R&R is only one key analysis for achieving conclusive and near risk free
measurements of all types.
bias (accuracy)
linearity
compiling all sources of systematic & random errors (also characterized as common and special causes of variation)
ranking those sources by both the most influential and the easiest to improve.
for some instruments there is a long term stability analysis, which helps detect more special cause variations
For measurements that are important to them, your customers want to see a reasonably tight confidence interval (or P/T Ratio) and are often impressed with a report or presentation discussing the MSA (or MCA) for the instruments used to make those key measurements.
Confident Instruments, Inc. can help with performing MSAs on each instrument. We can also perform statistical analysis to determine if grading criteria are set properly given the instrument's performance and customer feedback. On the upstream side, we can assess whether measurements are conclusive enough and at high enough frequency to effectively adjust control production variables and/or predict finished product quality .
