Which metric is used as a performance measure of supply chain delivery reliability of an industrial chemical manufacturer?

This metric measures the time taken between outlaying cash for raw material and receiving cash from product sales. While important for understanding cash flow and operational efficiency, it does not specifically assess delivery reliability or performance in the context of order fulfillment.

Inventory turnover indicates how often inventory is sold and replaced over a period. Although it provides insights into inventory management and sales efficiency, it does not directly measure the reliability of the supply chain in terms of fulfilling customer orders accurately and on time.

Order fulfillment lead time measures the time taken from receiving an order to delivering it to the customer. While it is related to delivery performance, it does not encapsulate all aspects of reliability such as accuracy in order and completeness of delivery, which are critical components of perfect order fulfillment.
