14. Supply Chain Operations Reference (SCOR) modeling looks to measure, manage, and improve supply chain performance for your company. When your company's inventory levels have inefficient variances, inventory spoils, or customers become frustrated by not being served adequately. Then the "bullwhip effect" can take place, meaning the frustrated customers will then make it even harder for your company to minimize inventory variances. Suppose your company has Location A and Location B. The annual standard deviation in the inventory levels at Location A is 30,000 items. The annual standard deviation at Location B is 20,000 items. It's your job to test the theory that Location A's variance is significantly higher than Location B... leading to possibly closing Location A. Utilize the F-test (also known as ANOVA) to see if Location A has a significant problem compared to Location B
