If you don't plan on routinely measuring certain dimensions (Non-critical) during routine production, then a gauge R&R isn't necessary. But for the dimensions that end up on your control plan - where you are going to make routine measurements - you should consider a gauge R&R. You could also work with your friends in Quality to determine the worst case dimension for a gauge R&R, which perhaps would the dimension with the tightest tolerance or the smallest process variation.
Great question - because we collect data all across the business. So it depends on how measurements / data is collected. Do you use a specific measurement instrument or equipment in IT or the financial industry?
Hi Sir, l have a question. Let's say I have 3 operators and 5 parts. Each part measured by the same operator 3 times. The measurements are length measurement and the equipment is a vernier caliper. Should the 5 parts all come from the same part number e.g. Part number 123 or different part number?
Great question. In a perfect world, yes you would want to measure 5 parts that have the same part number. This ensures that they parts are all made using the same process, and fixtured/inspected the same way. If you used different part numbers, and those designs were slightly different, or their production processes were slightly different, or their measurement methods were slightly different, all of that variation would get introduced into your gauge R&R and skew your results in a negative direction.
Hi,very good video. I have question, ia it possible if me as person who will do study also involve as one of appraiser too ? Is because I know the rule so I can make the result of measuring always precision.
No, I would not recommend including yourself in the gauge R&R study. You should pick appraisers who have the same level of skill and training as the people that you expect to use the tool in production. If you include yourself, and you have better precision than most people, then you will be artificially skewing your results, and your reproducibility will not reflect the true long-term variation of that measurement system.
Hi Andy, Comparing these terminologies with your ANOVA video, can we say that reproducibility/operator variance is treatment variance whereas part variance is error variance in ANOVA and as such repeatability/equipment variance explained in this video was not covered in the ANOVA video, right?
Hey Rajesh!! Yes that is correct!!! Great job making the connection between Repeatability and the MSE (error variance). In fact, if you use ANOVA to evaluate the results of your gauge R&R, the repeatability term is equal to the MSE (Mean Square of the Error).
Hi, does anyone know if gage R&R should be performed without informing technicians about it? Point is if technicians are aware of the study they would do it perfectly and gage R&R study might fail.
Hey Tariq, so a blind study (one in which the operators are unaware of the situation, etc) can be helpful if you're worried about possible bias. I wouldn't say it is a requirement though.

amazing job, you made the life of GR&R very easy, but as you promised i am still waiting for the 3rd video
Do you use all the dimensions listed on a drawing or just the SC's on the drawing?

Can you give example and explain how R&R can be used in IT or financial industries?

@@greenbeltacademy noted. Thank you
Thanks a lot for great video! Please advise how the Excel file can be downloaded? Thanks
You're absolutely well!
You can get that excel file here: www.Greenbeltacademy.com/GaugeR&R
Great video. I am looking forward to the new video of this serie!!

Hi Andy, great info! When will the next 2 videos be released?
Thanks! I'm filming that second video this week, and it should be up here in the next few weeks!
What a great video man. Such fine and crisp explanation. Thanks so much.
Thank you!! I appreciate the kind feedback.
Sir that`s a Gold Stuff. Thank you.
You're very welcome
Great video ! can't wait for the part 2 and 3
Thanks - I'm definitely working on part 2 and 3 now!
Awesome vid! when are parts 2 and 3 coming?
Hey Conor!! I think part 2 will come out here in 3-4 weeks!
Excellent breakdown of this topic! Thank you!
