Successfully leading and managing - who wouldn't want to be able to do that? Light yet serious, clear yet well-founded, Jürgen Hargens illustrates through systemic insights that leading and managing is an art that can be learned. Theory guides, and this realization is not new, but theory alone is often insufficient. Technique is necessary, yet technique alone is not enough. The interplay of theory and technique, as it becomes evident in the person of the leader, makes it possible. Nothing is more practical than a good theory, Einstein is said to have remarked. Bateson warned against consuming the menu instead of the meal. Tips and tricks, as Jürgen Hargens points out, are welcome, but should not be confused with real life. They are always just guidelines, ideas, and suggestions that only take shape through the actions of the individual.
