However, the meaning of six sigma does not simply refer to the above statistical requirements, but a set of systematic theories and implementation methods.

6. Pursue perfection, but tolerate mistakes. With the intensification of market competition, customers have become the decisive factor for organizations and enterprises to survive in the competition. Substitute products of the same type are always competing for existing and potential customers. Any product failure and service failure may reduce customer satisfaction, resulting in the loss of customers.
