Methodological aspects of digital platform management

Digital platforms are the largest data aggregators and beneficiaries in the digital economy. Digital platforms operate at micro, meso, macro and mega levels in various formats and in almost all areas of human activi-ty. Platform companies have a number of unique competitive advantages compared to traditional com-panies and require specific methods, models and management tools. The research objective is to deter-mine the features of the functioning of digital platforms and develop methodological foundations for the formation of models for managing digital platforms. The theoretical and methodological basis of the study are the works of domestic and foreign scientists on the problems of managing digital platforms and digital transformation. Results. In the course of the research, the classification of digital platforms was generalized and systematized, based on the analysis of domestic and foreign experience in 10 classification criteria. Organizations and meta-organizations can have multiple types of boundaries, so there are ad-vantages to developing a holistic view that can reveal complementarity and interaction between them. Not-ing that there is an interaction between different types of boundaries, the boundaries of a digital platform can be defined as a combination of the scope, configuration, and digital interface of the platform. In addi-tion, it should be noted that due to the specifics of digital platforms, we consider it appropriate to single out the digital environment along with the external and internal, some of the digital environment factors can be attributed to the external environment, and some to the internal, while the boundaries of the digital envi-ronment are open. Analysis of the element-by-element model of the digital platform made it possible to highlight its distinctive features. The core value of a platform company is not a classic physical unit of val-ue, but an infrastructure that enables interaction between producers and consumers. Conclusion. Thus, key interaction design is the core of every digital platform. Key interaction is the reason why participants use digital platforms. The anatomy of a key interaction consists of four characteristics: value creation, connec-tion, consumption, compensation. Various participants can be categorized as platform core, platform par-ticipants, and platform environment.
