The primary aim of this article is to graphically construct change management strategies within the system of enterprise sustainable development. The study focuses on the sustainable development system of an enterprise. The scientific task is the implementation of a new methodological approach to building strategies for managing changes in sustainable development system of enterprise. The research methods involve the use of technologies for constructing two variants of IDEF3 strategies. The IDEF3 method was utilized to capture descriptions of action sequences, enabling a specialist to construct change management strategies within the enterprise's sustainable development system. As a result, two unique examples of change management strategies in enterprise sustainable development system were presented. Consequently, we formed process-oriented and object-oriented strategies for managing changes in the machine-building enterprise's sustainable development system. These strategies allow for the inclusion of all elements of the enterprise's sustainable development in strategy formation. The implications of the study are the formation of a specific methodological approach to the presentation of the strategy for managing changes in the system of sustainable development of an enterprise. The study is limited as it only takes into account the specifics of the sustainable development system within an engineering enterprise. Prospects for further research should be devoted to the analysis of the change management system in the framework of security. The practical value of the results obtained lies in the possibility of using strategy models for top managers.
