A framework for managing and utilizing product–service system design knowledge

This study focuses on how to manage and utilise design knowledge in the conceptual design of product–service systems (PSSs). PSS is a business concept that manufacturing firms can use to enhance the value of their products. In order to design an effective PSS, it is important to search for value proposition opportunities throughout the entire product life cycle and offer appropriate services to customers at each opportunity. Because both products and services are included in the design space, PSS designers need to use a broader range of knowledge than that required in product design. Against such background, this article proposes a framework for managing and utilising PSS design knowledge to support idea generation in PSS design. The effectiveness of the framework is demonstrated by its application on an example of PSS design.
