Final answer:
A senior level supply chain manager can be evaluated using metrics such as the inventory turnover ratio and the on-time delivery rate.
Step-by-step explanation:
A metric that could be used to evaluate the performance of a senior level supply chain manager is the inventory turnover ratio.
This ratio measures how quickly a company is able to sell and replace its inventory. A higher inventory turnover ratio indicates that a supply chain manager is effectively managing inventory and minimizing the holding costs associated with excess inventory.
Another metric could be the on-time delivery rate, which measures the percentage of orders that are delivered on schedule. A high on-time delivery rate indicates that the supply chain manager is successfully coordinating all aspects of the supply chain, including transportation, logistics, and delivery.
