Black rakuware tea bowl (late sixteenth century), Kyoto, Japan. Freer Sackler Museum of Asian Art.
For Irwin, the lesson of [the raku tea cups] was twofold: first, their presentation was important, insofar as the ceremony involved a gradual preparation of the audience's aesthetic attention. Then, when the time came to handle the cups, the intimacy of the experience fused visual and tactile sensations into a single continuum. As he also noted:
he would set on the table this box with a beautiful little tie on it – very Japanese – and you untied it, you opened up the box, he let you do that. And then inside of it was a cloth sack. You took the sack out, and it had a drawstring, and you opened up the drawstring and you reached inside and took out the bowl. By that time, the bowl had you at a level where the most incidental detail – maybe even just a thumb mark – registered as a powerful statement.
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.
