I’m reading a second book on design thinking. This one is called “The Art of Innovation,” by the former CEO of IDEO, one of the world’s top design firms. I continue to be most fascinated by the chapters on physical space. Many leading-edge companies — including Pixar, IDEO, and Ericsson — have spent a lot of time and money fashioning workspaces that foster creativity, communication, fun, and esprit de corps. They describe these spaces as neighborhoods, parks, commons, clubhouses, greenhouses, huddle rooms, campfires, and cul-de-sacs.
