Andon

Andon is a visual (and often audible) signal system that lets any worker flag a problem instantly — a light, board or alert that shows line status and calls for help. It surfaces abnormalities in real time so they are fixed before they spread.

An andon empowers operators to signal or even stop the line when they spot a defect or issue, triggering immediate response rather than letting problems continue. It makes the state of production visible at a glance (running, blocked, calling for help) and is a practical expression of jidoka. Modern digital andon ties into MES and analytics for live status and response tracking.
