Nice article, thanks for posting it. It's ironic that this article mentions the Toyota Production System as an example of a safe and defect-free system. Another article about Toyota was posted on HN today: «Toyotas Unintended Acceleration and the Big Bowl of "Spaghetti" Code (2013)» http://www.safetyresearch.net/blog/articles/toyota-unintended-acceleration-and-big-bowl-%E2%80%9Cspaghetti%E2%80%9D-code http://www.safetyresearch.net/blog/articles/toyota-unintende... Apparently Toyota's software development doesn't follow the Toyota Production System. OK, that was a flip comment; it's pretty clear that TPS isn't suited to software development. However, it does seem clear that Toyota's software development practices are deficient.
