After nearly 60 years of activity of the National Planning Organization; an institution that from the beginning was responsible for the role of planning and development and strategic supervision of the country's economic and social system, this organization was dissolved in 2005 by the decision of the government of the time. The National Management and Planning Organization itself needed reform and evolution in order to be updated and fit with the environmental conditions, but its dissolution had detrimental economic, social and political consequences. The government, the people, the 1404 Vision Document and the country's development goals were the main victims of this dissolution; after the dissolution of the Management and Planning Organization in 2016, the Management and Planning Organization was revived and started operating in a new structure and in the form of two "Planning and Budget Organization" and "Administrative and Employment Organization". In this research, which has been conducted using a descriptive and analytical method, the reasons for the supporters and opponents of the revival of the Management and Planning Organization have been analyzed and examined. The results of this research show that the elimination of the National Management and Planning Organization created a serious disruption in the country's development path and the achievement of the goals of the twenty-year vision document.
