The thesis is devoted to the improvement of theoretical principles and substantiation of proposals for the development of a comprehensive methodology for evaluating the effectiveness of the internal control system to provide recommendations for improving the accuracy of evaluating the effectiveness of the internal control system in the Ministry of Defense of Ukraine.
The scientific novelty of the obtained results:
for the first time: the comprehensive methodology for evaluating the effectiveness of the internal control system of the Ministry of Defense of Ukraine has been developed, which contains three interrelated stages:
‒ identification, formulation and scientific substantiation of the system of indicators of efficiency of functioning of SIC;
‒ selection of key indicators of the effectiveness of the SIC, their evaluation;
‒ formation of a matrix of key indicators and determination of the generalized indicator of efficiency of functioning of SIC.
Consistent implementation of these stages of the complex methodology makes it possible to determine the level of functioning of the SIC of the Ministry of Defense of Ukraine institution by calculating the corresponding generalized numerical indicator, which according to the proposed evaluation criterion will indicate the level of functioning of the SIC in the institution;
there were improved: the existing system of indicators of efficiency of the internal control system, which, unlike the existing ones, combines qualitative and quantitative scientifically substantiated indicators taking into account the specifics of the activity of the institution of the Ministry of Defense of Ukraine.
The study formulates and substantiates a system of 93 quantitative and qualitative indicators that cover all five elements of the SIC, namely: internal environment, risk management, control measures, information and communication (information and communication exchange), monitoring.
further development was given to the use of the KPI (Key Performance Indicators) system in assessing the effectiveness of the internal control system of the Ministry of Defense of Ukraine. To date, the system of KPIs in assessing the effectiveness of JCA has not been used not only in the Ministry of Defense of Ukraine system, but also in other industries. The KPI matrix used in the study made it possible to calculate a generalized indicator of the efficiency of the SIC, which combines key indicators that may indicate the effectiveness of the SIC.
Practical value of the received results lies in the possibility of introducing a comprehensive methodology for assessing the effectiveness of SIC in the audit activities of the internal audit unit not only in the Ministry of Defense and the Armed Forces of Ukraine, but also in other internal audit units of central executive bodies of Ukraine.
The results of the dissertation can be used by higher education institutions in the training of specialists in internal audit and internal control, managers of all levels of government, who directly organize the functioning of internal control and internal audit in subordinate structural units (units).
Key words: state internal financial control, internal control system, internal audit, risk management, efficiency assessment.
