After 11 years managing freight for a mid-sized retailer, I've automated every step from purchase order to dock door, yet our on-time delivery rate barely moved past 92%. The bottlenecks remain the same: port congestion in LA, trucker shortages in the Midwest, and that one warehouse in Tennessee that still runs on spreadsheets. Software can track a pallet to the centimeter, but it can't unload a ship faster or convince a driver to stay past his hours. So, is investing in flashy supply chain tech actually worth it when the human and infrastructure limits cap your gains anyway?
