The progress of Toyota Quality
The Toyota Production System is based on 2 Pillars which are, Jidoka and Just in Time (JIT). Jidoka is “Building in Quality” at the process and JIT is building what is needed, when is needed in the amount needed. Toyota has implemented a process they call for JKK (Jikotei Kanketsu) which means “Building in Quality with Ownership”. Ownership is defined in JKK as understand all the “necessary conditions” and “process criteria” so that ZERO defects are passed on. Toyota sees it from the customer’s perspective. If a customer has defect on the vehicle that rate becomes 100% for the customer but for the company it may be .001% which doesn’t seem too big.
