Agree to disagree or I understand your point of view but…
The art of constructive criticism is a talent that you don’t find on anybody’s resume, but this specific skill is very useful where design work is involved and specifically design work with a multitude of parties each having the correct solution to the problem. Maybe Constructive criticism is not quite the right fit, more a doctorate in Spin, were you need to explain to a client that there idea is like looking at a solar eclipse without one of those boxes with a pinhole in it.
If you pull this off and everyone agrees on a solution, say for example that you need 5 categories in your website architecture for a particular product and then create a website design around this new menu and then hold everything…wait… now after seeing it they decide they need 8 categories and another whole section, because that is what xyzproducts.com is doing, “I saw their site over the weekend.” So now you have to explain to them how
wrong “mistaken” they are all over again, subtly of course…. Unless by some freak event you yourself are wrong on this one??!??
“Criticism may not be agreeable, but it is necessary. It fulfills the same function as pain in the human body. It calls attention to an unhealthy state of things.”
