In current competitive market, efficient supply chain management is essential to achieving sustainable business success. This paper explores the integration of lean principles into supply chain operations and its impact on enhancing the value creation stream. Lean principles, originally developed in the manufacturing sector, focus on waste reduction, continuous improvement, and value maximization from the customer perspective. By applying these principles to supply chain management, organizations can streamline processes, reduce costs, and improve overall efficiency. The study investigates key lean methodologies, such as Just-In-Time inventory, Total Quality Management and the 5S system, and examines their application in various stages of the supply chain, including procurement, production, and distribution. Through a combination of case studies and empirical data, the research highlights how lean initiatives lead to significant improvements in supply chain performance metrics, such as lead time, inventory levels, and defect rates. Findings demonstrate that lean supply chain practices foster a culture of continuous improvement and collaboration among supply chain partners, ultimately enhancing the responsiveness and agility of the supply chain. Furthermore, the paper discusses the challenges and best practices for implementing lean principles in supply chain management, providing a roadmap for organizations seeking to optimize their supply chain value creation. The application of lean principles in supply chain management not only drives operational excellence but also contributes to greater customer satisfaction and competitive advantage. This paper underscores the strategic importance of lean thinking in creating a robust and value-driven supply chain.
