Study Notes

Control Phase: Mistake Proofing (Poka-Yoke)

Mistake Proofing is a cost-effective and reliable control method to ensure key Xs remain at optimal project-defined settings.
It can also be used directly on the Y.
Mistake Proofing:
- Prevents error occurrence
- Prevents defect occurrence
- Ensures effective action if defects occur
- Requires little or no formal training
- Is cost-effective and easy to implement
The Japanese phrase "Poka-Yoke" means "to avoid" (Yokeru) and "errors" (Poka).

Importance of Mistake Proofing

Improved quality and customer satisfaction
Prevents error occurrence
Prevents defect occurrence
Ensures effective action if defects occur

Implementation Road Map for Mistake Proofing

Describe the defect or potential defect, including the rate
Apply 5 Whys analysis to error conditions to determine root causes
Identify where the defect is likely to occur (Process Map)
Analyze current tasks associated with the operation
Identify error conditions contributing to the defect (FMEA)
Verify the efficiency of the Mistake Proofing actions

Mistake Proofing Strategies

Detect defects before they move to the next step
Detect errors during processing
Prevent errors from occurring

Mistake Proofing Considerations

Don't make surplus products
Eliminate, simplify, or combine operations
Use one piece rather than process batch flow
Involve everyone in error and defect prevention
Create an environment that emphasizes quality work, promotes involvement and creativity, and strives for continuous improvement

Common Examples of Mistake Proofing

Guide pins of different sizes
Checklists
Optical magnification
Asymmetric parts
Build error checking into control logic
Exact part count
Overlay templates
Color coding (boxes, work areas, products, components)
Spell check
Limit switches
Error alarms
Counters

Mistake Proofing in Business Processes

Mistake Proofing is the primary means of control for many business processes.
Examples include:
- Check digits
- Pull down menus
- Check sheets
- One over One
