Use and knowledge of robust design methodology: a survey of Swedish industry

In this paper, a survey concerning the knowledge and use of robust design methodology in 87 Swedish manufacturing companies is presented. The results show that only 28% of the companies in the study are familiar with robust design methodology, and 17% use the methodology. However, methods that can be useful in robust design methodology are often applied in Swedish industry. The results of the survey also reveal that application of robust design methodology, involvement in a Six Sigma program, QS 9000 certification, and the size of the company seem to be correlated with an increased use of these methods.
