What does R&R mean in ASTRONOMY

Reproducibility and repeatability are measures of accuracy that are used to identify areas for improvement in order to increase accuracy and consistency in test results. Reproducibility refers to measuring the same thing multiple times by different people, while repeatability refers to measuring the same thing multiple times by the same person.

R&R can be used to improve quality control processes so that products meet expected specifications as consistently as possible. It can also be used during production testing, calibration, or any other process where accurate measurements are especially important.

Any type of quality control or production testing that requires accurate measurements could benefit from using R&R. This includes automotive parts inspection, medical device calibration, 3D printing accuracy tests, material strength testing, etc.

The accuracy of measurement results can be measured through various statistical methods such as percent of tolerance or coefficient of variation (CV). These methods allow you to calculate how much variability there is among repeated measurements at different levels or operators.

Improving R&R helps increase product quality by reducing variability between product batches and between items on a single batch. This leads to increased product safety, fewer customer complaints and returns, improved customer satisfaction, and reduced costs associated with reworking defective parts or items.
