This study examines the use of the R&R (Repeatability and Reproducibility) method to improve measurement accuracy in quality control. By analysing single-operator (repeatability) and inter-operator (reproducibility) variability, the R&R method assesses overall system reliability. A case study on automotive part measurements shows acceptable variability levels but highlights repeatability as the main source of inconsistency. To enhance accuracy, the study recommends operator training, standardized procedures, regular calibration, and a stable measurement environment (consistent temperature, humidity, and low vibration). These improvements aim to reduce variability and increase system reliability, ensuring more precise quality control. The findings demonstrate the R&R method’s value in identifying variability sources and guiding measurement process enhancements.References
