The objectives of this research were ambitious: the definition and development of a structured methodology that: 1. captures the total environment of complex architectural design problems; 2. enables the many parts and interests in an architectural development to communicate and understand each other; 3. provides a framework that can embrace the many sub-problems and conflicts that are bound to arise during the definition and appraisal of a design; 4. provides a sequence of procedures that enables a design to be elaborated that both solves the technical problems and induces consensus between the interests.
