We have let the visual designers run mad and it is killing software.
From my side I'm going to continue excluding UX folk from all future development unless it's an explicitly new-user facing app on a mobile device.
This needs further clarification. What kind of software would that be? I read your previous sentence as "I can do the work UX folk do", but you don't seem to be implying that UX is not important, right?
When you’re looking for a “UX expert” and they are showing you their portfolio, ask them to show how their apps look on a phone in landscape orientation or over a slow dial-up connection, or how their designs work with a screen reader, or for a colorblind user. If they say “oh, that’s a problem for the Accessibility team,” RUN away from that candidate!
Also, what was the methodology used to decide the particular UX solution to the problem?
A UI designer is tasked with making a UI beautiful, a concept that is highly subjective. A UX designer is tasked with making the UI functional, which is far less subjective.
Guess which person the management takes more input from?
Because, unless today, the additional space will not be filled with useless hamburger menus but it will be used by the main working area.
But why optimise for an 800x800 resolution (which would essentially give you lots of empty real estate if you have a higher resolution)? I really don't get this post?
