And I should add that more startup and new-product teams should be bold about throwing away code. Startups need to be optimized for learning. Each release should tell you something about your users, your market, your ideas. But doing that means that some of the code will have been written before you know what you're doing. That code either needs to be refactored or reverted. The latter feels scarier but is often cheaper.
