Introduction. The current conditions of industrial operations are characterized by the need to enhance sustainable economic performance of enterprises amid digital transformation and increasing competition. The integration of lean manufacturing tools and digital technologies is becoming increasingly relevant due to its potential for generating synergistic effects. Goal. The study aims to conduct a systematic analysis of the impact of lean manufacturing tools and digital technologies on the key economic performance indicators of industrial enterprises and to identify the effects of their integration. Materials and methods. The methodological basis of the study includes works by Russian and international scholars. The research applies methods of systems and comparative analysis, as well as a practical approach based on data from case studies, analytical reports, and applied industrial research. Results and discussion. It has been established that lean manufacturing tools such as standardization, 5S, VSM, SMED, and visualization have a targeted impact on key production and resource metrics, including labor productivity, capital productivity, material efficiency, cost, and profitability. Digital technologies (IoT, Big Data, AI, and digital twins) enhance these effects by enabling process automation, real-time decision-making, and system adaptability. The integration of these approaches allows the formation of digital lean manufacturing as a new management paradigm. Conclusion. The combined implementation of lean manufacturing and digitalization ensures sustainable growth in economic performance and fosters the development of adaptive production systems capable of thriving in the digital economy.
