Three factors are primarily used in conventional retail shop layout design approaches: product categories, cross-elasticity, and consumption universes.

Product categories: Based on the implications of the industry, this layout mostly shows manufactured products. Supermarkets arrange similar products together to make it easier for customers to choose them. Supermarkets, for instance, commonly arrange products into sections for the bakery (for instance, grouping items like bread, cakes, and biscuits), the vegetable section (for instance, beans, cabbages), and the fruit section (e.g., apples and oranges), consumers are accustomed to locating products on the same shelf or in the same aisle. 

Cross-elasticity: This design stresses how changing prices in one product can affect sales of that product it also captures how pricing can be used to capture cross-product interactions in demand. Product categories are arranged side by side in accordance with cognitively logical pairs, which are referred to as cross-elasticities. The use relationship between categories is therefore captured. With this design, customers can quickly compare products’ advantages and disadvantages during a single store visit.

Consumption universes: This is a “data mining approach using a consumer-oriented retail layout strategy”. This arrangement presents breakfast items including tea, bread, cheese, and cereal all in one location. Instead of looking for tea in the beverage department, fresh cheese in the cheese section, and cereal in the cereal section, use this strategy. Other universe kinds include the dinnerware world and the infant universe, which can be grouped into various product categories. It can be quite appealing to busy consumers to group products based on consumer purchasing patterns. Customers may feel satisfied in these scenarios since the retailer seems to comprehend their requirements and personal situations, which in turn may influence consumer purchase decisions favorably.
