You took a team of machinists through the process of using control charts to determine the Process Capability. You applied the studies to a process that is in statistical control and the output is normally distributed. The specifications for the product processed are 28.0 ± 2.0 mm, while the process mean is 28.6 mm with a standard deviation of 0.53 mm. (a) Is the process capable? (b) If not, what proportion will meet specifications? [8 marks] [8 marks] (c) What adjustment(s) would you make to the process to improve its performance without change its standard deviation? With the adjusted value(s), determine the process capability and comment. [9 marks] You took a team of machinists through the process of using control charts to determine the Process Capability.
