田口玄一の主張とその実践的社内展開の研究

抄録

Internal deployment of quality engineering at IHI began in 1994 and has continued up to the present. Despite the passage of some seventeen years, the current level of deployment could not be called adequate. To clarify the issues involved in taking the internal deployment of quality engineering to a higher level at IHI and see how to deal with them, a case study was carried out, using a case in which quality engineering had been applied, to determine whether the principles asserted by Genichi Taguchi were actually being followed. Deviations from Genichi Taguchi's principles were taken as issues confronting internal deployment, and ways of responding to these issues were studied. As a result,two issues became apparent and four root causes and responses were clarified.
