CHAPTER 9: PROCESS CONTROL AND CAPABILITY

What process targets (in terms of mean and standard deviation of the filling process) are needed for the filling machine to have a six-( capability? Answer: We need to center the process at the middle of the specs, i.e., at 400 gms. To yield six sigma quality the standard deviation must be (400-390)/6 = 1.67 gms. 88 Chapter 9.
