Good story!
I see the problem from the other side, however ;)
The ‘UX’ (which by the way is probably User eXperience — so a bad naming convention from the start) is helpful while trying to build something entirely new. But that’s a rare thing. If you’re building a digital product chances are you’ll have a registration process, a login page, some sort of a dashboard etc.
Now the actuall “right way” of doing these things already exists for most cases. There are some edge-cases of course and they need to be studied, but it’s not reinventing the wheel.
The intangible part of this is important but I think it’s not even UX anymore but more of a “Business Relevance”. Does it make business sense (from both the company perspective and it’s users — will they want / need it).
And the other side of the coin is that in many cases people focus on spending countless hours on defining a registration flow + talking about it and then they create buttons that don’t fit on screen or are crooked. The poor UI is a nearly universal problem, while I have only seen a couple of products recently that have “terrible UX”. Most of them are “OK”.
But they are UGLY or mediocre at best, and that doesn’t inspire confidence in their brands or their overall quality.
UI is an important part of the process and having a person who can think about the intangible and wrap it in the tangible is the most beneficial ways to build “good s**t” :)
