These tools deal cautiously with employees, clients and cooperation partners in order to ensure sustainable success of an organization.In the final chapters the authors delve into specific attitudes during the change process, such as the building of trust and the allowing of emotions. Several cases illustrate how the concept and the tools promote organizational development. The book well provides a practical guideline.Additionally, the book talks about important aspects managers have to pay attention to, such as dealing with concerns and resistance. The values of the systemic concept like sustainability, selective participation and growth from inside are convincingly exemplified.The book is theoretically sound and grounded by the authors‘ long management and consulting experience and their research activities with the university background.
