The margin is higher, the cost of materials less and there is no way to make up the zero-out time of non-production. So it pays off to have the chances of a zero-out at a 6 or 7 sigma level instead of a 3.5 or 4 sigma level (assuming there is a cost associated with having a higher sigma level with greater inventory). <BR/><BR/>You're bathroom is the same. The consequences of having a zero-out on TP could be devistating so for a small extra marginal cost you maintain enough for 100's of cycles.<BR/><BR/><A HREF="http://www.waittimes.blogspot.com/" REL="nofollow">www.waittimes.blogspot.com</A>Ian Furst http://www.waittimes.blogspot.comhttp://www.blogger.com/profile/11795888117578055704noreply@blogger.com
