Poka-Yoke at Starbucks IN Japan

This is the last solution Starbucks has come up with to prevent milk allergy incident in their shops in Japan.

The following card reads:

 “Please hand this card to our barista at the handoff. We sincerely serve our soymilk beverages to our customers by using this card to prevent milk allergy incident.”


When you picked up the beverages, the barista made sure to collect the card and to clearly handoff the soymilk based latte to me. Great example of using Lean thinking to delivery high quality and defect-free (POKA-YOKE) products to the customer.
