Having done entire startups with release-early, release often approaches, I disagree. Customer feedback, used well, increases efficiency because you can test customer and product hypotheses, allowing you to stop working on the things that aren't worth investing in. Is it true that you can be incoherent like this? Sure. But people doing waterfall approaches can also build incoherent projects divorced from actual needs. But it's perfectly possible to build a solid product and a good business model releasing early and often.
