jidoka

This concept, also known as jidoka, was pioneered by Sakichi Toyoda at the turn of the twentieth century when he invented automatic looms that stopped instantly when any thread broke.

Two of the basic lean concepts in physical production—automatic machine and line stopping whenever a mistake is made so no bad parts will be passed forward to interrupt the downstream flow (which Toyota calls jidoka) and a pull system so that only parts actually needed are made (which Toyota calls Just-in-Time)—had been formulated by Sakichi Toyoda (the founder of the Toyota group) and his son Kiichiro Toyoda (first president of its offshoot, the Toyota Motor Company) in the 1920s and 1930s.

The technology needed for jidoka is now widely available, but we still frequently visit operations where large numbers of employees are simply watching display screens and instrument panels on individual machines, ready to react if something goes wrong.

He decreed that Toyota would implement jidoka techniques and poka-yokes in all production steps so that it would effectively be doing 100 percent quality inspection at the exact moment of manufacture.

In the early years of development of the Toyota production system, jidoka had particularly striking effects because it meant that workers no longer needed to watch machines in order to avoid producing large numbers of defective parts.

With proper use of jidoka they could instead be performing preventive maintenance and routine housekeeping or tending to logistics.

On the last page of the interview, Taiichi Ohno talks briefly about quality control and jidoka.

As long as tatk-flow-pull and jidoka (stop and fix, escalation system etc) are in place, it is not so important whether the line moves continuously, moves by pulse (remains stopped and advances every takt), or move the people/jigs/materials while keeping the work pieces in-line but stationary - sometimes used for massive products like mining trucks.

Sakichi Toyoda developed another concept, jidoka, or "automation with a human touch."

Our other great accomplishment in eliminating waste was using jidoka.
