One of the longest tenures at the top of a major food multinational is set to come to an end, with Irene Rosenfeld, the chairman and CEO of Mondelez International, set to leave the Cadbury and Oreo maker next March. Rosenfeld, who became the CEO of Mondelez forerunner Kraft Foods in 2006, will leave behind a very different business to the one at which she arrived 11 years ago. Dean Best reflects on her time at the helm and outlines what could lie ahead for her successor, the former Coca-Cola, Mars, Danone and McCain Foods executive Dirk Van de Put.
