On Tuesday, the team switched from problem to solutions. Instead of a raucous brainstorm, people sketched solutions on their own. And it wasn’t just the designers. Tessa Lau, the chief robot engineer, sketched. So did Izumi Yaskawa, the head of business development, and Steve, the CEO. By Wednesday morning, sketches and notes plastered the walls of the conference room. Some of the ideas were new, but some were old ideas that had once been discarded or never thought through. In all, we had twenty-three competing solutions.
