Professional users and potential clients will find here an approach that goes far beyond individual cases. The structure of this unusual book is based on cases, and for each case, there are several modules: case presentation, comments on the case, what can be generalized from the individual case? What focus can be chosen for this case, what is its specificity? Theoretical foundations related to the individual case, maxims of professional action concerning the focus of the case, follow-up from the case presenter: What actually happened? Evaluation of the comments from today's perspective. With an introduction by "coaching pope" Wolfgang Looss and a greeting from Peter Hartz.
