The present paper proposes a unified system for monitoring assessor and panel performances based on the MAM. In addition to the product effect (tested at panel and individual levels), scaling and repeatability panel heterogeneities are tested and, when significant, assessors who were responsible for this heterogeneity are identified. Further, the pure disagreement is decomposed over assessors allowing for the individuals significantly responsible for it to be highlighted. Those numerous statistics are summarized into a few diagnostics presented in a synthetic single table called the MAM CAP table.
