Before expending excessive amounts of time and resources, an idea can be tested through prototyping to determine its viability. However, not just designers "prototype" as they go along. An example of a prototype experience is when a skateboarder tries a new trick. An experiment by a chef with a novel recipe and novel ingredients counts as a prototype experience as well. Making a prototype enables the creator to learn what worked and what didn't, what should be repeated, and what should be eliminated. No matter what you're trying to do, this book is about improving your prototyping skills by creating objects and experiences that will allow you to learn from your failures. Readers will learn how to design prototypes as well as how to evaluate their own successes and failures. Scott Witthoft introduces a wide range of tools and materials for prototyping, including digital platforms and actual items. Scott Witthoft gives design and prototyping classes to students all over the world. The reader can see both large- and small-scale prototyping in action by reading about real-world instances of prototype experiments and viewing the accompanying images. With Witthoft as your mentor, you'll apply design concepts and realise your vision, one prototype at a time.
