In this essential work, Marco Furtner outlines the fundamentals of visionary and charismatic influence in leadership (Is charisma innate or trainable?). The author provides a clear overview of the effectiveness of transformational leadership, which has revolutionized leadership research: over the past 30 years, no other leadership approach has been studied and discussed as frequently. The central reason for this is that transformational leadership represents an idealized form of leadership and leverages the "shine" of charismatic influence. It is all the more surprising that a search for German-language books on the title "Transformational Leadership" has so far yielded only student theses.
