“A Designer works on a conceptual design with the customer. Then he works out a detailed design into a prototype that can be tested. So far so good. But what goes wrong is that the Usability Engineer is often disconnected to either the design concept or the detailed design. The usability engineer ends up suggesting new designs that totally contradict the conceptual design. The designer is gone. The engineering team implements the changes and the result is a Frankenstein’s monster that despite the best UX resources, fails in the marketplace.” (Jonathan Arnowitz – User Experience in Arnoland)
