Poka-Yoke防错
Poka-yoke is a mistake-proofing technique or device that prevents an operator from completing a step incorrectly or makes an error immediately detectable before it creates a defect. In manufacturing documentation, the term appears in process design descriptions, work instructions, quality control plans, training materials, and equipment specifications where sensors, guides, interlocks, or visual checks are described as safeguards for repetitive assembly or processing tasks.

Where this term appears
Poka-yoke appears in localized work instructions, operator training modules, quality procedure documents, and machine manuals for assembly and packaging lines. Translators often encounter the term when adapting Japanese lean manufacturing content into English or Chinese, and they must decide whether to retain the loanword, translate it as mistake-proofing, or provide a gloss.
Translation checks
A frequent mistake is translating poka-yoke as 'foolproof' or 'idiot-proof,' which can sound insulting in operator-facing materials and is often inappropriate. Another error is treating it as a quality slogan rather than a concrete mechanism, losing the functional detail in work instructions and making the safeguarding feature unclear to line workers.
