Bruce Nussbaum was right to close the book on Design Thinking. It is time to move on. Business never really got the message. What businesses continue to care about is innovation. While designers may think that innovation requires Design Thinking, that was an idea that never really stuck in the executive suite. Is “creativity” any different? Most executives will acknowledge that innovation requires some form of creativity. But creativity brings its own baggage.
Have "design thinking" and "social innovation" become permanently intertwined? You'd have to think so based on Tim Brown's book and the prevailing discourse at any major design/innovation conference (SXSW, PICNIC, GEL, GAIN, LIFT). There seems to be a firm belief that you can't establish any cred as a designer these days if you haven't applied design thinking to a major social issue of some sort (health, energy, education...). Similarly, it would seem that social innovation (or social entrepreneurship) is hopeless without a designer at your side.
