Retailer processes centred on the food market as the main determinate of business models in the context of retail size

In today's competitive environment, retail food outlets need to keep pace with changing consumer behaviour and technological change. Due to the impact of digitalisation, they are gradually starting to use new forms of interaction with consumers, suppliers, employees and other stakeholders, which affects the food retail business in many ways. Many digitization-related activities are well known but are slow to be implemented in the practice of food retail operations, depending on the specific size type of retail format. The paper aims to provide an overview of business models based on the size of food retail operations and on the identification of selected activities aimed at increasing competitiveness and creating value for customers. The survey sample comprised 250 stores whose managers were questioned by means of a semi-structured interview in March–April 2022. The authors discuss 30 identified components of 40 purposes in this study which could increase the efficiency of retailers' business models. A number of philosophical (a comprehensive examination of the criteria for selecting a theory and processing the theory) as well as mathematical statistical methods are used in the model, such as reliability rate estimation, factor analysis of binary data, cluster analysis, and the like. The study provides an overview of the application of selected digitalisation-related components in the business models of established food retail outlets of different size groups in the Slovak capital Bratislava.
