Sustainable Product-Service-Systems: the Kathalys method

Developing Sustainable Product Service Systems (SPSS) is an unavoidable but at the same time a challenging opportunity for companies. The article describes an approach for developing SPSS based on experiences of Kathalys. The Kathalys method is a five step phased approach with guidelines for future exploration to implementing new sustainable products and services. Developing SPSS is an opportunity for companies because it results in new visions of the future and innovation opportunities that fit into this future. At the same time it stimulates the formation of coalitions with (new) partners and the development of new sustainable businesses. The Kathalys method can guide companies through the different stages of these developments.
