Tim states the reason for the iterative, non-linear nature of the journey "is not that design thinkers are disorganized or undisciplined but that design thinking is fundamentally an exploratory process; it will invariably make unexpected discoveries along the way, and it would be foolish not to find out where they lead." Bon voyage!
