    can somebody tell me if six sigma is suitable for a mint especially in manufacturing banknotes?

    Yes, it is. Six Sigma elimates variation and defects.

    Hicham – if you have people and machines doing things then SS can help. So, yes it can help.

      As an aside, If you want to get some idea of the kinds of production errors that can occur go over to one of the currency auction house web sites or over on e-bay and look under the category “error notes” or “errors”. 
      The combination of QC and multiple inspections keeps most of these out of circulation. I don’t know if the Bureau of Printing and Engraving has tried anything other than this for defect minimization but I do have the impression that errors in later revisons of the U.S. notes show up with far less regularity than with notes whose revisions were in the 1970’s and 1980’s.  (Notes, unlike coins, are not dated on a yearly basis – the date will refer to the first time that particular design was put in production.  Subsequent small changes will be noted with a letter designation following the year.  At some point someone will decide there have been enough small changes so the next revision will have a new year date… and then the process will repeat itself.)

    The Denver mint is very non-lean and as such could certainly be more profitable.
    In the printing world you’re lucky if quality levels exceed 4.5 sigma so I’m really not supprised that some currency makes it to the e-bay’s of the world. 
    In improving the printing industry there is a subtle blend of Lean and Six Sigma tools (some advanced) to drive improvements.  It’s unfortunate that the print houses I’ve worked with have shops that look like they came from the 1960’s through the 1980’s – there is a lot of room to take them to world class.
