POKA YOKE (ERROR PROOFING)

INTRODUCTION FOR POKA YOKE (ERROR PROOFING)

Poka Yoke is Japanese for error proofing. These Poka Yoke (Error Proofing) devices or systems are used either to prevent the special causes that result in defects, or to inexpensively inspect each item that is produced to determine whether it is acceptable or defective. The life and soul of production of any kind is guaranteed quality and the ultimate aim should always be zero defect.

COURSE OBJECTIVES

At the end of this course, participants will be able to :

• Explain the Poka Yoke system role in zero-defect manufacturing.
• Understand why defects occur in the production.
• Compare and select the best Poka Yoke solution.
• Overcome cultural barriers to socialize Poka Yoke.
• Start with Poka Yoke implementation.
