Retail Sales Process Improvement Using Data (Quality)
Over the last year or so, I've noticed improvements in Costco's point of sale process. First, they noticed that items under the shopping cart were sometimes overlooked by checkers, so I saw them install bar codes on the front of each shopping cart- just inches off the ground between the front two wheels. Each checker had to scan the bar code to show that they had checked the bottom for items and scanned them. This seemed to be an improvement and I imagine that this bar code could also be used to inventory the carts as well.
