Talk:Statistical process control/Archives/2009

What is meant by this in the opening paragraph: "SPC is also used to reduce to measure and reduce variation in the process"??? '...used to reduce to measure...'? I can't edit this so that it makes sense as I have no idea what it is trying to say. Perhaps 'SPC is also used to measure...'

Simple: It will show the variables and factors which are being controlables and not controlables. Ludwig E. —Preceding unsigned comment added by 190.166.92.29 (talk) 17:16, 12 June 2008 (UTC)

This stub needs the addition of details of the various charts (e.g. X-bar,R and P-charts).
 * It's a stub no more, so I removed the stub tag. I added a link to control chart which contains all those, although they are red links.  Spalding 14:17, Apr 11, 2005 (UTC)

Wordy, unsourced, no good examples. I'm still not sure how the article even relates to the title.


 * What do statistics have to do with it?
 * What sort of process is being controlled?
 * Is there a thing called "process control"?
 * Who says you can control a process? Or that you can't?

This article stinks. I'd delete it if it was up to me. Uncle Ed 17:14, 20 October 2005 (UTC)

Does this link provide anything other than promotion of a service? There are very short descriptions of statistical process control on this site but the purpose of those descriptions seems to be selling services not educational. Leaders100 12:57, 19 July 2006 (UTC)


 * The editor has spammed it across a few articles. I've removed it as linkspam --AbsolutDan (talk) 13:23, 19 July 2006 (UTC)

Unclear meaning: "significant effect by the Americans"
What does this sentence mean: "Statistical process control was pioneered by Walter A. Shewhart and taken up by W. Edwards Deming with significant effect by the Americans during World War II to improve industrial production."? What does "effect by" someone mean? Which Americans -- all Americans, or those two American scientists, or other American scientists, or American scientists in general, or All Americans, or the United States, or what? Does "with" relate to the "pioneered" ("pioneered with success"), or to "taken up" ("taken up with success"), or what? -Pgan002 22:51, 13 September 2006 (UTC)
