Rakuten Institute of Technology (hereinafter referred to as RIT) has a mission to help Rakuten teams with innovation and improve Rakuten products and services using cutting-edge technologies. RIT doesn’t directly collaborate with actual clients, but with long-term partners belonging to the same global company. As a consequence, the success of RIT providing such services, is tied to the level of trust and common understanding between RIT and its partners. In RIT Paris team, we had the intuition that our team could benefit from a holistic study of its operations, using a more user-centric approach than our traditional tech-centric approach. We internally developed skills in fields like UX Design, Design Thinking and Design Sprint, and we put them in practice to test our intuition.
