“Dr. W. Edwards Deming had a profound impact on Toyota in many ways, but one thing in particular stands out: a deep belief that most problems are system problems that are the responsibility of management. Toyota leaders are taught that team members are rarely to blame for an error, but rather there is usually something about the system that allowed the error to occur.”
