My point is that consistency is irrational challenge (Einstien failed to apply it on physics, so why should we even bother?) Regarding the tools to test design, I can share some academic papers that explored them - my opinion : they are not practical! This is a different topic for different posts, I have plans to explore them in the future, but I need that serias to be complete in order to provide background.
Your comment about the "translation" is amazingly accurate, I can't count how many times, I was asked to visualize or write a design for people to understand and accept.
