It's a common challenge during peak Holiday season. Every year, thousands for warehouses across the world ramp up for an explosion of shipping that challenges even the most sophisticated warehouse managers. By some estimates, Catalog and E-Commerce businesses generate nearly 60% of their annual sales in the last four months of the calendar alone.
One common "challenge," which might be considered a "good problem to have" is the "hit product" where there are hundreds or even thousands of orders every day for a single product that everyone wants...or wants to give as a gift. When there are so many single-item orders for the same item like this, it seems wasteful to run all of them through the standard picking, sorting and packing process that a typical order would go through.
