If your code quality is bad, you can't do that efficiently. Your developers will hate their jobs and churn like crazy.

And by "bad quality" I don't mean "not unit tested" or "not commented" or "poorly formatted". I'm talking about code that is difficult to reason about, difficult to debug and difficult to refactor or extend. This is hard to quantify or even verbalize. It has to be felt.
