A lithography system in which a performance criterion of the lithography system is predicted, based on one or more operating conditions of the lithography system, and compared to measurements of that performance criterion. The lithography system may determine from a difference between the measured and predicted performance criterion which, if any, sub-system of the lithography system is not performing as expected.
