Talk:Statistical process control

Simple: It will show the variables and factors which are being controlables and not controlables.

This article was nominated for deletion on 2005-10-23. The result of the discussion was keep.

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)[reply]

Keep it...

... and develope it!

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)[reply]

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

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)[reply]

Poor example

Final paragraph:

SPC indicates when an action should be taken in a process, but it also indicates when NO action should be taken. An example is a person who would like to maintain a constant body weight and takes weight measurements weekly. A person who does not understand SPC concepts might start dieting every time his or her weight increased, or eat more every time his or her weight decreased. This type of action could be harmful and possibly generate even more variation in body weight. SPC would account for normal weight variation and better indicate when the person is in fact gaining or losing weight."

fails to illustrate the use of SPC as an indicator of when it's appropriate to take no action. Could this example be improved?
