What is the definition of Poke Yoke?

The concept of Poke Yoke is fundamentally about preventing errors through error-proofing techniques embedded in processes and designs. It is most accurately defined as the use of process or design features to prevent errors from occurring in the first place. This proactive approach is essential in manufacturing and service industries where mistakes can lead to defects, inefficiencies, or safety hazards.

Poke Yoke systems are specifically designed to detect potential errors and either prevent them from happening or correct them before they affect the final product or service. This contrasts with simply avoiding inadvertent errors, which does not encompass the systematic approach inherent in Poke Yoke methods.

Furthermore, while enhancing product quality and making changes for future improvements are important aspects of process management, they do not capture the essence of Poke Yoke, which focuses primarily on integrating controls within processes to eliminate the possibility of error before they occur. In summary, the essence of Poke Yoke lies in its proactive design and process features aimed at error prevention, making the second choice the most fitting definition.
