Macy’s, Inc., through its subsidiaries, operates approximately 800 department stores in the United States. Its retail stores sell a range of merchandise, including adult and children’s apparel, accessories, cosmetics, home furnishings, and housewares. Senior management has decided that Macy’s needs to tailor merchandise more to local tastes, that the colors, sizes, brands, and styles of clothing and other merchandise should be based on the sales patterns in each individual Macy’s store. For example, stores in Texas might stock clothing in larger sizes and brighter colors than those in New York, or the Macy’s on Chicago’s State Street might include a greater variety of makeup shades to attract trendier shoppers. How could information systems help Macy’s management implement this new strategy? What pieces of data should these systems collect to help management make merchandising decisions that support this strategy?
