The modern business landscape is characterized by unprecedented globalization, technological innovation, and increasing complexity in supply chain operations. Organizations are compelled to adopt strategic vendor development practices, advanced sourcing strategies, and digital transformation initiatives to maintain competitive advantage, reduce operational costs, and enhance overall efficiency. This research investigates the integration of vendor development, supplier monitoring, inventory optimization, and digital supply chain strategies as mechanisms to achieve cost efficiency and sustainable performance. By synthesizing insights from empirical studies, systematic reviews, and theoretical frameworks, this study emphasizes the significance of triadic supply networks, strategic partnerships, and digital capabilities in achieving operational resilience. The paper highlights the interplay between labor management, globalization effects, and the triple-A (agility, adaptability, alignment) supply chain framework, illustrating how firms can enhance responsiveness and maintain competitiveness in complex global markets. The research also explores the challenges of governance, resource allocation, and knowledge management within supplier networks, offering practical insights for procurement managers and supply chain professionals. Ultimately, this study contributes a comprehensive theoretical and practical framework for organizations aiming to leverage vendor development and sourcing strategies for optimized supply chain performance in an era of digital disruption.
