What are the three error proofing categories?

Shigeo Shingo coined three types of poka-yokes: Contact method – identifies defects by testing product characteristics. Fixed-value – a specific number of movements every time. Sequence method – determines if procedure were followed.

What are the three types of error proofing solution implementation techniques?

Mistake Proofing Procedure

• Elimination: eliminating the step that causes the error.
• Replacement: replacing the step with an error-proof one.
• Facilitation: making the correct action far easier than the error.

What are the types of poka-yoke?

There are two types of poka-yoke: control and warning.

• Control: The goal is to make it mechanically impossible for mistakes to be made.
• Warning: Color or sound is used to alert operators that they are about to make a mistake.

What are the three types of mistake proofing?

The technique or mechanism that prevents or detects errors or deviations is mistake proofing. Shigeo Shingo coined three types of poka-yokes: Contact method – identifies defects by testing product characteristics. Fixed-value – a specific number of movements every time. Sequence method – determines if procedure were followed.

What do you call the process of error proofing?

Error Proofing is also called Mistake Proofing, from the Japanese Poka-Yoke [poh kah yoh keh], sometimes pronounced Poka-Yoke [POH kuh YOKE] in English. It is a technique used to make failure – or potential failure – easy to detect, or to prevent it from occurring in the first place.

How is mistake proofing used in the manufacturing process?

Mistake Proofing or Poka-Yoke methodologies can detect errors and prevent the non-conforming part from moving to the next process or leaving your facility. Furthermore, by implementing Error Proofing techniques to detect the error at the source, we can prevent the non-conforming part or product from being produced.

What is the Japanese term for mistake proofing?

Poka-yoke is the Japanese term corresponding to mistake-proofing. Mistake Proofing is about adding techniques to prevent defects and detect defects as soon as possible, if one does occur.
