Interpreting parameter analysis through the proto-theory of design

The parameter analysis methodology of conceptual design is interpreted through the reconstructed proto-theory of design, which draws on the similarity of design and geometrical analysis, as suggested by Aristotle. The notions of the proto-theory are found to create added clarity when applied to this contemporary design approach. Especially, they allow interpreting each of the parameter analysis steps separately in terms of the types of reasoning involved. Also it is clarified that reasoning backwards towards a solution and reasoning forwards towards the proof are integrated into one process.
