Supply Chain Efficiency Metrics are data-driven measurements that help organizations monitor and evaluate how their supply chains are performing. These metrics measure the effectiveness of sourcing, receiving, transporting, stocking, and distributing materials and products in order to optimize performance and reduce costs. Some common efficiency metric categories include labor efficiency, inventory accuracy, on-time shipping, cost savings, and quality control. By closely tracking these metrics over time, businesses can identify areas for improvement and gain a more detailed understanding of the overall efficiency of their supply chain system.
