Abstract: The article is devoted to the analysis of modern business process reengineering tools, such as SMART systems and artificial intelligence (AI), with a focus on their application in the Ukrainian IT sector. The advantages of these technologies are considered in the context of digitalization, globalization, and the challenges posed by the war with Russia. The necessity of a fundamental redesign of business processes to adapt to the dynamic changes of the external environment is substantiated, including new market conditions, changing consumer preferences, and a high level of uncertainty. Key aspects of the integration of SMART systems and AI have been identified, providing hybrid solutions to enhance productivity, adaptability, and enterprise competitiveness. The article emphasizes that digital technologies are critically important for efficient resource management, optimization of operational costs, and ensuring business resilience. The implementation of SMART systems allows for the automation of routine processes, increases data processing speed, and minimizes the human factor in decision-making. It is noted that the synergy of SMART technologies and AI contributes to the expansion of analytical capabilities, enabling enterprises to work with large data volumes in real time.

The integration of these technologies creates the foundation for building proactive business models focused on flexibility and scalability. Special attention is paid to analyzing the effectiveness of digital solutions in crisis situations, where rapid responses to external environmental changes are crucial. The article also notes that the use of AI in IT companies allows for the development of personalized products and services, increasing customer satisfaction levels. It is emphasized that the effectiveness of digital solution implementation largely depends on the culture of innovation within companies and their readiness for change. The article further discusses the necessity of close collaboration between businesses, scientific institutions, and government bodies to develop comprehensive solutions in the field of business process reengineering. It is determined that the use of big data analytics in combination with AI enables the prediction of risks and the creation of development strategies based on evidence-based data. The importance of ethical aspects in AI applications is highlighted, particularly regarding algorithm transparency and accountability for decision-making.The impact of digital technologies on the labor market is also examined, stressing the need for personnel retraining to effectively work with new tools. The potential for integrating smart solutions to enhance supply chain and logistics efficiency in the IT sector is analyzed. The article concludes that expanding the capabilities of digital technologies allows Ukrainian IT companies to successfully compete in the global market, ensuring high-quality services and products.
