Lead time in manufacturing is the total span from when an order is placed to when the finished product is delivered to the customer. It encompasses order processing, procurement of materials, actual production, packaging, and shipping. This full interval best matches the idea of the time from order placement to delivery, because it includes every step that happens between initiating the order and receiving the product.

Setting up production lines is only one part of the cycle—setup time—so it doesn’t capture the entire duration. The time between shipments focuses on gaps between shipments rather than the end-to-end process from order to delivery. The time to place an order with suppliers covers just the initial trigger and omits what happens afterward, so it’s not the complete lead time.
