Establishing QC Mean on Multiple Instruments

Should a lab have different QC means for each of its chemistry systems, or one mean for all of them? According to respondents, ideally, each instrument should have its own targets (means), but the use of common targets across identical instruments often comes with a significant practical advantage as long as the instruments are in the same physical lab. However, a common mean will not be suitable unless all instruments are using the same reagent lot and the assay in question has a large sigma value relative to total allowable error.
