These are the comments of the previous paper.

Unfortunately, it appears that there was a misunderstanding of the assignment.

You gave a simple statistical analysis of some data but you did not create an SPC (emphasis on the Control) analysis.

In reality you would need to find data that demonstrates say a manufacturing run over time that shows you that the parameters vary over time. You would then most likely create X-Bar and R charts and calculate the mean and the upper and lower control limits that the process needs to stay within.

These charts are used to monitor and control the process. The information you gave is descriptive and it does not give you the means to feed back into the system to keep it under control.

Also, you were asked to give specific recommendations for improvement and instead your discussion was general and you talked around the issue instead of being specific.
