Two new books were just published in the MIT Press book series "Design Theory/Design Thinking", that Ken Friedman and I are Series Editors for. Kees Dorst "Frame Innovation - create new thinking by design" and Ezio Manzini "Design, when everybody design -- an introduction to design for social change". These are great additions to the series. Read and think!
