What does a Gage R&R study assess in practice?

Gage R&R is all about how much the measurement system itself adds to the data. In practice you look at how much variation comes from the gauge and from the person using it, to judge whether the measurements are reliable enough to distinguish real part differences from noise. By having multiple readings of multiple parts with the same gauge and with different operators, you separate sources of variation into repeatability (same operator, same gauge) and reproducibility (different operators or gauges). This tells you if the tool and the way it’s used are capable of producing consistent, trustworthy measurements within the tolerance. The other options describe factors not captured by Gage R&R: environmental conditions, costs, or time of measurement aren’t the primary focus of this analysis.
