Both, to me, sound like reinventions of ESR's "the cathedral and the bazaar". I like those definitions and the things they imply: bazaar-style work is simple, easy, and fast, it doesn't require much capital, but it doesn't scale past a certain size -- and it's not going to produce an architecture that can withstand firebombing 700 years after ground was broken for it. I think most people can say pretty accurately whether they're in the "open for business by Tuesday" model of software development or the "700 years and undreamt-of threats" model... But if your product becomes a surprise hit, that's when you refactor your chaotic bazaar into a clean, legible, highly maintainable cathedral.
