The new edition of this work has not only undergone extensive updates. Rather, it experiences a valuable and interesting expansion through two new contributions. In the second part of the book, which focuses on control models, a new contribution addresses the increasing significance of digitalization. Classic business models are changing, and with them, the requirements for corporate governance are evolving, presenting entrepreneurs with new challenges. The contribution on controlling multichannel business models addresses these challenges and develops solution concepts for the controlling of business models that follow a multichannel strategy.
