"Studies show that a key aspect of the creative ways in which designers think and work is problem-framing, or generating perspectives that engender new understanding of the problem and offer bridges to new solutions. Kees Dorst skillfully explains and develops this concept, illustrates its application with real, complex, and contemporary examples, and shows how teams and organizations can work in this creative, innovative, and designerly way." - Nigel Cross, Emeritus Professor of Design Studies, The Open University, UK
