The chapter offers a broad review of the literature at the nexus between Business Models and innovation studies, and examines the notion of Business Model Innovation in three different situations: Business Model Design in newly formed organizations, Business Model Reconfiguration in incumbent firms, and Business Model Innovation in the broad context of sustainability. Tools and perspectives to make sense of Business Models and support managers and entrepreneurs in dealing with Business Model Innovation are reviewed and organized around a synthesizing meta-framework. The framework elucidates the nature of the complementarities across various perspectives. Finally, the use of business model-related ideas in practice is discussed, and critical managerial challenges as they relate to Business Model Innovation and managing business models are identified and examined.
