"You have an implicit assumption that rapid iteration means poor quality control. It doesn't have to." I would actually go a step farther and assert that strong quality control facilitates rapid iteration. My 15 years of experience in software bears this out -- the (extremely rare) projects with quality control were far smoother than the ones without. In ones without solid QA, the software become so convoluted and messy that rapid iterations became entirely infeasible. There was no way to change the software without re-writing large chunks of it, or putting in a large collection of hacks that broke as much as they fixed.
