Schools have to cope with numerous challenges and changes. How can the organization of school succeed in the area of tension between individualization and standardization? What does leadership mean? How can changes be shaped together? In order to be able to work together as a community and as an organization, two overarching topics must be considered: "Leadership and Cooperation in School and Teaching" and "Organization and Organizational Development". Holger Lindemann addresses these topics in the two volumes of "Unternehmen Schule". School is understood here as an organization, which is to be arranged actively by the persons involved. The two volumes provide a clear and practice-oriented introduction to organizational theory and management models. Work aids and exercises make the models manageable for practice.
