Using another way of interpreting the data set might lead to different results in a particular case. Over time though, no matter which method you use (assuming the method works reasonably well), you would get better at solving many common management problems.<br /><br />Wheeler's approach is a little bit different from what you might find in a Six Sigma or SPC handbook. However, I have found that it works well enough, and it is very simple to use.<br /><br />From a management perspective, the important thing is to calm down and work systematically. It is worth noting that you can get the same results without doing a statistical analysis at all.<br /><br />For example, you can build a qualitative synthetic model in the form of a Current Reality Tree. Random variation would show up as a contributing cause when you use the Categories of Legitimate Reservation.Kallokainhttps://www.blogger.com/profile/15756733532883677794noreply@blogger.comtag:blogger.com,1999:blog-20843954.post-71187667585984721992010-01-20T22:53:04.376+01:002010-01-20T22:53:04.376+01:00Some might wonder how you arrived at the average, ...Some might wonder how you arrived at the average, upper and lower process limits. Because that data is critical to the interpretation of the limited data set provided in the challenge, can you comment on how you derived those limits?Randyhttps://www.blogger.com/profile/08652860345792687947noreply@blogger.com
