Tehran’s structural-strategic plan adopted in 2007 is the last comprehensive plan in Tehran which was developed based on new paradigms and strategic planning approaches; this plan covers not only traditional subjects of comprehensive plans but also includes such major issues as changing urban structure and functions, reforming revenue system of Tehran’s municipality, bolstering urban infrastructures, improving urban transportation system efficiency, providing safety and security for the city against natural disasters, improving urban environmental quality and using modern land use planning approaches. This article aims to evaluate the development process of this plan by considering foresight approach indicators and principles and proposing to reform this existing trend using the foresight approach. The main paradigm of this study is interpretive, which falls under qualitative research. Data are gathered by surveys and semi-structured interviews, and open-ended questionnaires while they are analyzed by Delphi techniques and structured qualitative content analysis. Indicators and principles of the foresight approach are elicited using the Delphi method, which includes regard for stakeholders and beneficiaries (participation), regard for the unknowns, uncertainties, shocks and complexities, regard for trends and megatrends, holism, inclusiveness and universality, regard for plans and low- and high-level document results, a long-term view, regard for values and worldviews, scenario writing and futurism, accurate understanding and analysis of the planning environment and visioning. These principles are categorized using the document content analysis method of Tehran’s structural-strategic plan and are measured by the extent to which they are incorporated into the plan. The results suggest that these principles are less regarded by both methods when developing urban development plans.
