Identifying new PSS concepts: The product-service concept tree

This chapter provides a short introduction to the Product-Service System Lean Design Methodology (PSSLDM). "Company" and "customer" are the core elements of the PSSLDM, highlighting the main objective of the methodology, namely the trade-off between customer satisfaction and company performance. To this purpose, the PSSLDM encompasses the following four phases: customer analysis, solution concept design, solution final design, and offering analysis. Among the different methods developed within the methodology a specific one, called the Product-Service Concept Tree (PSCT), has been created with the aim of supporting the translation of customer needs into marketable solutions. The chapter explains the two main sub-phases of the PSCT method and tool: solution(s) concept generation and solution(s) concept selection. The ambition of the PSCT is to support companies in identifying PSS concepts valuable for the customer and profitable for the company.
