As I am given to understand, a GR&R is internal, whether you have 1 or 100 people and 1 or 100 machines.....
However, Round Robin, aka inter-laboratory comparison (ILC) or proficiency test (PT), is between different organizations.....it needs to be noted that PT/ILC may often have a level of rigor not normally considered to be associated with Round Robins, to include a report detailing Z-Score (test) or En Score (calibration).....
