ltd.
