Based on empirical studies, this book presents theoretical insights into change communication for practical application in businesses. Competent communication is essential for the successful implementation of change processes within companies. In this context, the authors analyze speeches from the political arena, with the expectation that these analyses will provide new insights for crafting speeches to professionally support change processes in business enterprises. The foundation of this analysis includes speeches by US President Barack Obama during his first election campaign, his first term in office, and his campaign for re-election. This represents an innovative interdisciplinary approach to the topic of communication in change processes.
