Can a consortium of 16 organizations, including multinational corporations, local government agencies, and startups, turn a run-down Paris suburb into a "smart" (ecologically viable, high-tech, livable) neighborhood? This case explores how Bouygues Immobilier led such a project involving Alstom, Bouygues Energies & Services, Bouygues Telecom, EDF (Electricity of France), ERDF (Electricity Distribution Grid of France), Microsoft, Schneider Electric, Steria, and Total in Issy-les-Moulineaux (France). The enormous scope and diversity of the project is presented as well as the teaming strategies and governance model that facilitated its success. IssyGrid® earned the "Golden Issy" and "Grand Paris," among other awards, for its innovation and performance.
