Achieving urban and regional development through increasing efficiency of plans is one of the most important objectives for states in the 20th Century. Following the end of World War II and the need to rebuild devastated cities, the comprehensive planning model was criticized for its purely physical, inflexible, and incompatible attention to the rapid changes of urban settlements. Therefore, simple-comprehensive planning replaced with a rational-comprehensive approach, which provided a strategic attitude. In the planning system of Iran, which devised comprehensive planning, it became clear to the planners that rational – comprehensive programs were not realized. Thus, strategic-structural planning was introduced and supported which led to prepare strategic-structural plans for some metropolises including Tehran. The lack of legal and institutional redefinition of this approach in the planning environment (Tehran) caused the preparation process of the plan encountered some problems during the planning process and affected the realization and achievement of the project goals. The purpose of this paper is identifying the institutional deficiencies and contradictions of the Tehran strategic-structural plan (TSPP) with the principles and values of the strategic planning framework to increase its feasibility and efficiency. In order to achieve this goal, first, the present study determines institutional criteria to compare TSPP with strategic planning which can increase the effectiveness of planning institutions. Secondly, a comparative analysis is carried out to determine inconsistencies of TSPP with the main principles of strategic planning. Based on the achievements of this paper, despite the tendency and attention towards institutionalism at all stages of the plan preparation, the plan (TSPP) lacks any action to improve this approach and, in this respect, needs to be revised in both areas of quantitative and qualitative requirements to be realized within the framework of strategic planning.
