[Type of Waste] Incorrect inventoryA product is not available to the customer, causing the customer to wait for it. [Examples] A customer places an online order for multiple items. At the time of the order, the customer is told that all the items are available and will be shipped at once. When the customer receives the order, not all the items are in the shipment, and some items are on backorder. “Murphy’s Law” would dictate that the items on backorder are the ones the customer most wanted. [Description]
