Surprisingly, the task of order picking is, by far, the most costly activity in a typical warehouse fulfillment setting. The only way to reduce this cost while maintaining a functioning operation is to increase the efficiency of picking itself.
Indeed, picking is often a hidden cost center. More than building operation and maintenance, more than inventory management, more than shipping, its the fulfillment activities, including picking, that can erode the bottom line. That’s because they are the most manual-labor intensive activities, with the most room for variance and error.
