Too Many Cards at the Window

A Split-Tab Payment Quadrant for Automated Queue Resequencing at the Food Truck

A research poster from the School of Continuous Improvement sorts 1,860 food-truck orders across six rows into a split-tab complexity and party coordination quadrant, finding that the busiest cell absorbs most arrival-order overtakes once a resequencing rule goes live, while diners route around the label by tapping cards in quick succession rather than changing what they order.
