Introduction

It is hard to believe that the current approach to Japan’s quality improvement programme has changed the balance of the present trade situation between Japan and the rest of the world. It is evident that one of the most important aspects of Japanese quality improvement is the Japanese approach to quality management. Japanese companies have developed quality improvement (QI) in various stages, that is, from inspection after production to new product development through the stages of process control. The Japanese way of QI has been described by Ishikawa (1985), Sullivan (1986) and Yoshizawa (1987) who have pointed out the importance of the seven stages of QI. Even now, the value of effective QI has not been fully realized by many industries. In fact some people still think that it is the role of a quality department. They do not realize that QI is a way of life and the human aspect of it requires a great deal of education and training at all levels.
