Amid the change, one thing remains constant at Amazon: the determination to invent. Automating so much labor has freed Amazon’s corporate staff to concentrate on its invention process (they no longer have to work peak season, packing boxes). And it gives Amazonians inside the FCs the time to invent on their own. In EWR9, Virdi showed me a “continuous improvement” kiosk where employees enter ideas for new products, processes, and minor FC tweaks. Every Wednesday, Virdi and his senior staff review the best ideas for forty-five minutes. When they like what they see, they give their associates time and resources on their scheduled workdays—paid—and ask them to turn their ideas into reality. Associate feedback, to give one small example, led Amazon to make its bins yellow to help them more easily spot products and work more effectively.
