Excellent video, Thank you for sharing. I have one question. Help me, to explain raw data to Minitab. How run data is converted to part data, I always have issues here.
I appreciate your viewpoint, but following the sequential process in learning is critical. If you are directly jump to last video, you are missing many concepts. For more detailed learning, please visit vijaysabale.co/msacourse
Higher the NDC, greater will be the capability of your measurement system to detect smaller differences. Yes, you can say 4 is good. NDC indicates the capability of your measurement system to divide the total observations into number of group based on their similarities. AIAG indicate it must be 5 or more, but depending on criticality of your measurements, you can select the most appropriate one.
Thank you for the informations. I have a question, if we do not know the "upper spec-Lower spec" for these samples , (if there is no standards,or customer spects) How should we do? Do we calculate the tolerances and enter the these calculated tolerances ourselves?
That's a practical question. In this situation, you can either use the tolerances specified by your internal team, design team, or product development team.
Hi Sir, Good Morning I have done the GR&R study at my tester ,but i always getting %Study Var value are more than 30% but The %tolerance is acceptable. Also NDC always getting 1 only may i know what is the actual causing i fail the study . Kindly advice..
Thank you for your valuable comments. Good morning. As you are getting NDC as 1, you need to change the measuring device to more precise one. Currently, your measurement device is not able to separate the parts.
Thank you for your great video. What is relevant for deciding which method ANOVA vs. X bar & R in minitab to choose? Or is it all the same which method you choose! I can't go wrong?
Thank you so much for your valuable comments! ANOVA method is more accurate than the Xbar-R method due to the additional element of Operator by part interaction.
Sir plz explain how to select samples for msa study. If Dimn is 10.0 +/- 0.02 can i take sample outside from this limit like 10.03 or 9.97 for study. Plz explain sir
Thnak you for the vidio. Which MSA should I use if the measuring in process? That means there are not 2 or 3 operators, just one mesuring device and 10 parts to be measure 2 or 3 times.
Thank you for your valuable comments and appreciation 🙏☺ Still, you have to use the Gage R&R study crossed. Although the reproducibility part is not there, you are measuring 10 different parts. If there is only one part with one operator, then you can go for a Type-1 gage study.
Where does Process tolerance =8 come from? I think you just copied the value that Minitab uses on their website. Can you please elaborate more on the process tolerance number used with an example? Thank you
Hi Prashan, Thank you for your valuable comments. This process tolerance value is from the previous example that we have continued in this exercise. Yes, this example is from Minitab, so you can say that. The process tolerance value is the standard by which the capability of your process is determined. It is generally a 6*standard deviation in your process. Please reply to me if need further clarification.
@@learnandapply : Yes I would like further clarification since your video does not explain that number and just copied what Minitab website had. I don't think you can calculate process tolerance using standard deviation. Process tolerance value comes from the drawing requirement as desired by the customer. Is the the specification range.
I am not sure whether you read my earlier comment. It's from the previous example. If you calculate the standard deviation and multiply it by 6, you will get the process tolerance. Here, why 6 - because we are targeting Cp as 2. If you want to target Cp as 1.67, you can also consider process tolerance as a 5*standard deviation. You can also keep that blank if you have concerns about where it came from, or calculate process tolerance for the data using a formula. It's alright.
What is the difference between %Contribution and %study variation ??? Both are telling us the amount of variation that can attribute to the factors? is that correct ??
Yes, but the contribution method talks about the % contribution of GRR in total variation, whereas in % Study variation 6*std dev to see the % of GRR in total variation.
The purpose is different. The % contribution is used to assess the variation for each source of measurement error. Whereas, if you use the measurement system to evaluate process improvements, such as reducing part-to-part variation, %Study Var is a better estimate of measurement precision. If you want to evaluate the capability of the measurement system to evaluate parts compared to specification, %Tolerance is the appropriate metric.
@@learnandapply by the way, you're English is very good! As a Russian speaker I've understood you clearly without any confusion. Keep up the good videos!
I understand that if P values for operators and for parts are 0 in this example we accept the null Hypothesis. Which means we need to evaluate ore Measurement System. Did understand correctly?
If p values are less than the significance level (generally 0.05 for 95% confidence interval), we reject the null hypothesis. And we need to evaluate our measurement system.
Excellent video. Thank you for the concise explanation!
Thank you so much for your valuable comments. Please share your friends and colleagues.
Great video, thank you!
Glad you liked it! Thank you so much for your valuable comments and appreciation 🙏😊
I only have 3 sample size, can I get an accurate GR&R result using minitab???
It's not meeting the data requirements.
So, the results may not be reliable.

Gage R and R less than 10% acceptable,
10-30% requires caution,
More than 30% unacceptable

If NDC is = 4 or greater, should that be ok too? Not sure why you jumped from 3 to 5 being acceptable.
Higher the NDC, greater will be the capability of your measurement system to detect smaller differences. Yes, you can say 4 is good.
NDC indicates the capability of your measurement system to divide the total observations into number of group based on their similarities.
AIAG indicate it must be 5 or more, but depending on criticality of your measurements, you can select the most appropriate one.
Very informative and an excellent video. Please answer why do we put for Upper spec - Lower Spec =8 in minitab?
Thank you for your valuable comments and appreciation! 🙏😊
The tolerance mentioned in the example was 8 microns. So, it was inserted there.
Thank you for the informations. I have a question, if we do not know the "upper spec-Lower spec" for these samples , (if there is no standards,or customer spects)
How should we do? Do we calculate the tolerances and enter the these calculated tolerances ourselves?

Hi Sir,
Good Morning
I have done the GR&R study at my tester ,but i always getting %Study Var value are more than 30% but The %tolerance is acceptable.
Also NDC always getting 1 only may i know what is the actual causing i fail the study .
Kindly advice..
Thank you for your valuable comments.
Good morning.
As you are getting NDC as 1, you need to change the measuring device to more precise one.
Currently, your measurement device is not able to separate the parts.
do you mean the device value need to make sure precise one?
Please change the measuring device with a other one having least count less than current one.
Hello Sir,

Thank you for your great video. What is relevant for deciding which method ANOVA vs. X bar & R in minitab to choose? Or is it all the same which method you choose! I can't go wrong?
Thank you so much for your valuable comments!
ANOVA method is more accurate than the Xbar-R method due to the additional element of Operator by part interaction.
Thank you for the video. What is best Minitab or JMP (SAS)?
As I am using Minitab only, I can comment about the Minitab. It is the best and most effective statistical software.
Sir plz explain how to select samples for msa study. If Dimn is 10.0 +/- 0.02 can i take sample outside from this limit like 10.03 or 9.97 for study.
Plz explain sir

I understand that if P values for operators and for parts are 0 in this example we accept the null Hypothesis. Which means we need to evaluate ore Measurement System.
Did understand correctly?
If p values are less than the significance level (generally 0.05 for 95% confidence interval), we reject the null hypothesis.
And we need to evaluate our measurement system.
Very Intuitive, Thank you for putting this together!
