“If only one of twelve pulls of the Andon Cord stops the assembly line for a genuine problem, you might think the company would be upset by wasting supervisors’ time chasing the eleven false alarms. It turns out that the opposite is true. A pulled Andon Cord that does not identify an actual error is framed as a useful drill. The false alarm is instead experienced as a valuable learning moment, a welcome education on how things go wrong and how to adjust so as to reduce that possibility. This is not a cultural nuance. It’s a practical approach. Every Andon Cord pull is seen as a valuable episode that in the long run saves time and promotes quality.”
