Agile UI Design: A Fundamental Miscalculation in UI Design Excellence?

I’ve been banging my head against a wall trying to figure this question out for some time now.  Can existing in an agile development cycle truly create the best ui design? I’ve worked in Agile development environments. I’ve worked with structured project management. I’ve worked in locations where I am the project leader. If there is one thing I have discovered it’s that any process can be carried out so far to one end of the spectrum that quality and more importantly usability, and maintainability go right out the window.
