After a product has been produced and has been put into the inventory, it can be packaged and delivered to the customer. Depending on the specific manufacturing environment, a product may not even sit in a physical inventory location at all, and instead may be shipped almost immediately to the customer. Meanwhile, in another industry, you may have a product that is produced and then sits in a warehouse for months before delivery. Of course, it is always possible that something gets produced and gets left in dead stock. In this case, you would never have a delivery order and instead use a process to determine how to manage that dead inventory.
