Abstract :
Adaptive iterative problem-based approach is an innovative methodology that helps implement programs and projects in the context of development. This approach is based on new ways of implementing practical measures for complex problems and is a kind of foundation for the problem-based approach. Urban organizations and policymakers feel helpless in the face of a variety of unresolved issues, issues that often have large budgets and large plans approved and implemented to resolve them, but in practice, nothing specific has happened to adjust or reduce the dimensions of those issues. The issue of traffic, air pollution, water supply, informal construction, land grabbing, land use change, loss of breathing space in cities, encroachment on private lands, unstable income, etc. are some of the issues that urban development policymakers and organizations are content with reporting only on the number of meetings held, the number of approvals, the amount of budget allocated, the number of votes cast and destroyed, and the like. The continuation of this situation will also erode the remaining executive capacity of the organizations. The approach introduced in this article is a strategy for rethinking the way problems are defined and steps taken to gradually adjust them, although it should be noted that the scope of this method is far beyond the scope of dozens of articles. However, an attempt has been made to examine, as an introduction, an important issue in Iran's metropolitan areas, namely the protection and sustainable development of Tehran's privacy, and to introduce the importance of this approach in changing the perspective on identifying and adjusting urban problems. The findings of the article show that this approach has a high capacity for identifying and gradually adjusting complex problems in metropolitan areas, and it is appropriate tand identifying problems and gradually adjusting them.
