During the presentation I propose to first present the way we monitor customer satisfaction and how we take benefit of the gathered feedbacks to tackle and prevent our customer concerns. Actionable insights lead to improvement in procedure and processes but also lead to innovative and transformation projects... Reversely, innovation as such, if used appropriately, can also bring inspiration to improve customer experience, on-line or in stores. Finally I propose to conclude by presenting the Growth Hacking methodology we recently introduced in our marketing department that allows us to experiment new concepts and innovation in an agile and rationale way.
