Key Metrics in Inventory Management:
1. Inventory Turnover: Inventory turnover measures the number of times inventory is sold or used within a specific period. It is calculated by dividing the cost of goods sold by the average inventory value. A higher inventory turnover indicates efficient inventory management.
2. Fill Rate: Fill rate measures the percentage of customer orders that can be fulfilled from available inventory. It indicates the ability to meet customer demand promptly. A higher fill rate signifies better inventory availability and customer satisfaction.
3. Stockout Rate: Stockout rate measures the percentage of customer orders that cannot be fulfilled due to inventory unavailability. A lower stockout rate indicates better inventory management and reduces the risk of lost sales and dissatisfied customers.
4. Holding Costs: Holding costs represent the expenses incurred in storing and maintaining inventory, including warehousing, insurance, and obsolescence costs. Monitoring holding costs helps identify opportunities for cost reduction and efficient inventory management.
5. Lead Time: Lead time measures the time taken from placing an order to receiving the inventory. Reducing lead time improves responsiveness, reduces the need for excessive safety stock, and enhances customer satisfaction.
6. Order Cycle Time: Order cycle time measures the time taken to process an order, from order placement to delivery. Reducing order cycle time improves efficiency, reduces costs, and enables faster order fulfillment.
7. Backorder Rate: Backorder rate measures the percentage of customer orders that cannot be fulfilled immediately and are placed on backorder. A lower backorder rate indicates better inventory availability and reduces the risk of lost sales.
8. Gross Margin Return on Investment (GMROI): GMROI measures the profitability of inventory investments by comparing the gross margin generated with the average inventory investment. A higher GMROI indicates efficient inventory management and higher profitability.
9. Days Sales of Inventory (DSI): DSI measures the number of days it takes to sell the average inventory. It is calculated by dividing the average inventory value by the cost of goods sold per day. A lower DSI indicates faster inventory turnover and efficient inventory management.
10. Perfect Order Rate: Perfect order rate measures the percentage of orders that are delivered to customers without any errors or issues. It includes metrics like on-time delivery, accurate order fulfillment, and complete documentation. A higher perfect order rate indicates better inventory management and customer satisfaction.
