> I'm all for good software design, but claiming a design process can eliminate bugs is more fantasy than reality. Bugs typically come from unforeseen requirements or application states.

In my experience, that's only true code that's relatively well-engineered to begin with. Unfortunately, there are lots of bugs in real-world shipping software that have nothing to do with an unforeseeable environment, but are only the result of unnecessarily complex designs that even the original programmer hadn't completely thought through. So while good design might not eliminate bugs, bad (or no) design can definitely create them.
