This document provides an introduction and methodology for a thesis project that aims to empower Product-Service System (PSS) designers. PSS combines products and services to deliver functionality in a more sustainable way. The project seeks to address challenges PSS designers face in their studies and careers in applying these skills. It does so through participatory research with PSS designers at Politecnico di Milano to understand their needs and identify opportunities. The goal is to answer how these designers can be empowered along their pre-professional and professional journeys to create new opportunities.
