Assignment:
You're managing an aluminum coating process and the specifications call for 25 +/- .3 grams of anodizing coating for each fabricated component. A sample of 50 components were drawn with the coating results, in grams, shown below. Too much coating is as detrimental to the project as too little and you've calculated that it costs $60.00 to scrap a defective coating. The results below

a. What is the value of K in the Taguchi Loss function?
b. What is the expected loss, per unit, of this sample?
c. On a separate sheet of paper (MS Word document), briefly (one page, double spaced) describe how the Tagushi Loss Theorem supports the primary goal of Deming's Quality Philosophy.
(this philosophy was consistent with Joseph Juran, Phillip Crosby and other quality practitioners)
