As a department of the Metropolis of Lyon, Erasme contributes, through its methodologies and actions, to the territory's public and digital innovation policy. Our mission is to respond to societal issues and new challenges to our public policies by proposing concrete ideas that can be tested in a short period of time to respond to the territory's problems. Our approach combines frugality and agility and favors prototyping and participatory design to build an inclusive, learning and sustainable metropolis. The UrbanLab is a place dedicated to the ideation, prototyping and experimentation of digital solutions applied to the public policies of the Metropolis of Lyon. This is where the methods, innovation workshops, incubation and support implemented by Erasme are implemented.
