Key takeaways
Short answer: Poka-yoke prevents the mistake — a fixture that only fits the right way, a sensor that blocks a missing step. Jidoka detects a defect or abnormality and stops the machine automatically so the problem is fixed before more bad parts are made. Poka-yoke stops the error; jidoka stops the line. Together they build quality at the source. See also oee for manufacturing.
Poka-yoke cannot catch every failure mode; jidoka backs it up by stopping the moment something slips through. Prevention plus an automatic stop means one defect, not a thousand.
Design poka-yoke at each workstation; wire jidoka so the machine halts and calls for help on any out-of-spec signal. Both are quality-by-design, not inspection-after-the-fact.
Jidoka trades a small Availability stop for a large Quality gain — far cheaper than scrapping a batch. It is why OEE Quality on jidoka lines stays high.

No — poka-yoke prevents, jidoka detects and stops.
It costs small stops but saves big scrap — net positive.
Any mistake-proofing — fixtures, shapes, checklists count.
Poka-yoke to prevent; jidoka to catch what slips through.
