How are business models purposeful designed and structured? How can the models be implemented professionally and managed successfully and sustainably? In what ways can existing business models be adapted to the constantly changing conditions? In this clearly structured reference work, Bernd W. Wirtz gives an answer to all these issues and provides the reader with helpful guidance. Although, Business Model Management is first and foremost a scientific reference book, which comprehensively addresses the theory of business models, with his book Bernd W. Wirtz also turns to practitioners. Not least, the many clearly analyzed case studies of companies in different industries contribute to this practical relevance. My conclusion: Business Model Management is an informative and worthwhile read, both for students of business administration as a textbook as well as for experienced strategists and decision makers in the company as a fact-rich, practical compendium.

Numerous examples from business practice highlight the importance of business models in the context of strategic management.

Due to changing conditions, the executive board ofa company is confronted with growing challenges and increasing uncertainty. Thus, a holistic understanding of the corporate production and performance systems is becoming more and more important. At this point, Bernd W. Wirtz introduces and presents the concept of the structured discussion of the own business model. Business models present operational service processes in aggregated form. This holistic approach channels the attention of management, supports a sound understanding of relationships and facilitates the adaption of the business to changing conditions. The management of business models is thus an integrated management concept. Through the conceptual presentation of complex issues the author makes a valuable contribution to the current literature. In particular, the referenced case studies from various industries make the book clear and very applicable to practice.
