I equate design to usability. A bad design and UI = bad usability.
For our current project I gave some feedback on issues I had with the presentation, citing usability problems because the design is wrong and I wanted to spend more time designing it in a way that makes sense and flows better.
My boss and manager responded with "functionality over design". And if they want a better design they have to pay more. But that means giving them a product that is overly messy and complicated to use. It wouldn't be a big job to improve the design.

Any thoughts on this?
