The present study is an exploratory research in terms of its purpose in terms of data collection. This research is also a mixed qualitative and quantitative research based on the inductive deductive philosophy. The statistical population of the study is experts who were selected using purposive sampling and based on the principle of theoretical adequacy.The data collection tool in the qualitative part is an interview, the validity and reliability of which was confirmed using content validity and theoretical validity and the method of intra-coder and inter-coder reliability.The data collection tool in the quantitative part is a questionnaire, the validity and reliability of which was confirmed using content validity and test-retest reliability.Qualitative data were analyzed using the content analysis method and quantitative data were analyzed using the fuzzy cognitive map method.The results of this study indicate that the lack of priority for managerial competence in the criteria for holding a position, the dominance of a culture of dwarfism, and the lack of a track for the effective presence of elites in the organization are the most important reasons for the emergence of the phenomenon of bench managers in government organizations.In addition, the migration of efficient and qualified managers to other organizations, the destruction and decline of the organization's talents, the creation of organizational inertia, and the reduction of knowledge and skill capital for the future of the organization were identified as the most important consequences of the phenomenon of bench managers in government organizations.
