You work for Stardust and you managed a improvement project to reduce the waste of milk in one of Stardusts stores. Milk is delivered in bottles of 1 gallon and employees fill each coffee using these bottles and store them back in the refrigerator. Each coffee is suppose to have on average 1 ounce of milk, but this store was consuming about 1.5 ounces of milk per coffee sold. Your team went through all Define, Measure and Analyze phases and came up with the following improvement ideas. Which one should you do first?
