Most modern integrative processes related to the automation of production facilities do not bring the expected increase in efficiency. This paper is devoted to the complex use of modern integration technologies during the combination of management systems of production facility process and an enterprise as a whole. It is obvious that during the organization of this kind of work, various difficulties arise, the main of which are discussed in this paper and the recommendations for their solution are given. The solution proposed in the paper is beneficial in terms of relatively low implementation costs, the possibility of rapid implementation and relative simplicity. The main attention is paid to the issues of project management at the initial stage, when the influence of conceptual differences in the choice of the method of technical implementation is maximally strong. The use of the proposed methods can significantly improve the quality of system integration projects. The method proposed in this paper can increase the efficiency of the implementation and use of IT projects at large industrial enterprises.
