Dear friends, we are happy to release this video on Process Capability. this is our 93rd video! In this video, Hemant Urdhwareshe, Fellow of ASQ, explains the basic concepts of process capability indices Cp and Cpk with an illustration example. Hemant has also explained how to validate whether the data is normally distributed with histogram and normal probability plotting. Hemant has further explained the interpretation of the results of study and suggested improvement actions.

Friends, I had posted this video earlier. I am posting this revised version to correct some typo errors. Apologise for this!

Thank you Sir for sharing your knowledge and experience for free. Be blessed. 👋

Are your datafiles have the solutions in place?

Dear Sir, I have one doubt...
Actually Cpk is calculated by using the standard deviation (within) but you have shown in the video calculating by using standard deviation (overall). Could you please clarify.. Thanks in advance

Shouldn't Cpk be calculated using sigma estimator instead of standard deviation?
