In previous studies on the quality issues such as quality improvement, ISO and TQM had approached to the quality and its process independently. So they surveyed two problems in the same questionnaire simultaneously. This study raised a question whether the quality of a product is considered without its process problem. In other words, quality could not be explained separately without considering the process improvement. In order to prove this issue this study performed a empirical survey using a questionnaire to the 300 firms which included several questions on the relationship between the quality and its process. However 98 questionnaires were collected and analyzed with SPSS. After processing the questionnaires this study found that the process and the quality were highly correlated and could not be explained their effects separately.
