Last year, I had the pleasure of attending Usability Week in San Francisco which is put together by the usability firm, NN/g. King of usability, Jakob Nielsen, (the first N in NN/g) has posted, what I believe is, the definitive answer to the question of whether to tweak an existing UI design or completely redesign it from scratch. As a designer, I obviously gravitate towards the redesign but Nielsen does a great job of pointing out that redesign for redesigning’s sake is a bad idea. He believes that only when your site/app has become overgrown and unusable, is it time for a radical redesign.
