Gage R&R (Gage Repeatability and Reproducibility)

Gage R&R (Gage Repeatability and Reproducibility) is a statistical method used to evaluate a measurement system's accuracy and consistency. It assesses two main components: repeatability examines the variation when the same operator measures the same item multiple times, while reproducibility looks at the variation when different operators measure the same item. By analyzing these factors, Gage R&R helps identify whether measurement errors are due to the measurement tool or the operators, ensuring that processes remain reliable in producing consistent and accurate results. This is crucial in quality control and production environments.
