The main objective in designing product layouts is to enhance product visibility and accessibility. This involves organizing products in a way that is logical and appealing to customers, which helps to maximize sales and minimize the time and effort required for production. In comparison, the goal of scientific management, which is closely related to product layout design, was to increase workers' efficiency by optimizing work processes and reducing waste.
