Enhancement in Industrial PSS design based on TRIZ: a case study

Despite the emergence in literature of novel contributions in the Product-Service Systems (PSS) Engineering, there is still a lack of systematic knowledge in this area. Most of the proposed methodologies are mere adaptation of traditional engineering approaches to the PSS domain. In this context, one of the most analysed methods is the theory of inventive problem solving (TRIZ). Purpose of this paper is to propose a way to use the Laws of Technical Systems Evolution (LTSE) and the Evolution Trends to predict what are the most likely improvements that can be made to a given PSS. A case study makes evidence of the potential behind the adoption of the LTSE.
