To What Extent Does the Layout of a Departmental Store Affect Consumer Decision Fatigue?

A departmental store layout and product placement shape the consumer decision-making process. This paper begins by charting the psychological flow of decision making and identifying the critical points that lead to decision fatigue, a cognitive stage where repeated or complex choices exhaust mental resources and lead to suboptimal decisions. This paper further aims to provide a nuanced understanding of how the retail environment of a department store influences consumer behaviour and cognitive load. Three types of store layouts are analysed: free form, grid and racetrack. A free-form layout allows the consumer to explore products and integrates various departments together for higher sales; this configuration causes comparatively high levels of decision fatigue among consumers as it encourages browsing and they are left to navigate products by themselves. A grid layout eases the navigation process by arranging aisles in a parallel structure. However, retailers can achieve the best shopping experience with low levels of decision fatigue among shoppers by implementing a racetrack layout, which not only reduces the need for consumers to decide their path but also reduces cognitive overload by guiding the consumer along one main aisle.
