In this chapter, an introduction to service-dominant (S-D) logic is provided and used as a platform to explain how firms can use this logic to develop strategies that provide them competitive advantage. A brief review of the foundational premises of S-D logic and the expanded view of resources upon which S-D logic is grounded is provided. This is used to discuss how firms can develop strategies centered on developing value propositions that offer service flows rather than tangible goods. This strategy is enhanced by an understanding of the service ecosystem the firm operates within and how to sense and respond in this system. Finally the importance of conversation and dialogue with other members of the service ecosystem is discussed.
