Category Management tries to obtain the best of products in retail, by organizing and displaying them at the right way on the store shelves. It also aims to find the best marketing strategies to each category, as if it were a business strategy unit. This tool has been used in partnership between manufacturers and big retail nets, where these goods are sold to the final consumer. The purpose of this paper is to describe the methodology of Category Management, to report what are the basic conditions necessary to put it into practice and, through the study of a particular case, to analyze whether the small retail examined could use this tool in its stores.
