I really had to fight with this drawing to get it to work the way I wanted. In the end I ended up in a very different place than I set out to go. The great thing about getting there was that it revealed a new even more distant summit to climb. I also read this quote recently and thought it was appropriate.
"Traditional problems are best solved by analysis followed by action. In contrast, complex problems are best solved by action followed by analysis. Traditional problems can be solved through modeling and optimization. However, complex problems are best solved through experiment and iteration."
