On behalf of RATP, we created a signage charter for offices and workshops. Much more than a simple signage charter, the aim was to introduce a principle that would make the flexibility of workplaces usable, and play a full part in the company's internal communication. The meticulous design, the choice of vocabulary in reference to know-how and trades, and the thoughtfulness with which the themes are approached all contribute to a better understanding of spaces and new uses in a company where social dialogue is paramount.

And in a place that could have remained dedicated to functionality and engineering, we were able to bring in the cultural and heritage history of this company whose roots go back more than a hundred years.
