A Study on the Effectiveness of Supplier Quality Management Strategies in Global Supply Chain Networks

This study examines the effectiveness of Supplier Quality Management (SQM) strategies in global supply chain networks, focusing on how integrated quality frameworks, technological innovations, and collaborative supplier relationships enhance performance and competitiveness. SQM represents a structured approach to ensuring supplier compliance with quality standards, reducing operational risks, and promoting consistency across complex, multi-tiered supply chains. The research draws on key theories such as Total Quality Management (TQM), Supply Chain Quality Management (SCQM), and systems integration models to explain how firms achieve superior quality outcomes through collaboration and continuous improvement. It highlights the growing influence of international standards like ISO 9001:2015, IATF 16949, and Quality at Source (Q@S) in fostering transparency, accountability, and efficiency among global suppliers. Moreover, technological tools—including Artificial Intelligence (AI), Internet of Things (IoT), automation, and Enterprise Resource Planning (ERP) systems—have revolutionized supplier evaluation and quality monitoring by providing real-time data visibility and predictive analytics capabilities. The findings emphasize that effective supplier selection, development, and risk management strategies are critical in ensuring sustainability, regulatory compliance, and resilience against disruptions such as counterfeits and supply bottlenecks. Case studies of global firms further demonstrate that successful SQM depends on continuous collaboration, digital integration, and adherence to global quality standards. Overall, the study concludes that organizations that strategically align technology, quality standards, and supplier collaboration are better positioned to sustain long-term performance, innovation, and competitive advantage in an increasingly interconnected and volatile global supply environment.
