This chapter explores the intersection of Product-Service Systems (PSS), Service Design (SD), and Service-Dominant logic (S-D logic) in driving sustainable servitization. It provides a literature-based foundation for understanding how these frameworks collectively enable systemic transformation towards sustainability. While S-D logic emphasizes value co-creation and relational exchange, service design focuses on human-centred innovation and experience-driven interactions. PSS, in contrast, facilitates sustainability through product-service integration and circular business models. The chapter applies Galbraith’s Star Model™ to illustrate how these perspectives reshape organizational structures, processes, and strategies to embed sustainability. It further examines tensions between product- and service-dominant thinking, highlighting how companies can overcome barriers by adopting a holistic service-oriented mindset. Using an industry case study, we demonstrate the practical implications of integrating these frameworks to transition from product-centricity to sustainable business models. Ultimately, this chapter provides insights for businesses seeking to enhance competitive advantage while aligning with principles of environmental stewardship, social equity, and economic resilience.
