The engineering analogue to Fermi estimation (quick and dirty science) should be called Dyson fabrication, after Freeman Dyson. His ideas like the nuclear rocket had such overpowering leverage in a few elements, they could be sloppy and unoptimized everywhere else.

A good Dyson fabrication allows you to go to extremes in m variables of n-dimensional design space so that you can waste (n-m) variables
For example, a sledgehammer doesn’t really need a smooth face

Could use other examples
I think Starship might be a Dyson fabrication

Something like that though there’s more to it… Ken Browers The Starship and the Canoe was a great read on it
