Platforms have gained significant attention in the field of information systems (IS) research. However, the concept of platforms remains fluid and complex due to the diverse phenomena associated with it. Research to date tends to cluster around two predominant perspectives: the economic network perspective and the architectural design perspective. To reconcile the divergent perspectives of platforms and establish a more cohesive foundation for IS theorizing, we undertake an interpretive literature review through the lens of service-dominant (S-D) logic. Drawing on an extensive analysis of the literature, we develop an S-D Platform Framework that provides a deep understanding of the multifaceted nature of platforms as a vital IS capability for value co-creation. This framework sheds light on the fundamental facets of relationality, ambidexterity, and cooperativity, which explain the deep structure of platforms in the realm of IS research. Building on our proposed framework, we put forth an agenda that aims to guide future studies towards a more theoretically compelling trajectory.
