He emphasized on the internal customer, meaning that during each step in the creation of a product or service, the department will need to treat the next department as a "customer", so that quality is controlled at every step. This is how Isikawa's method is process-driven because every process is tightly connected to the next.
His quality requirement is customer-driven because he pushed for the concept of company wide quality control that
