Prototyping 
A Practitioner’s Guide

Prototyping is a great way to communicate the intent of a design both clearly and effectively. Prototypes help you to flesh out design ideas, test assumptions, and gather real-time feedback from users. With this book, Todd Zaki Warfel shows how prototypes are more than just a design tool by demonstrating how they can help you market a product, gain internal buy-in, and test feasibility with your development team.
