• BFalse

• B

Explanation

Option A is correct because Jidoka is a core Toyota Production System principle that translates to building quality into every step of the production process by automatically detecting defects and halting the line immediately - the practical result is error-free (or zero-defect) production. Rather than allowing defective units to continue downstream, Jidoka empowers machines and workers to stop production the moment an abnormality is detected, ensuring only conforming products move forward.

Option B (False) is wrong because dismissing Jidoka as unrelated to error-free production ignores its foundational purpose: preventing defects from being passed along, not just catching them at the end.

Memory tip: Break the word down - think of Jidoka as "Ji" (self) + "do" (doing) + "ka" (quality check). It's the machine or worker self-policing for quality, which results in error-free output. Pair it with its nickname "autonomation" (automation + human judgment) to anchor the concept.
