What does lead time demand refer to?

• A. The amount of inventory needed to cover demand during lead time.
• B. Demand forecast for the upcoming quarter.
• C. The rate of production during lead time.
• D. The total annual demand.

Answer: (A)

Lead time demand is the amount of inventory you need on hand to meet customer demand during the replenishment lead time—the period from placing an order to receiving it. It represents the expected demand that will occur while you’re waiting for new stock, and it’s typically estimated by multiplying the average demand rate by the lead time. This concept is essential for deciding how much to stock now and for setting reorder points and safety stock to avoid stockouts while not tying up unnecessary inventory. The other ideas describe demand or capacity outside that specific lead-time window: forecasting quarterly demand covers a broader horizon, production rate during lead time is about how much you can manufacture in that period, and total annual demand spans a full year.
