Introduction to Minitab MSAMinitab MSA is a method to determine the acceptable system of measurement. The abbreviation of MSA in Minitab is measurement system analysis; we are using Minitab MSA for the response of continuous variables. We can also use it to determine the measurement system’s variation. For the response variable of the attribute, we can use MSA to evaluate the appraiser’s accuracy and consistency.

What is Minitab MSA?As we know that any measurement system is very critical for the process of quality improvement. We need to evaluate our measurement before using the capability analysis, charts, and other analyses to prove that our measurement system is accurate and the data is reliable. It includes measurement procedures, devices, and operators affecting the measurement. The result will vary when we measure something repeatedly or use a different process. Variation will come by using two primary sources, a measurement system and the difference between the part we have measured.
We use the variable gage R and R to conduct the Minitab MSA to determine which portion of variability will come from the part and which portion will come from the measurement system. It is a systematic method to analyze and identify the components variation of system measurement as we know that it is mandatory in every six sigma project to ensure that our data is reliable before making any decision. Therefore, it is a checkpoint of data quality before we start any analysis and decide on data.
Below is the example of Minitab MSA as follows:
Regression analysis
Correlation analysis
Analysis of variance
Hypothesis testing
Statistical process control
Design of experiments
The Minitab MSA observed values would be comprised by using two elements as follows:
True value
Measurement error
True value is nothing but what we are trying to determine by using a measurement system. It will reflect true results as part of the process and performance. Measurement error is nothing but the variation introduced by the system of measurement. This contains the inaccuracy of the measurement process. The observed value contains what our system of measurement will tell us. It is nothing but the value of measurement obtained by the measurement system. The observed values represent different measurement types, differentiating into continuous and discrete types.
How to Run an MSA in Minitab?We need to first download and install Minitab in our system to run the MSA. Then, we require the Minitab statistical software application to run Minitab MSA.
In the below example, we have already downloaded and installed the Minitab statistical software application in our system.
Below are steps showing how to run Minitab MSA:
1. Check the Minitab statistical software application is installed in our system.
In the below example, we are checking the installation by opening the software.
Then we need to active the Minitab worksheet. After activating the worksheet, we need to implement gage R & R.
Example of Minitab MSAGiven below are the example of Minitab MSA:
In the above example, we can see that we have created total parts as five, total operators as 3, and total replica set as 3, so our entire run is 45.
After generating the worksheet, we will implement the example of Minitab MSA as follows.
ConclusionWhen we measure something repeatedly or use a different process, the result will vary in measurement. Variation will come by using two primary sources. First, it is a method to determine the acceptable measurement system. The abbreviation of MSA in Minitab is measurement system analysis.
