Starting from the 90s, an increasing number of companies have been starting to move from a product-centric perspective towards Product-Service-System (PSS). In this context, suitable models, methods and tools to collect, engineer and embed in a single solution all the knowledge that meets or exceeds people’s emotional needs and expectations are required. Despite that, only few authors have proposed methodologies that can be easily adopted by industrial companies to design and engineer a product-service solution starting from the customer needs. Thus, this paper focuses on the customer needs analysis and aims at proposing a methodology to support companies in identifying customer needs, representing the starting point to the engineering and/or reengineering of PSS offering and the related delivery processes. An industrial case study in ABB S.p.A. has been carried out in order to test the methodology.
