Abstract

In today's world, where consumption is increasing rapidly, the designs of retail stores have gained importance with the increasing competition between institutions. One of the most predominant factors in the contact of the store with the customer is the spatial quality, which reveals the ability of the spatial features to meet user expectations. The study aims to determine the spatial quality indicators in retail stores and to expose the relationship between the importance and performance perception of these criteria among user groups. For this purpose, Importance-Performance Analysis (IPA), which has been a user-participated method and has powerful advantages in measuring service quality, was used in the study. In the first stage of the study, we determined the spatial quality indicators (functional, technical, and aesthetic) and sub-indicators by a literature review. The second stage is fieldwork performed in the determined study area, Koçtaş. At this stage, visual data of the study area was obtained, and 119 people (97 customers and 22 personnel) participated in the survey. In the third stage, IPA was used in analyzing the data. In the fourth stage, results were evaluated by supporting the visuals of the space. As a result of the study, the store was weak, especially in terms of aesthetic indicators, and significant differences were perceived by users between the importance and performance of spatial performance indicators. The study will lead up for research on examining the relationship between importance and performance in spaces with different functions by including the user in the process of determining and improving spatial quality.
