This document discusses how new technologies like 3D printing, robotics, and digitization will disrupt electronics design and manufacturing through the emergence of a "software defined supply chain". It provides examples of how these technologies could lower costs, reduce minimum production scales, and in some cases lower environmental impact. While the effects will vary by industry, companies should prepare for more localized, flexible, and software-driven supply chains. The full report from IBM will be available in July 2013 with more details on how different products and industries may be impacted.
