19、neglecting those errors. It follows that mistakes will not turn into defects if worker errors are discovered and eliminated beforehand.” 缺陷的產生是一些環(huán)境或者行為導致的結果，但是完全有可能通過查 找原因排除缺陷。缺陷原因在于工人，缺陷是因為工人忽視錯誤而產 生的。如果工人能及時的發(fā)現錯誤并且消除錯誤，就不會導致缺陷的 產生。 Shigeo Shingo Why Error Proof? 為什么防錯？ 99.9% Error Free Could Resul
