Poka-yoke
This seems like an interesting and useful process design concept on one hand, and on the other hand, it also sounds like a Japanese buzzword for foolproofing (in fact, the article notes that the term was originally “baka-yoke”, which is literally “foolproof” or “idiot-proof”). On the one hand, I don’t think Toyota invented the concept of foolproofing; on the other hand, giving it a cool buzzword gives you an excuse to talk about it, which means you’re more likely to actually do it when appropriate.I’m also kind of amused at how the entire business world basically said, “man, this company made super reliable cars in the 80’s and 90’s[1], let’s learn their secrets” and it turns out that once you strip away the exotic Japanese veneer, it’s mostly just systemized common sense. Which is not a minor thing to do, to be fair, except it’s easy for businesses to take good, well-systemized ideas and utterly misapply them.[1] As far as I know, they still make reliable cars. But you can still drive a 92 Camry today if you wanted to with little fuss. By definition, we’re 26 years away from seeing if today’s Camry is quite that reliable.
