A practical guide to prototyping as a way to revolutionize your work and creative life, from Stanford University's world-renowned Hasso Plattner Institute of Design, aka the d.school. Prototyping is a way to test an idea to see if it can be successful before investing too much time and too many resources. But it's not only designers who prototype as they work. A skateboarder tries a new trick; that's a prototype experience. A chef experiments with a new dish and new ingredients; that's a prototype experience, too. Once a prototype is made, the creator gains knowledge about what worked and what didn't, what should be used again and what should be trimmed from the experience. This is a book about becoming better at prototyping by building things and experiences that will help you learn from your attempts, no matter what you're aiming to achieve. Readers will learn how to not only create prototypes but also how to reflect on the success and failure of those attempts. Scott Witthoft, who
