Since someone mentioned ISO9000 in SBIs other thread it might be important to point out I doubt any measuring tool from Harbor Freight comes with an ISO9000 compliant calibration document. Calibration costs more than most of these do new. (I used to be the I9K guy)
I do believe that in a large percentage of the country we abandoned ISO9000 and "six sigma" quality programs years ago.
I know IBM handed out "Market Driven Quality" hats at a meeting (along with the M&M presentation) and we never heard about "six sigma" again. We stopped chasing Sony and fell in behind Sam Walton.
