Measurement System Analysis

(MSA)

MSA

Measurement system analysis is a statistical study. It determines how much variation the measurement system is contributing to the total process variation. The study also tells us how much gage error is in the measurements we get from measuring a product.

Gage R & R

Repeatability and reproducibility are two of the variations that contribute to gage error. They measure the amount of variation from the gage operator and from the gage itself. However, bias, stability and linearity also play a part.

Bias

Bias is the difference between the observed average of gage readings and an accepted average obtained from a higher-level instrument.

Linearity

Linearity is the bias throughout complete operating range of the gage. All gages have bias and we want that bias to be linear. This allows us to know what the bias is at any point in the gages range.

Stability

Stability is how long the gage can maintain its acceptable operating status under normal conditions of use. The stability factor gives us a yardstick for determining how often a gage needs to be checked and possibly calibrated.

Course content

Learn how to conduct gage studies and determine the extent of variation that the gage contributes to your company's process variation.

This is a "hands on" class not a management overview.  Students will conduct workshops and perform various calculations for gage studies. Students should bring a statistical calculator. Loaners will be available.

The Measurement System Analysis class uses the reference guide published by AIAG for the automotive market. However, the techniques apply to any and all gages and industries.
