SPC Can Tell A Story, Though
My good friend, Ernie Huge, co-authored a book entitled Management by Policy. It was published in 1993 by ASQC Quality Press. Page 11 of that book revealed a startling, but not surprising, observation.
As you can see Ford had greater difficulty at process capability than that of Mazda. The wider the dispersion of attributes leads to inconsistent product performance.
Ford management tried to "buy" the knowledge, as well as other Detroit automobile manufacturers. You cannot do this. If you manage, you have to understand. It is a minute-by-minute, day-by-day philosophy. If management thinks they can go from being dogs to world class through an acquisition or some other short-cut, they will lose. Don't buy those companies stocks.
