Purpose - The purpose of this essay is to explore further the concept of value cocreation from a service-ecosystems view, by considering the importance of networks and the configuration of relationships and resources in markets. Methodology/approach - We use a conceptual approach to extend a service-dominant (S-D) logic, ecosystems view of value cocreation by drawing on the literature regarding networks in marketing and related research. Findings - A service-ecosystems approach to cocreating value-in-context is proposed, which points toward networks as mediating factors in value cocreation because they influence the ability to access, adapt, and integrate resources by establishing exchange relationships and shaping the social contexts through which value is experienced. Research implications - This research suggests that value cocreation is a complex and multidimensional process that is best studied in the context of dynamic networks or ecosystems of service exchange. Practical implications - This research suggests that networks mediate value cocreation, and thus, firms should consider the configurations of relationships and resources to develop more compelling value propositions. Social implications - This research draws on the idea that exchange relationships are embedded within society and suggests that processes of value cocreation not only draw on but also contribute to the social contexts that frame market exchange. Originality/value of essay - This research extends the value cocreation and S-D logic literature by exploring the role of networks in service ecosystems. In this framework, networks are mediators of value cocreation because they enable access to resources and help to (re)shape social contexts through which value is derived.
