Poka-Yoke (Error-Proofing)
Reference model
Error-proofing techniques help ensure processes are foolproof.
About this model
Poka-Yoke, developed by Shigeo Shingo in the 1960s, focuses on preventing errors by designing processes that minimize the chance of human error.
Originator not stated.
How to read it
- Look for areas where errors frequently occur.
- Assess the effectiveness of current error-proofing measures.
What this does
Poka-Yoke is a method used to prevent errors in manufacturing and service processes by designing systems that make it impossible or easy to detect mistakes.
When to use it
Use it when you want to improve process reliability and reduce defects by implementing simple, effective error-proofing techniques.
Not when: Do not use it when the process is too complex for simple solutions or when the cost of implementation outweighs the benefits.
What happens next
Conduct a root cause analysis to identify underlying issues that may still cause errors.
