Interdisciplinary Success "Interdisciplinary Competencies" play a significant role. These terms are used with great familiarity in scientific, educational policy, and public debates. But do all parties understand the same thing by them? What are the potentials, and where do the pitfalls of interdisciplinary approaches lie? The author comprehensively analyzes interdisciplinary competencies in their theoretical, empirical, and practical forms. The introduction not only provides an overview of the complexity of the topic but also serves as an important working basis for one's own actions in science and practice.
