To improve efficiencies in your DC, try this unlikely advice: Just stand there

During a recent assignment in a distribution center, I noticed a picker putting a piece of paper over part of the barcode every time he scanned a book. When I asked him why, he said it was because the warehouse's scanning system would get confused by the dual numbers - one a UPC code, the other an ISBN - on the label. The worker didn't realize that this glitch had been fixed two years ago, but no one ever bothered to tell him. So he continued to employ this productivity-draining practice.
