It focuses on reducing waste, improving efficiency, and increasing value delivery within the supply chain network. Key principles of Lean Supply Chain Management include minimizing inventory, shortening lead times, improving production and distribution processes, and enhancing collaboration and communication among supply chain partners. The goal is to create a more responsive and cost-effective supply chain that meets customer demands while minimizing resources and operating costs.
