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.
The president of the company related that he is thankful each day for the impact these two informal scoreboards add:
_____ Days since the last late delivery
_____ Shipments since the last late delivery
