No timetable was given for the departure of Wieland, formerly a principal at the Boston Consulting Group.
Van Son was named chief executive of DII at its inception in 2009. The following year Wieland, who has extensive experience in the Middle East, joined DII as director of strategy, with responsibility for formulating group’s long-term rollout plan.
Last year Wieland joined van Son atop DII’s two-person management board, setting in motion the personality clash which led to today’s announcement.
