This document discusses the history and principles of design thinking. It emphasizes that the best ideas emerge from an environment that allows experimentation across disciplines, with a focus on customer needs rather than individual departments. Great designs consider technical, commercial, and human factors. Design thinking involves divergent and convergent thinking - generating many options and then making choices. It is important to observe people, gain empathy, and consider what is not said or done. An interdisciplinary team working in a supportive environment is needed to drive innovation through design thinking.
