Amazon built one of the world’s most efficient warehouses by embracing chaos
First, random storage makes finding the toothpaste faster in an era of on-demand efficiency. If there were a dedicated “toothpaste shelf” and someone ordered toothpaste, a “picker”—how Amazon refers to employees who gather items—would need to travel there, whether he were 10 feet or 100 yards away from that location. But if the warehouse stores toothpaste in 50 different locations, there’s a much better chance that there’s a tube close to some picker. There’s also a greater chance that the second item the customer ordered is also nearby.
