Last year saw yet more growth for the warehouse supply chain industry. A growing dependence on e-commerce signals increasing pressure. Digital Commerce 360, citing recent Forrester data, believed that, by 2022, e-commerce will account for around 17 percent of all U.S. retail sales. This number is a sharp revision up from the less than 13 percent stated in the 2017 edition of the report. Given this increase, it is not unreasonable to assume Forrester is downplaying the potential of e-commerce yet again.
