Measurement error is unavoidable. There will always be some measurement variation that is due to the measurement system itself. However, such measurement systems are seen throughout industries. One example is quality control inspectors using a high-powered microscope to determine whether a pair of contact lens is defect free. Hence, it is important to quantify how well such measurement systems are working. Repeatability means that the same operator, measuring the same thing, using the same gage, app to download music to sd card get the same reading every time. Reproducibility means that different operators, measuring the same thing, using the same gage, should get the same reading every time.

  • Step 5 : Now you have the results of both the trails for each operator for all 10 parts. Include the standard or accurate response in the last column. You get this standard or accurate response through your customer or your most experienced subject matter expert.

    You can use any statistical analysis software, or an MSA macro enabled template that you can easily download from the internet, to do the test. I free use MiniTab, one of the minitsb statistical analysis software for Lean Six Sigma practitioners. You need to structure the the data in a specific format to use it in MiniTab.

    You need download put this whole data downlozd 4 columns. The first column is for Part numbers, second for Operator names and third for results. The fourth column should have the standard values for each part. It will look similar to the image below. Copy this data set into Minitab worksheet.

    The path for this test in MiniTab is as shown below —. In the command box, you see 4 fields to free inputs to MiniTab. These are minitab inputs that MiniTab will use to analyze the data that you have collected and minitab you the results. This download to the column where you have the Acceptability results stored.

    This is your Results column. To provide the input, click on the text box in front of Attribute Column. All the eligible column names will appear in the white box on left hand side of the command box.

    It will appear in the text box next to Attribute Column. Illustration below.

    Making Sense of Attribute Gage R&R Calculations

    You get MiniTab test results in 2 forms, a textual output and a graphical output. Below are both the results. Do not get confused or overwhelmed by so many numbers and statistics thrown at you by MiniTab. What you need to check in these results is the Percent Agreements.

    Key Assumptions

    In such cases you conclude that you have the right measurement system in place and proceed with your data collection. Let us look at each of these parameters. The first block in the text output talks about Within Appraiser agreement assessment. This is a comparison of the results of each trial of a single operator and shows if the operators are able to repeat their own results across multiple trials.

    This is called Repeatability. As you can see in the below results, Appraiser A and B repeats his results for 9 out of 10 parts across trials. This means, your measurement system does not have Repeatability issues.

    In such cases, we will need to further coach the appraiser on correctly assessing the parts for Acceptability and redo the MSA. This is Accuracy of the Measurement System. Appraiser C, however, provides the same response as the Standard for all 10 parts across all trails.

    This is the comparison of results of each part across all operators and all trials. Ideally, all appraisers should give the same results for each part across all trials. This is called Reproducibility. Related Post : What are the measures of Variation? As you can see, out of 10 parts, dowbload the appraisers were able to match the results only for 8 parts in all the trials.

    We have Reproducibility problem in our Measurement System. This needs to be corrected before we can use this measurement system to collect data. The previous comparison was between each appraiser vs standard whereas this test compares the result of all appraiser collectively downlowd the standard. That means, it will show a particular part as matched only when all appraisers across all trails give the same result for the part as the standard.

    Or the MSA failed.

    Sep 28,  · SPSS is a professional commercial-grade software suite for statistical analysis of data. Initially designed for social science research, over the years the suite developed into one of the most recognized analytical tools in higher education, business, and scientific worlds.

Nevertheless, Minitab has a module called Attribute Agreement Analysis (in Minitab 13, it was called Attribute Gage R&R) that does the same and much more, and this makes analysts’ lives easier. Having said that, it is important for analysts to understand what the statistical software is doing to make good sense of the report.

    What do we do in such cases? Well, is quite simple and obvious. At the highest level, there are just 2 reasons why the MSA can fail. Either the equipment used is not correctly calibrated or the operators are not able to read the equipment correctly and precisely. The eBook contains a comprehensive list of more than acronyms and abbreviations relevant for Lean Six Sigma.

    What you need to do is further refine the operation definition of the said attribute in this case, Acceptability of the wooden plank and make is more robust for everyone to understand.

Nov 05,  · I will use MiniTab, one of the preferred statistical analysis software for Lean Six Sigma practitioners. However, the results and the takeaways will stay the same irrespective of what software / template you use. You need to structure the the data in a specific format to use it in MiniTab. You need to put this whole data into 4 columns. Nevertheless, Minitab has a module called Attribute Agreement Analysis (in Minitab 13, it was called Attribute Gage R&R) that does the same and much more, and this makes analysts’ lives easier. Having said that, it is important for analysts to understand what the statistical software is doing to make good sense of the report.

    The jinitab should be crystal clear leaving no doubt about the metric in the operators mind. Next, coach the operators. Ensure that they all are on the same page with regards to the attribute, what is acceptable, what is not. Once this is done, repeat the whole MSA again and check the agreement percentage.
