Detailed plan is the most guiding and systematic tool for implementation of a city master plan. Despite of its importance certain evaluation of its efficiency has rarely been done. In order to fulfill the objectives of a detailed plan, its success, strengths and weaknesses should be scientifically assessed. There is a gap between planning of a detailed plan and its execution, resulting from the missing link in the PROCESS of urban planning and the implementation of urban plans.Therefore, to achieve a dynamic continuous and flexible planning and minimize the gap, the evaluation of detailed plans before and during the PROCESS of its implementation is a necessary task for urban managers.This paper aims to assess the detailed plan of region 6 of Shiraz by using an integrated method. By studying comprehensive methods for evaluating urban plans and reviewing the literature related to the different methods and techniques, a combination of the two methods of "Plan PROCESS Result" and "Plan/Policy Implementation Program" are selected for assessment the efficiency of the mentioned case study. The next step was to introduce and select the suitable evaluation criteria according to the situation and the conditions of the detailed plan of region 6. The detailed plan of Shiraz was first prepared by one of the consulting urban planning firm in 1372 and revised in 1383. The main aim of this new plan with regard to region 6 was to enhance the importance of the region in the West of Shiraz. To do this, the objectives of improvements of physical, environmental, social and urban management based on public participation were considered To gather and analysis the data needed for the study, different techniques had been used such as content analysis of master and detailed plans related to the selected criteria, interview techniques and some field studies. Factor analysis and analyzing strengths, weaknesses, opportunities and threats (S.W.O.T) and also AHP method are used for examination of the procedures. The results of the study show that the conformity, internal and external consistency have gained high score in relation to other criteria such as connectivity, urban development direction, human and financial resources and user participation which the two latter have got the lowest scores. AHP method was selected for determining the weight of the criteria the scores are as below: conformity (./26), internal consistency (./38), connectivity (./.96), external consistency (./145), Urban development direction (./.43), human and financial resources and commitments (./.27) and public participation (./.41).To reduce the deficiency of detailed plans, it is recommended to use social plans for a better public participation in urban planning. Also a systematic approach and providing strategic plans instead of physical plant are useful.Increasing financial resources and paying attention to local organization are the most important tools for managing the implementation of detailed plans. The results In addition to examining the strengths and weaknesses of the preparation and implementation of the detailed plan, the PROCESS of urban detailed project evaluation suggests that it can be used in the evaluation of similar projects.
