The author presents a "how-to-do-it" guide for developing a mission statement, which demonstrates in a practical manner how mission statements can be collaboratively created within a school faculty. His motto "Involve those affected" serves as the guiding principle that influences the methodological approach in both small and large schools. Step by step, he illustrates how the mission statement can be integrated into everyday school life: effectiveness and commitment are crucial here. Successful examples of guiding principles complete the volume.
