Dear Anil,
The control chart presentation is good, but you have not acknowledged the sources from where you obtained the information. This is termed as "plagiarizing" in academia. It is also possible that you might have violated copyright laws. For example, I found some of your slides at
7qc Tools 173.
Have a nice day.
