We are confident in our abilities, and we know too much about how to make good products without spending years of time and millions of money on it. In the courses of IT giants, they will definitely tell you that you need to conduct research on every pixel, do 10,000 tests with button placements, conduct 300,000 user interviews, and so on and so forth. As it turned out, we are practitioners, not theorists, so we leave all this to those who spend six months agreeing on a palette for the color of icons in the interface. We, on the other hand, will do it better without any research, but in 15 minutes. That's just how it happened.
