INTERACTIVE MODELING AND EVALUATION OF PRODUCT-SERVICE-SYSTEMS

Product-Service-Systems (PSS) are an opportunity for differentiation within the globalized producing industries. The design of PSS concepts challenge companies and question their generic business model. As a result, companies have to cope with complex activities 'opportunity recognition', 'PSS design' and 'business planning' without the support of an integrated approach that is easily understood and applicable by all collaborating stakeholders with a minimum of training. The objective is the development of a modeling procedure for PSS which supports a systematic variation of its typical properties and allows interdisciplinary interaction in teams. The paper presents a business model canvas, a PSS-life-cycle and PSS-configurator imbedded in a procedural model. The methods as well as the procedure are evalueted by 3 case studies with industrial partners. Furthermore, the case studies investigate the influence of the derived methods on the product/service-ratio of the provided solutions of the industrial partners within the case studies. Finally, the paper gives an outllook on the enabled strategic evolution of a company's generic business model to a business model of a PSS provider.
