Which of the following statements are correct regarding 'Poka-Yoke'?

A. The term poka-yoke originated with the Japanese Baka-yoke.

B. The contact method of poka-yoke identifies defects through physical attributes.

C. The fixed value method of poka-yoke is used in a process with non-recurring activity.

D. The motion-step method of poka-yoke determines whether prescribed steps are completed in order.

Choose the correct answer from the options given below:

Correct option is D

Poka-yoke is a Japanese term that refers to mistake-proofing or preventing errors in manufacturing processes.

• A True: The term poka-yoke originated from Baka-yoke, meaning "fool-proofing" in Japanese.
• B True: The contact method of poka-yoke involves identifying defects based on physical attributes of the product or process.
• D True: The motion-step method of poka-yoke ensures that the correct steps in a process are performed in the correct order, thus preventing errors in the sequence.

Information Booster:
Poka-yoke mechanisms are used widely in manufacturing to prevent human errors and improve product quality. The goal is to make it impossible or highly unlikely for mistakes to occur. Baka-yoke emphasizes the importance of making systems fool-proof to minimize the chances of human error.

Additional Knowledge:
Poka-yoke can be applied not just in manufacturing, but in service processes and educational environments to ensure error-free procedures. For example, a corrective feedback system in learning platforms can act as a poka-yoke to guide students away from making repeated mistakes.
