Software Like Scrabble

I don't know where did I read this one but talking about how development is not linear, someone was comparing it with scrabble, where you could add words only connecting one letter, and be "ok", but if you really want to get the max scoring, you have to think of synergies (gasp), and symetries, and how to reuse components in multiple subsystems.

I don't remember the exact quote, but I like to think it as well. Although iterating is THE WAY, focus and review of greater goals help you reuse in non-obvious ways. I'm not sure if this goes against TDD, or some other methodology (but it really shouldn't)
