Successful diversity management requires HR managers to possess skills in leadership, organisational development, change management, psychology, communication, measurement, and assessment. Such cross-cutting skills might seem broadly useful to the success of any business initiative. However, there is a key difference with diversity management. For organisations to profit from diversity, the people in those organisations must change how they interact. Diversity's focus on changing human processes requires and defines HR's role in diversity management (Kreitz, 2007).
