Relational sociology provides a foundational lens for understanding how social realities are constituted by networks of relationships rather than by isolated actors. Within this relational paradigm, scholars introduced the concept of relational learning to explain how organizations learn through interaction with partners. Relational learning has been conceptualized as an organizational capability that spans firm boundaries, enabling companies to create value with and through their network of stakeholders. Rather than learning in isolation, companies engage with others, exchanging information, interpreting insights together, and applying knowledge in a coordinated manner. Relational learning ties in the broader sociological view that considers relationships as formative contexts for learning and meaning creation. This construct can “synthesize both the meso and micro perspectives,” clarifying how companies learn and innovate when guided by shared goals. The evolution from relational sociology to relational learning reflects a growing recognition that enduring relationships between companies and their social context are central to how organizations acquire new knowledge and capabilities. In the following sections, we examine relational learning as an organizational capability, its key dimensions, and how it differs from the related concept of absorptive capacity. We conclude with some reflections on how relational learning can be incorporated into supply chain management practices and performance.
