Providers of product-service solutions find it challenging to simultaneously manage an increasing need for customised offerings along with internal demands for efficiency. To manage this balance, this paper explores the utilisation of platform strategies in the development of integrated product-service solutions. While platform strategies have been employed for many years in the development of physical products, this paper focuses on platform strategies in the development of solutions that combine both products and services. Based on a case study, we identify different assets that can be shared by these integrated product-service solutions and provide rationales for using platform strategies for solutions. We emphasise the potential of applying platform strategies while acknowledging the need for a holistic perspective on what assets to share among solutions. In particular, we draw attention to knowledge platforms as a basis for development of product-service solutions. The potential from using technology and usage knowledge platforms is highlighted in particular.
