It is hypothesized that the use of outsourced processsing is an effective adaptive solution to overcome the personnel shortage in the war in Ukraine, which will enable business entities to optimize costs, ensure continuity and flexibility of activity, and attract highly qualified specialists. The research was carried out using the methods of analysis, comparison, systematization, empirical studies and case studies, as well as horizon scanning and logical modeling. The challenges of outsourced processing in the conditions of war are analyzed, examples of its successful application in conditions of personnel shortage are provided. The conducted studies form scientifically based approaches to determining the directions of integration of outsourced processing in the activities of business entities.
