Acceptability, transferability and verifiability were used to determine reliability and the coefficient (86.20%) was obtained and the reliability of the interviews was confirmed. Micmac software was also used to draw the structural-interpretive model. After analyzing the interviews, 37 indicators were obtained in the form of 5 concepts in the field of weaknesses and 17 indicators in the form of 3 concepts in the field of strengths. The result of interpretative-structural modeling showed that the highest level of influence was related to the weak component of the management system and the highest level of influence was related to the weakness of sports economy. Considering the high impact of the weakness of the management system on other components, it is suggested that meritocracy along with effective supervision be implemented in the management structure.
