“So before working to design the thing right, we must first be sure we’re designing the right thing. This calls for a process of diverging and converging twice. The “Double Diamond” asks us to discover many possible paths and goals before we define the problem and craft the plan; and then to develop and test prototypes before deciding upon and delivering the solution.[ 45] Figure 1-8. The Double Diamond. At the heart of design is our ability to model the world as it is and as it might be. This is powerful. A sketch or prototype can spark insights and change minds. Goals and vision may shift in a “now that I see it” moment. In recent years, business has begun to adapt these practices to strategy and planning under the aegis of Design Thinking. Post-its and prototypes engage our brains, bodies, colleagues, customers, and ecosystems in distributed cognition. Design helps us solve wicked problems by exploring paths and goals. And it works for individuals and teams, not just big business. In short, design is a great fit for planning, and its practices are the inspiration for this book.”
