This presentation is the fruit of labour of five people, working for two weeks on a fictive call for tenders for the renown Château de Versailles. The main challenge consisted in turning the website into a real experience while preserving the Versailles' excellency, its History, and all the necessary informations to get there. Our value proposition was to guide and accompany the user from the choice of its reservation to the physic visit. We intended to find new solutions to make the consumer feel safer, more trustful and tickle its curiosity. Hope you enjoy. The presentation is in French.
