So where do you iterate? Most plans don't survive contact with reality, and all that.

  To elaborate a little, I told them that usually during this process you'll bounce back and forth a little bit. You'll notice while your coding something up there was something you didn't understand and so you drop back, understand, and then move forward again. So there's some back and forth, but hopefully general progress is forward. As for iteration, there's a little bit of iteration in every phase. But there's also iteration over the entire process. Once you've understood the problem, come up with a plan, coded it up, and look back to see what could have been done better, it might be time to re-understand the problem.
