It is easy to forget that professionalism is the enemy of the high-tech startup. If these companies were operated by professionals, they would never have been founded. Nor would a professional tolerate the conditions necessary for startup survival.-- The Case Against Professionalism
So people who want to replace every bit of a corporation with by-the-numbers modular units, can say they're doing it in the name of professionalism -- because that's what one learns to do in "professional" training at bidniss schools. And people who want to keep a company small and personal, can just as well say they're doing it in the name of professionalism -- because a sense of "profession" is what they say they want to foster, where everyone has close personal ties to their task, and all the people who relate to it.
So when I run into a word like this, I say that no point of contention should ever be expressed using that word, because it's just too imprecise, and that some other (more clear) word has to be used instead.
