A manager at Toyota is delivering a quarterly update to an executive. He’s enthusiastic because all the metrics are trending up and to the right. They shipped on time – sales, and customer satisfaction numbers are up too. The executive patiently listens until the manager is done and then asks: “So where are the problems?”
The manager explains that it was a great quarter and that there are no problems to report. The executive shakes his head and says: “No problems is problem”.
This is the famous Toyota “no problems is problem” story that is often retold by lean consultants to highlight one of the key tenets of running lean.
