You have been working as an operations assistant at ABC Company, which assembles and sells coffee makers. Your target market is North America, and you distribute your finished products in 15 models (8 colors for each model) through five large retailers in Canada and the U.S. You buy over 125 parts in different colors from 28 suppliers in Canada, China, U.S., India, and Vietnam. Because of having too many models and colors, you spend a lot of time on machinery setup and buying numerous parts in small quantities. Sometimes you run out of parts, so you import them by airplane.
