This document discusses agile hardware development. It notes that agile development allows ideas to progress from prototypes to mass production more quickly through the use of tools like Arduino, open hardware modules, 3D printing, agile manufacturing, maker groups, crowd funding, and social media promotion. It also discusses Seeed Studio's growth from 2008 to 2013 through working with makers. Finally, it outlines some methods for efficient open hardware supply chains including mass prototyping, quality control, and supply chain management.
