Abstract—In the current competitive landscape, innovation is key to achieving business success. With the constraints of internal resources, businesses are increasingly turning to external collaborations to enhance innovation, especially with their suppliers. This trend has led to the emergence of Supplier-Driven Innovation (SDI), a strategy enabling businesses to supplement their innovation efforts with knowledge and capabilities from suppliers. Despite its significance, there is a notable gap in the literature regarding a theoretical foundation for SDI. This study aims to address this gap by proposing a conceptual framework that advances the understanding of buyer-supplier innovation literature in three key areas: outlining SDI processes from the buyer’s perspective, clarifying suppliers’ roles in these processes, and exploring the contribution of each identified process to the innovation outcomes. This framework can serve as a guide for practitioners navigating through the complexities of SDI, facilitating its integration into business strategies and enhancing competitiveness in the market landscape.
