When Max Hollein joins the Met he will share responsibility for running the institution with Weiss in a new power-sharing arrangement which may prove difficult to manage. Similar arrangements have proved dysfunctional at the Getty and at the Guggenheim, leading to premature departures by high-profile directors who felt interfered with or undermined. The leadership-by-committee model is in stark contrast to the Met’s hierarchy under Campbell and especially his predecessor, Philippe de Montebello, who ran the Met like a semi-divine sovereign.
