→ MSA is very famous in an automobile domain.

→ This study helps us to identify about the capability of the appraiser and measuring instrument.

→ In very simple way we can say that this study is very useful to determine the accuracy of the measurement system.

→ Measurement system is the combination of the measuring instrument and the appraiser.

→ Appraiser is the person who perform the GRR study.

→ GRR Study is the standard method within the manufacturing sector.

→ Also, You can check here, Different Six Sigma Project Templates Download

Example of the GRR Study with Excel Template

→ Refer to the below example of the GRR study.

→ In this example we have taken 3 appraiser and the 10 parts.

→ Each appraiser will perform the 3 times measurement for all 10 parts in ascending, descending, and random order.

 → For detailed rules for performing GRR Study refers to the AIAG MSA Manual.

→ This template is very easy to use and very impressive and editable.

→ Also, very attractive graphs are also added into this template.

→ This template contains multiple excel worksheets and navigation links are provided to all pages to navigate between all work sheets.
