This project asks how firms can design and implement effective new business models using digital technology. More specifically, we propose (a) to explore the conceptual foundations of business models in the context of recent developments in the strategic management literature, (b) to analyze the transformation of business models induced by digital technology via a comparative case study approach in two industries, and (c) to identify the key drivers and barriers to economic success in the implementation of innovative business models. Empirically, the project will conduct research on both incumbents and new entrants in health/wellbeing and digital entertainment, two industries that are particularly exposed to digital technology. In bringing together a group of experienced business model researchers from the Université de Lille and from Grenoble Ecole de Management with experts in health/wellbeing and digital entertainment from Telecom Ecole de Management, Institut Mines Telecom - Telecom Bretagne, Université de Grenoble and Inseec, the project aims to build capacity and to increase the international visibility of French business model research. It provides a unique opportunity to train both junior management researchers and future digital technology entrepreneurs (including principal investigators) in business model design, implementation and analysis. Moreover, the project will facilitate the development of longer-term collaborative ties with the participating firms in order to help improve digital technology based business models in practice through the development of actionable knowledge and the creation of platforms for business-model related exchange and learning.
