Especially the early phase of the innovation process, the planning phase, is characterized by extensive decisions and a wide range of uncertainty. Hence, it is essential for product designers to understand future Product-Service System characteristics and prospective properties. Thus, in this paper we present a framework for depicting a Product-Service System model throughout the planning phase of the innovation process based on existing methodologies in product and service modeling The user of the framework should be supported in decision making and keeping the overview during the early phases of product development so crucial decisions can be made on a conceptual and reasonable basis.
