Poka-Yoke, pronounced polka-yokay, is Japanese for Mistake Proofing or Error Proofing. It's a lean tool that can be used to reduce or completely eliminate mistakes.

Some examples of Poka-Yoke that we have setup in the shop

  • RFID scanner to ensure correct gear is checked out for the order.
  • Kaizen Foam to ensure proper placement of tools.
  • Making Hampers Barcode only so that they do not accidentally get scanned.
Example of Poke Yoke in a Surgical Setting, hoses can only be plugged into one hole
