I am looking for the proper term that would describe the Failure Rate of expected packages within a manufacturing process? For instance, out of 1 million packages, I can expect 10 packages to be bad.


I am not sure if its a Six Sigma method.


Any help would be greatly appreciated.

Hi mec862


most companies measure the rate of non-conforming products by setting for customer complaints.  5 customer complaint for one million packs gives you 99 percent in specification products.

Terms used include Acceptable Defect Level or Acceptable Quality Level


I don't get the previous post regarding complaint levels (5/1,000,000 = 0.0005%), for one you are not guaranteed to get a complaint for every defect although monitoring complaint levels and measuring complaints per million units is a good idea. See the article I wrote Using Trend Analysis to Reduce Complaint levels


Kind regards,
