Quality
Jidoka
自働化Japanese
Automation with a human touch: machines and people stop automatically when an abnormality occurs, so defects are not passed on.
Jidoka is one of the two pillars of the Toyota Production System, next to Just-in-Time. It builds quality into the process instead of inspecting it in afterwards.
Examples
- 01A press stops by itself when a sensor detects a double sheet.
- 02An operator stops the line when a part does not fit and calls the team leader.
- 03A filling machine stops when the weight deviates more than 2 g from 500 g.
