What did Bunnie Huang have to do to make Chumbies appear? What did FitBit have to do to make FitBits appear? This book lifts the curtain on the process of product development, from prototyping to production. Product development is the magic that turns circuitry, software and materials into a product, but the task of efficiently moving from good idea to manufactured product is more dark art than sleight of hand. Author Alan Cohen takes you through each step the process by developing an example product. You'll learn about manufacturing scales from "proto-duction" to low-volume, medium-volume, and high-volume production. Move from prototyping to sample production, and then on to larger scale production. Delve into product planning and budgeting. Understand how to deal with overseas manufacturing. Discover how to source parts.
