Interesting article.  Scientific theories are often proven to be obsolete -- business should be no different.<p>To me, this article also underscores the ever present friction between theory and practice.  I recently was speaking to an advisor (in academia) and, while his input was incredibly valuable, much of it contradicted what we know to be true based on interactions with our customers.<p>How have you all managed this balancing act?  Is there a place for academic theory in product development?
