Siobhan McHale is an executive and culture change expert. She currently serves as the Executive General Manager of People, Culture & Change at DuluxGroup. McHale has a reputation for fixing toxic corporate cultures, famously leading a radical transformation at ANZ Bank that became a Harvard Business School case study.\n\nShe is the author of The Hive Mind at Work: Harnessing the Power of Group Intelligence to Create Meaningful Change. McHale uses the metaphor of the hive to explain organizational dynamics. She argues that culture is not about "values on a wall" but about the patterns of behavior that happen when people work together. Her work provides a four-step model to identify and shift these patterns, helping leaders mobilize their workforce toward a common goal.
