Which statement correctly describes lead time?

• A. The time from starting production to shipping.
• B. The time to pay for goods after receipt.
• C. The total time from when a customer places an order to when they receive the product, including processing, production, and delivery.
• D. The time goods spend in inventory before being ordered.

Answer: (C)

Lead time is the total duration from when a customer places an order to when they receive the product, including every step in between—order processing, production or assembly, and final delivery. This full end-to-end span is why the statement describing all those stages best captures lead time. The other ideas refer to narrower pieces of the process or separate activities: one describes only the production-to-shipping portion (production lead time), another focuses on when payment occurs (financing terms), and another looks at how long items sit in inventory before an order is placed (inventory holding time). In practice, understanding the complete order-to-delivery timeline helps with planning, customer expectations, and responsiveness.
