Although there is an increase in women in leadership positions, women still only represent a fraction of the leaders (Catalyst, Women in the workforce – global: Quick Take. https://www.catalyst.org/research/women-in-the-workforce-global/, 2021). This chapter focuses on three factors that are crucial for successful leadership careers—(1) wanting (e.g., leadership motivation), (2) being able (e.g., leadership competence), and (3) being allowed (e.g., organizational conditions)—and shows how female (junior) leaders can be specifically promoted. At the center of this chapter are current practical approaches that particularly emphasize these success factors: (1) FÜMO-Coaching addresses, among other things, the “motivation brakes” in leadership motivation (wanting). (2) The stumbling block training addresses the practical handling of potential career hurdles for women (being able). (3) The training to reduce implicit prejudices strengthens both the perception of women as potential leaders and leadership competencies. (4) On a structural level, flexible working models such as shared leadership enable a better balance between work and family (being allowed). For all approaches, concrete action measures are given that support successful implementation. A possible integration of the female junior promotion into personnel development is finally illustrated using the example of the Otto Group.
