This is the first time i'm commenting on a math tutorial. I've watched countless ones and yours is simply AMAZING. TOO EASY to understand, with clear english. Keep up the great work! You deserve more
I have been struggling with this unit in my supply chain class, this really helped clear up the idea of Process capability and the difference between the ratio and the index.
Hats off to you sir. This is the most simple and most clear explanation I've come across since learning about SS and process capability. You put everything in perspective for me. I can't thank you enough.
great video Saravanan... I have listening many lectures and videos this long time now only I got the real picture of diff between cp & cpk.. kindly update more videos...
We are talking about 6sigma and you have used 99.73% achievement only. 6 Sigma requires 99.99966% achievement within the design width. Could you please clarify
Great tutorial! Only thing I would add, is that in real world manufacturing you can use Cp to see if your process is capable, even if the mean is shifted. If your Cp is above 1.0, then you know you just need to shift your mean to the center of the design specification and you will have a capable process!
Dear Sir. Lower specification comes from customers (or consumer protection as local regulations and/or laws). Upper specs. comes from producer firm's clear mind. In this case no one wants to buy under 24,5 oz. bottle water and it is not worthing to procuce more than 26,0 oz. bottles, for example.
Until I found this explanation I wasted about an hour to find the right definition of six sigma and realized most of the experts if not all in this subject lacks the mathematical or statistical concept.
I really hate to be the goof of the group but if my professor would have simply stated that the cp was to meet the 'design specification' then it would have made complete sense to me. When I was informed that cp was to measure the processes capability I was thinking that we were answering the question, "what is this process actually capable of if pushed to its max, etc.?" This explanation makes total sense.
Hello Sir, thank you for the video. I have a question? Is there any prerequisite for doing Cp and Cpk. Like the distribution should be normal for doing a Cp.
so when we speak in terms of lean 6sigma, does this refer to 6 sigma on either side of the distribution curve or is this the span of six sigma across the distribution curve?
My question is that in 6 sigma the graph is used of +/- 6 sigma & for Cpk graph is used of +/- 3 sigma as per formula of X axis what is the difference . Please sir answer it.
