That is sort of the idea of the MVP (minimum viable product). I prefer the analogy of painting. You start with collecting references, exploring ideas in a sketchbook, make color tests, draw outlines on canvas, use big brushes for colors, refine with smaller and smaller details. The problem is, that programming is all details / only details. There is no easy way to use big brushstrokes, so you have to improvise and not loose the overview. It doesn't help that engineers love details.
