The contemporary digital economy necessitates a reevaluation of business process management, making the task of their comprehensive digital transformation a pressing priority. Conventional approaches frequently prove to be inflexible, hindering companies' ability to adapt to swiftly evolving circumstances. This paper explores the theoretical and practical aspects of developing frameworks and techniques for enhancing business process management, considering the obstacles posed by digitalization.

The purpose of the research is to develop and implement effective models and methods for optimizing business process management aimed at increasing their productivity, adaptability and sustainability in the digital economy. The research solves the following tasks: analyzing and systematizing existing theoretical approaches to managing business processes in a digital environment;  testing optimization models adapted to the use of digital tools such as artificial intelligence, big data, cloud technologies and robotic process automation (RPA).

The theoretical importance of this study is the creation of a scientific framework for the digitalization of business operations, the creation of classifications based on the level of digital maturity, and the development of strategies for digital transformation. The practical value of this research is the potential for applying the developed models and techniques across a wide range of industries to enhance efficiency, reduce expenses, and improve process control.

The research approach is grounded in the comprehensive application of theoretical and methodological frameworks, drawing upon scientific literature, comparative analysis, and structural-functional examination of both traditional and digital models. The study employs digital analytical instruments, including Python, Power BI, and Bizagi, and conducts practical testing of models within the context of small and medium-sized enterprises. The findings can be applied in the context of digital transformation to foster sustainable growth and enhance organizational competitiveness.
