Digital transformation of modern educational environment is stipulated by recently occurred changes and intellectualization of information systems of various ecosystems. The aim of this study is development of methodology of design and implementation of digital technologies oriented at integral automation of department educational environment. Using the methods of system analysis, project management and simulation, the content and structure of digital component of this environment were analyzed, aiming at efficient formation of high-quality professional competences of graduates. The experimental results allow to substantiate composition of the required functional units. On the basis of the obtained data, the project concept of department educational environment is proposed, the activity of which is supported by integrated automation system of all information processes. Scientific novelty of the performed study is determined by that the existing automation system of educational environment in fact does not impact department level of information processes. On the basis of analysis of information processes of department level and existing technologies of their automation, a new methodological approach is proposed to conceptualization, development and implementation of fully functional digitalization system of department educational environment. The significance of the proposed approach is comprised of opportunity to integrate digital and content components of educational environment for improvement of education quality.
