In 2017, a global transformation plan at Capgemini and a need to manage talents differently paved the way for an ambitious leadership development program in France. For the first time, all French business units would be involved in a high-profile training program with a single mission: renewing the managerial culture by developing the interpersonal skills necessary to meet the group’s organizational and people challenges. In 2018, Emlyon Executive Education was selected by Capgemini’s L&D to design and deliver this initiative which became Making Leaders: a 10-month immersive learning journey on the road to Leadership 3.0 whose keywords were “mindset shift”, “culture change” and “personal transformation.” Six years later, Making Leaders has become a trademark at Capgemini France with over 800 alumni from the top leadership tiers of the company, a 6th wave having just started on March 05, 2024; and tangible, lasting change in the teams which can be ascribed to enduring factors of performance: a strong partnership forged at the outset; a shared, deep commitment to the success of an ambitious endeavor (project team, steering committee, sponsors, alumni…); learning innovation blending best-in-class training practices/tools with research-based, proven organizational development methods; and competence in design and delivery.
