Jidoka as a pillar of the Toyota production system
At Toyota, people know that "the right process will product the right results." Therefore, one of the main goals of toyota's management teams is to improve processes by eliminating waste. On the other hand, predicting failures of a given process is nearly impossible. So, the best way to achieve the "perfect process" is to stop the process and fix every small error immediately after it occurs and before it reaches a critical level.
