Prototyping and user testing is the best way to create successful products, but many designers skip this important step and use gut instinct instead. By explaining the goals and methodologies behind prototyping―and demonstrating how to prototype for both physical and digital products―this practical guide helps beginning and intermediate designers become more comfortable with creating and testing prototypes early and often in the process.

Author Kathryn McElroy explains various prototyping methods, from fast and dirty to high fidelity and refined, and reveals ways to test your prototypes with users. You’ll gain valuable insights for improving your product, whether it’s a smartphone app or a new electronic gadget.
