Finally, managers discovered two scoreboards that made the difference. They introduced the scoreboards and then put them up on a white board at the loading dock. Within a year, on-time deliveries soared from 20% to 90%. Teamsters started talking to other drivers about road conditions. Some drivers even came in on a day off to share information about roads with drivers just starting their delivery routes.

_____ Days since the last late delivery
_____ Shipments since the last late delivery
