Abstract: The article explores the options for implementing digital transformation tools in the operational management of business organizations to overcome the problems that arose as a result of a full-scale military invasion of Ukraine: market instability, reduction of markets due to the temporary occupation of the territory of Ukraine, a decrease in the number of customers and suppliers since a significant part of the population of Ukraine migrated abroad; the reduction of financial resources of business organizations, the existence of high prices for certain IT products and the low level of digital skills among employees.
