2. (Irrespective of your answer in question 1) Suppose the total value of 2010 inventory is $11 million and the increase in value of inventory required by Scientific Glass is $1.6 million. Gregory and Hayes suggest four policy changes to reduce the value of the average inventory (page 7 in the case). For each suggested change below, estimate the savings that can be expected if the change is successfully implemented and discuss if the estimated savings can compensate for the increase in inventory of $1.6 million. a. It is estimated that for 10% of all products, Scientific Glass maintains an overly high service level. Assume this overly high service level is 99.9% (z-value = 3.09) and suppose the company decides to enforce a strict 99% (z- value = 2.33) service level for all products. i. Using data from the case and Exhibit 3, complete the table below.
