assignable causes. Under which of the following circumstances should a QC manager consider this type chart
A. Both1) When the engineering tolerance on a dimension greatly exceeds the natural dispersion of the manufacturing process, and2) When a process is subject to constant but stable tool wear.
B. When a process is subject to constant but stable tool wear.
C. When the engineering tolerance on a dimension greatly exceeds the natural dispersion of the manufacturing process
D. When the number of samples outside the current control chart limits become too costly and
cumbersome to investigate.
E. Both1) When the engineering tolerance on a dimension greatly exceeds the natural dispersion of the manufacturing process, and2) When the number of samples outside the current control. chart limits become too costly and cumbersome to investigate..
i think (E) is more suitable and is the answer
Control charts have two general uses in an improvement project. The most common application is as a tool to monitor process stability and control. A less common, although some might argue more powerful, use of control charts is as an analysis tool. The descriptions below provide an overview of the different types of control charts to help practitioners identify the best chart for any monitoring situation, followed by a description of the method for using control charts for analysis.
Thanks for the invite but I am not able to answer it.
E is close to the right answer
In my opinion
A. Both1) When the engineering tolerance on a dimension greatly exceeds the natural dispersion of the manufacturing process, and2) When a process is subject to constant but stable tool wear
Option A is the correct choice.
E. Both1) When the engineering tolerance on a dimension greatly exceeds the natural dispersion of the manufacturing process, and2) When the number of samples outside the current control. chart limits become too costly and cumbersome to investigate..
Thanks for invitation
Agree Answer Option E
