The object of the study is the activity of an agribusiness enterprise in using digital technologies. The problem of the methodology for assessing the effectiveness of using digital technologies by an agribusiness enterprise is solved. The following results were obtained: – the author's methodology for assessing the effectiveness using of digital technologies by an enterprise of AIC based on expert evaluation and a system of indicators was developed. The assessment results are interpreted in accordance with the matrix of intersection of the digitalization index and the effect of digital technologies from Outsider (0–0.25; <1) to Leader (0.95–1; ≥1); – the obtained concordance coefficient (76 %, χ2=41.9) indicates high consistency of the expert group, consistency and qualitative assessment in the process of testing the methodology; – testing of the proposed methodology in Atameken-Agro JSC was successful and showed the validity and convenience of this methodology. The agro-enterprise became the leader in 2023 with the indicators of digitalization level – 0.83 and the effect of using digital technologies – 12.5. The above results are explained by assuming the possibility of using the expert judgment method to evaluate the efficiency of using digital technologies by an enterprise and applying a decision matrix based on two indices. A particular feature of the results obtained is the development of a methodology for assessing the level of digitalization in three main areas and its application in combination with the assessment of the economic effect of digital technologies. The proposed methodology can be used not only by enterprises wishing to evaluate the effectiveness of digital technologies but also by stakeholders.
