This book illustrates, through numerous case studies, how leadership and diversity management can succeed in organizations characterized by diversity across various industries and sizes. It provides insights for a better understanding of what diversity can concretely mean today and offers practical examples for the concrete implementation of diversity management in leadership. The foundation is a very broad definition of diversity: Diversity arises from different business areas and the diversity of corporate orientation, leadership requirements across system boundaries, different personalities, and diversity in age, gender, disability, cultural background, etc. The case studies are uniformly structured: specifics of the leadership situation, analysis of the activated emotions and achieved results, lessons learned, and recommendations for practice.
