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? —Preceding unsigned comment added by 118.168.108.176 (talk) 08:19, 5 January 2009 (UTC)[reply]
