Category management is the management of product categories, and product categories are products that customers consider related. The goal is to identify the criteria that define products within a particular category. Optimal product placement meets customers' desires and needs, giving the product maximum value. With product categories, a strategy for procuring and managing products is determined when placing them in the stores. The category management process entails defining the category, breaking it down into segments, and assessing the role of the category. Goals are aligned, and strategies for displaying goods of particular importance on the shelves are determined, followed by implementation. Space management is the management of space. It is part of category management because it defines the optimal placement of products in the store by organizing product category databases. The best physical utilization of space with the aim of productivity and profitability is achieved with space management. Space management aims to enhance the appeal and comfort of the retail space for customers, prompting them to select items and to prolong their stay in the store. Using scents, colors, lighting, music, aesthetics, and shelf layout creates a pleasant atmosphere, impacting customers' senses and shaping their shopping experience. Product placement by category is determined by a planogram to increase sales. Lidl, Takko, and DM are excellent examples of product management. Upon entry, shelf layout and product placement are immediately visible, demonstrating the implementation of category and space management, which allows companies to gain customer loyalty.
