Presenting a broad literature review of scholarly work in the area of Business Model Innovation, this new book analyses 50 management theories in the context of BMI to yield valuable new insights. Research on BMI is still in its infancy and has so far proved to be more than just a sub-discipline of strategy or innovation research. Exploring the field of Business Innovation demonstrates the importance of the discipline as a more specialized management research field and offers new understandings of this important subject. It presents 'grand theories' that will help researchers approach BMI through a different angle and describes business models as phenomena, enabling readers to understand their patterns and mechanisms. Reviewing the most important academic work on the subject over the last 15 years, the authors aim to open up the debate and inspire researchers to look at this phenomenon from new and different angles.
