Shows interconnected metrics across inventory, fulfillment, and costs
Supply chain efficiency depends on multiple interconnected metrics. Inventory turnover measures how quickly inventory converts to sales - higher is generally better but varies by industry. Perfect order rate combines on-time delivery, order accuracy, and quality into a single end-to-end metric. Supply chain cost ratio shows logistics expenses as a percentage of revenue. Cash-to-cash cycle time measures working capital efficiency from payment to suppliers through customer collection.
