The document discusses the evolution of value propositions in the context of technology commercialization, highlighting the transition from goods-dominant logic (GDL) to service-dominant logic (SDL) in value creation. Through case studies of four firms, it demonstrates how value propositions are iterated based on dialogue with customers to address unique situational needs. The findings suggest that both GDL and SDL approaches have their place depending on market conditions, and emphasizes the importance of co-creating solutions with customers.
