Purpose: The purpose of the current study was to identify, quantify, and prioritize the components of reducing the resistance of managers of government organizations in the administrative transformation plan. Methodology: The mixed study method is based on exploratory mixed study. The statistical population in the qualitative section was university professors, managers, and experts of executive systems, in the quantitative section, managers and experts of government agencies, and in the prioritization section, high and middle managers of executive systems of selected organizations. In-depth interviews were used in the qualitative part, while questionnaires were used in the quantitative part, and matrix questionnaires were used in the prioritization one. Acceptability (expert review) and confirmability (expert review) were used to determine the validity and reliability in the qualitative stage, while in the quantitative stage, the validity of the questionnaires was confirmed by three methods: form, content, and structure. Reliability was estimated and confirmed by three methods of determining factor loadings of items, Cronbach's alpha of components (between 0.760 and 0.888) and combined reliability (between 0.842 and 0.923). In the prioritization section, the content of the matrix questionnaire was approved by five academic and organizational experts in terms of comprehensibility and expressiveness, and the rate of inconsistency of the criteria was calculated and confirmed as 0.05 to 0.07. Qualitative data were analyzed with the ground theory technique, while quantitative data with structural equation modeling technique, exploratory and confirmatory factor analysis tests in SPSS and Smart PLS software, and the prioritization section, data were analyzed through hierarchical analysis (AHP) in EXPERT CHOICE software. Findings: The results of the qualitative part indicated that the paradigm model includes 10 dimensions (categories) and 22 components (concepts) in the form of causal, contextual, interventional, strategy, and consequence conditions. Conclusion: The results of the quantitative part showed that all the components of the study model were confirmed. The results of the prioritization section show the greater importance of the outcome and organizational productivity component.
