The research aims to test the relationship and impact of complexity management and its dimensions as an independent variable in strategic performance and its dimensions as a responsive variable, through dynamic capabilities and its dimensions as an intermediate variable, in some private colleges, and based on the importance of the subject of research, the researcher depended the descriptive analytical approach in the completion of his research which dealt with a Random sample class number (143) individuals, representing the sample of research, represented by the senior leaders of the research faculties, depended the questionnaire as a main tool in the collection of data, and used a set of appropriate statistical methods for research to test the hypothesis, the most prominent results of the research were to prove the validity of the main hypothesis embodied the impact of complexity management directly and indirectly by strategic performance, and the impact is high in the case of the intermediate dimensions of dynamic capabilities, and the dynamic capabilities contribute to reducing the levels of complexity management and strategic performance in the private colleges, and the most prominent recommendations were the need for the research faculties to pay attention to the variables of research, especially the complexity management and strategic performance of the effects they cause through the renewal and diversification of activities and tasks carried out by colleges and the elimination of routine activities in the work by investing in the opportunities available to them). As well as identifying what search variables are Its and negative effects and how to eliminated or reduce it, and to understand the concept and importance of dynamic capabilities and their sub-dimensions on the variables of the research and the And the advantages it has for colleges sample research.
