Prevailing Low level of materialization of urban plans in the country may not be denied. The issue may be studied from the two following perspective: formulating efficient strategies and proper implementation of strategies. Proper formulation of strategy is related to plan and appropriate implementation of strategy is related to management. Therefore, in process of urban planning and management, formulation steps of plans and extraction of strategies have to be redefined. On the other hand, streaming strategies has to be explained as the neglected dimension in process of urban planning. In the research, effort has been made for the reasons of failing urban plans in implementation phase to be studied. Data have been collected and interpreted through library study, analyzing documents and expert views. Finally, a model has been proposed with emphasis on futures studies in urban planning. In the model, effort has been made to consider factors effective on failure of plans; and, to respond to those cases recognized as obstacles of materialization of plans.
