Design, it seems, is not only becoming more methodical but also more scientific. This is not surprising. Design as a discipline has moved from “product beautification” to being a central part of product development. It has incorporated methodologies from human-computer interaction, sociology, and anthropology as well as advertising and management. And with the rise of design thinking, a wider range of professional disciplines are using creative methods.
I don’t want to criticize design methodologies. But against the backdrop of an overly structured design process, it is important to remind our community that there is one fundamental aspect to design that cannot be formalized in a methodology. And that is intuition.
A Fermi estimate is a quick-and-dirty solution to an arbitrary scientific or engineering analysis problem. Fermi estimation uses widely known numbers, readily observable phenomenology, basic physics equations, and a bunch of approximation techniques to arrive at rough answers that tend to be correct within an order of magnitude or so. The term is named for Enrico Fermi, who was famously good at this sort of thing.
…It struck me that there is counterpart to this kind of thinking on the synthesis side, where you use similar techniques to arrive at a very rough design for a complex engineered artifact. I call such a design approach Dyson design, after the physicist Freeman Dyson, who was one of the best practitioners of it (not to be confused with inventor James Dyson, whose designs, ironically, are not Dyson designs).
