There is a method for controlling variation that has been in use since the 1920's. It has produced remarkable results. The United States occupation forces taught the method to the Japanese in the ‘40s, and it became almost a religion to many of the industries there. In a matter of 20 years, it turned Japanese output from toys and trinkets to top-of-the-line products. The technique, in large part, is what makes a Lexus a Lexus, and a Nikon a Nikon.
I have been using Statistical Process Control (SPC) to control industrial process since 1980. Its basic tool is the control chart; simple in concept, but somewhat complicated in its application.
I have had Type II diabetes for a number of years, and have tried various control techniques with indifferent results. A few months ago, I tried putting the information I was already keeping on a control chart. Within a month I had a process that was both stable (predictable) and within the limits of variation my doctor recommended (on spec). I have since applied the technique to data provided by other diabetics, with similar results.
An additional benefit includes the fact that by varying my diet one item at a time, I can test my tolerance to specific foods. This feature has allowed me to expand my diet considerably and tell me what foods I absolutely must avoid (some of which are allowed on most diabetic diets).
My own chart is presented as an example here. I won't attempt to explain how it works unless you want to experiment with the technique yourself. The principal value of the technique lies it its ability to establish control limits of the process as if it were in control, even when it is not. It therefore tells the user what his or her present control system is capable of. It is the only technique which allows this kind of analysis, and holds the secret used to accomplish so many things in industrial applications.
The most amazing feature of the control chart, however, is that it can warn of instability well before the doctor's desired limits are breached!
