Previous research has investigated transitions of individual firms to PSS business. It has identified barriers and enablers and specified organizational capabilities needed. However, the transition to PSS has seldom been approached from a product-chain perspective. In addition, previous research has indicated the need for more assessments of environmental gains related to PSSs. This study aims at contributing to these perceived knowledge gaps by means of a case study. Questions posed include: Does the study's case company and one of its suppliers have the capabilities needed to adopt a PSS business model? and Could a PSS really contribute to material efficiency in their product-chain?
