The ubiquitous digitalization and introduction of digital technology have, in recent years, radically changed the way retail businesses work. Integrating different technologies into customer interactions has changed practices, processes, and activities in various ways. While some become merely digitally enhanced, other activities have been replaced by completely digital practices. Based on information from scientific literature, web-content analysis as well as experts’ knowledge, an iterative taxonomy building algorithm results in a comprehensive and meaningful classification of these digital practices, able to classify any practice of interest in the field of customer-centric retail practices. The use is to further understand them and, in turn, derive better benefits from them.
