“While definitions vary, design thinking usually involves a period of field research — usually close observation of people — to generate inspiration and a better understanding of what is needed, followed by open, nonjudgmental generation of ideas. After a brief analysis, a number of the more promising ideas are combined and expanded to go into “rapid prototyping,” which can vary from a simple drawing or text description to a three-dimensional mock-up. Feedback on the prototypes helps hone the ideas so that a select few can be used.”
