The author describes how sustainable corporate and employee leadership can look beyond hierarchies today. Her thesis: Hierarchies as a fundamental principle of organization and leadership have long become outdated and must be replaced by new forms of collaboration. The book answers the following questions: - What future-oriented and competitive organizational and leadership model replaces the traditional hierarchy principle, and how does it work? - What processes do traditionally structured companies undergo in their transformation towards a hierarchy-free organization, and how can this change process be specifically influenced? - What characteristics define hierarchy-free employee leadership? - What framework conditions need to be considered?.
