Supplier management is a strategic and systematic approach encompassing the processes and interactions organizations undertake with their external providers of goods, services, or resources, involving the selection, evaluation, and optimization of the supply base. As a research concept and field of study, it investigates the dynamics of these relationships, the effectiveness of strategies for supplier engagement, performance measurement frameworks, risk management techniques, and the impact of supplier interactions on overall supply chain and organizational performance. Key characteristics include a focus on building collaborative relationships, integrating suppliers into internal processes, pursuing value creation beyond cost reduction, and mitigating supply chain risks. Its significance lies in its critical contribution to cost efficiency, quality assurance, innovation, supply chain resilience, and ultimately, competitive advantage and long-term organizational sustainability.
