Dear Technetts,
One of our manufacturing plants is planning to use the ANOVA (analysis of
variation) approach to calculate process capability and repeatability.
I am not really familiar with this method of process monitoring. I've read
on the Internet, that ANOVA allows you to determine significant differences
between two or more means. But, I am not sure how it could be used for high
volume production process monitoring. Is this approach better than X bar
and R charts and process capability histograms?
Does somebody use ANOVA for this purpose? Please, share your experience
with me.
Sincerely,
Stella Neyman
Eaton Incorporation
