Siobhan McHale has worked across four continents, helping thousands of leaders to create more agile and productive workplaces. She also has been on the “inside” as the executive in charge of culture change in a series of large, multinational organizations. One of these inside jobs was a radical seven-year change initiative at Australia and New Zealand Banking Group Limited (ANZ) Bank that transformed it from the lowest-performing bank in the country into one of the highest-performing and most admired banks in the world. Professor John Kotter used her work with ANZ as a Harvard Business School case study designed to teach MBA students about managing change.
