With eCommerce exploding globally managing fluctuating order volume has quickly become common for many distribution centers. Color Picking is a simple and flexible pick-to-light solution allowing distribution centers to scale labor and workflows proportionally. Based on the principles of pick-to-light technology, Color Picking guides multiple operators through the picking process using colored pick-and put-lights allowing distribution centers to add or reduce labor resources to meet current order demand. When demand is high, Color Picking allows multiple workers to pick from dynamic work zones using pick-to-light technology for higher throughput. When demand is lower, the pick-to-light technology can be operated with only one worker. This allows organizations to easily scale their labor force to meet peaks in order picking demand.
