The technology department at any manufacturing enterprise is engaged in ensuring the release of new high-quality products on time with high economic efficiency. Depending on how successfully the technical department functions, the quality of technical documentation and, as a result, the quality of products depends. In this regard, it is necessary to constantly improve the efficiency of this department through the introduction of new management solutions, including those based on the use of modern software. This article discusses the process of introducing a product data management system into the technology department of a high-tech enterprise. A modified reengineering algorithm for the technical department is presented, functional modeling of business processes in the IDEF0 rotation is considered, and functional models are built. A small economic evaluation of the results of the implementation of the PDM system in the technology department is also carried out, and the results are presented. It is shown that the greatest effect of using a product data management system lies in two areas: reducing time to market and improving product quality. Thus, the introduction of the proposed system can significantly improve the quality of the production process not only in the department in question but throughout the enterprise.
