Understanding Gage R & R allows us to predict the percentage or probability of measurement error and understand the source of the variation (equipment or appraiser).<br> <br> 3.Inference of guage R&R.<br> <br> Less than 10% - the measurement system is acceptable. Between 10% and 30% - the measurement system is acceptable depending on the application, the cost of the measuring device, cost of repair, or other factors. Greater than 30% - the measurement system is unacceptable and should be improved
