Tiger Tools Inc.
Sample set 1
Is this process in control?
UCL = X-double bar + A2R-bar = 45.156
LCL = X-double bar – A2R-bar = 44.84
N=20 and A2= .18

The process is in control but that doesn’t measure the capability of the process
Rbar= .873, n=20, A2= .18




Standard deviation = 0.234
The specification width is 1.44 cm : The process capability is 1.44 / 6*.234 = 1.03 Since it is less than 1.33


This Process is not Capable
Sample set 2
Why the cycling did not show in the first sample? We think that is it because the sample sizes were too large
Capable

Company:
Tiger Tools, a division of Drillmore Industries.

Problem:
The company planned on launching a new product which required a particular oven

In addition, the company had a freeze on capital expenditures which made acquiring
a replacement oven an unfeasible purchase.
