A discussion of traditional approaches to design forms the basis for the presentation of a methodology for architectural design. In particular, the sequence of analysis-synthesis-evaluation is given as being indicative of most design approaches. Variations of this sequence are examined and the importance of correctly ordering parts of any methodology is adopted as a major concern. The proposed methodology is viewed in terms of sequence and has the following elements--(1) recognition of existence of a problem, (2) definition of problem, (3) collection and analysis of pertinent information, (4) synthesis of information into possible configurations, (5) selection of a solution, (6) implementation of solution, and (7) re-evaluation of solution. Necessary aspects of this system which require particular approaches are dealt with in a review of value systems, activity prediction means, and environmental control principles. (RS)
