Y - the concept of frequent validation differentiated the stuff I’ve worked on that’s done well from the stuff that didn’t. Put a different way: the items that we didn’t get good validation on had to landed with a thud in market, or needed to make sizable changes before they were accepted. The items we validated effectively had to make the same changes, but we got there in smaller steps with less pain.

Also: don’t forget business model validation. Having great tech that sellers won’t sell, or customers can’t buy is a tremendous waste.
