Why Did Shewhart Place a Premium on Time Order Sequence?Avoid the unnecessary waste of being misled
Wed, 12/05/2018 - 12:03
Walter Shewhart, father of statistical process control and creator of the control chart, put a premium on the time order sequence of data. Since many statistics and graphs are unaffected by this, you might wonder what the fuss is about. Read on to…
Making Sense of Data: How to Go About It?To make sense of any data set, start an analysis with a process behavior chart
Thu, 06/28/2018 - 12:03
I recently got hold of the set of data shown in figure 1. What can be done to analyze and make sense of these 65 data values is the theme of this article. Read on to see what is exceptional about these data, not only statistically speaking.…
Sustaining Predictable and Economic Operation: What Does It Take?Entropy will make each and every process unpredictable
Mon, 11/06/2017 - 12:03
In theory, a production process is always predictable. In practice, however, predictable operation is an achievement that has to be sustained, which is easier said than done. Predictable operation means that the process is doing the best that it…
