초록
The research develps the calculation steps of sigma level, process capability index(PCI) and process performance index(PPI) applicable to the discrete process in the service industy. The paper presents three following topics used related process indexes according to the precision and accuray in the continuous process. The contents include diverse process indexs for nonconformities by SPC attribute control charts and bias coefficient. The same technique of the nonconformites is also used in the nonconforming units. The practical examples are provided to help easier understanding for users.
