Who has seen the wind? A Poem by Christina Rossetti www.poetryfoundation.org Who has seen the wind? Neither I nor you: But when the leaves hang trembling, The wind is passing through. Who has seen the wind? Neither you nor I: But when the trees bow down their heads, The wind is passing by. The Wind Rises windtreesseeing
The rational model of design Engineers seem to have a clear, if usually implicit, model of the process of design. It is usually an orderly model of an orderly process as the engineer conceives it. The notion that the design process should be modeled as a systematic step-by-step process seems to have first developed in the German mechanical engineering community. Herbert Simon independently argues for design as a search process in The Sciences of the Artificial. He was motivated to lay out a strictly rational model of design precisely because such a model was a necessary precursor to automating design. His model remains influential even if today we recognize the "wicked problem" of original design as one of the least promising candidates for AI. In software engineering, Winston Royce independently introduced a seven-step Waterfall Model to bring order to the process. In fact, Royce introduced his waterfall as a straw man that he then argued against, but many people have cited and followed the straw man rather than his more sophisticated models. Even if ironically, Royce's seven-step model must be considered one of the foundational statements of the Rational Model of Design. Frederick P.
