A typical Attribute gage R&R study involves multiple operators, parts, and repeated measurements of the same part by each operator (we call these repeated measurements "trials"). It's common to have 3 Operators, 30 Parts, and 3 Trials on each part. Operators record a simple Pass/Fail (i.e. Attribute) measurement.
