To determine the variation in the measurement system due to the
measurement equipment itself and its use by the appraisers.
When to Use It
Before implementing SPC techniques or conducting designed
experiments to verify that a sound measurement system exists.
Periodically to ensure the measurement system has not degraded.
Important Notes
Most common GR&R Techniques are for non-destructive testing of
variable-data measurement devices. The techniques must be modified
for destructive testing and for attribute-data measurement devices.
