The study of domestic and foreign developments in the field of management of economic systems, management based on system, process and functional approaches allowed us to identify, form and describe the attributes of management practice. At the same time, materials on the structuring, classification and use of management activities from various points of view were used. Based on these generalizations, the interaction of attributes of the management practice of processes and objects in social and economic environments was established. The structure and content of the practice section of management ontology are presented and its relationship with other sections of management science is shown. This research is valuable for research, educational, social and educational activities of processes and objects of economic systems of various types and forms of ownership.
