An important point of the government as a platform is coordination with actors traditionally external for public administration (citizens, business) through shared software, data, and collaborative services. Unlike e-government, the focus in digital government is shifting to citizen participation: Digital government focuses on services, functions and governance through citizen involvement. The key point here is the interaction of man and technology: The implementation design is a set of principles, methods and norms of interaction between man and technology, that is, a techno-ecological system. The main thesis of the study is the following proposition: The institution of participation is the basis of the design of the "government as a platform" due to the deep foundations of Web 3.0 technology, which encourage participation and have a collaborative nature. Participatory governance is inherent in digital governance. In our study, we strive to demonstrate how the factors determining the classification of countries as developing affect the participatory governability, implemented through the government as a platform. In this study, we adhere to the Lean Government approach.
