Amazon began automating retail team jobs several years ago. Under an initiative called “hands off the wheel,” the company shifted tasks like forecasting demand, ordering inventory and negotiating prices to algorithms, people familiar with the matter say. At first, humans could easily override the machine’s decisions. For instance, if a brand notified Amazon about an upcoming marketing blitz for a product, an Amazon manager could increase the order in anticipation of demand the algorithm didn’t expect. But such tinkering was increasingly discouraged as the machines proved their precision, the people say. Anyone overriding the machines had to justify their decision, and the push to automate made them reluctant.
