Which description best defines lead time in inventory management?

• A. The time taken to confirm the order before processing
• B. The time from supplier order to payment
• C. The time from production to finished goods
• D. The period from placing an order to receipt and stocking of goods

Answer: (D)

Lead time in inventory management is the period from when you place a purchase order to when the goods are received and ready to be stocked. This total span covers supplier processing, transit, and the receiving/put-away activities in your warehouse. Understanding this helps you set reorder points and determine safety stock because you must cover demand during that interval while the replenishment is in motion. If lead time is long or variable, you’ll need more safety stock to maintain service levels. The other descriptions describe internal processing time, the procurement cycle from order to payment, or production lead time, which are not the full replenishment lead time.
