Companies are looking for new approaches and tools to help them meet their customer's demands, particularly the desire of customized products at lower costs. The paradigm of product-service systems brings companies the opportunity of enlarging their offer, looking at products and services in an integrated way. This paper presents the early prototype of a software platform that supports companies in designing PSSs using feedback information collected over the value chain. The prototype described has been tested in three industrial companies and is currently being further developed.
