About Marie

I intervene during moments of transformation — when the organization is in motion, strategic stakes are being reshaped, and teams need a clear direction.

In these pivotal moments — reorganizations, cultural transformations, growth accelerations, or loss of meaning — I support leaders and teams in regaining clarity, responsibility, and a shared path.

With over 20 years of experience in organizational strategy and transformation — in industry, services, and the public sector — I have forged a conviction:
the quality of a transformation depends above all on the governance's ability to assume its role, clarify responsibilities, and hold the course in sensitive times.
This is why I favor demanding and deeply collective approaches, which connect strategic vision, operational realities, and human dynamics.

What I bring:
a strategic perspective, the ability to build bridges between stakeholders, and a method to empower everyone to take responsibility for their organization's challenges.

What I do:
I help organizations free themselves from what holds them back to dare what awaits them.

Experience

  • Hadès -Archéologie préventive
    Consulting in Managerial Transformation / Innovation
    ARCHITECTURE AND URBAN PLANNING
    June 2025 - Today (1 year and 2 months)
    Toulouse, France
    Hades wanted to reflect on the role and posture of its managers. My mission aims to:

    • Evaluate the existing managerial posture, taking into account Hades' specific culture and DNA, to understand strengths and areas of tension.
    • Support managers in their evolution through collective and individual approaches, fostering awareness and adoption of new practices.
    • Understand the company's cultural specificities to build a tailor-made approach, respectful of its identity while introducing necessary disruptions.
    • Structure and lead experiential workshops to work on key postures: trust vs. control, accountability, cross-functional cooperation, inspiring leadership.
    The approach is tailor-made, cultural, and empowering: it builds on Hades' history and identity while proposing experiments that allow managers to embody a new posture, in line with future challenges.

  • CNES
    Consulting in Organizational Transformation
    AVIATION AND AEROSPACE
    April 2025 - Today (1 year and 4 months)
    Toulouse, France
    As part of **the modernization of its organization**, CNES initiated a **strategic review of the evolution of its Human Resources function**.
    The "added value" is the shared desire of the teams to decenter practices and introduce disruptions to accelerate transformation.
    My mission is part of this objective and consists of:

    • Assisting and advising the head of HR transformation topics.
    • **Introducing a deliberate "cultural shock"**: breaking with certain established habits and ways of working to bring new ways of thinking about the HR function, the managerial role, the relationship to work, and the impact of AI. This disruption serves as a trigger to open up possibilities and create the conditions for real change.
    *Providing an external and structuring perspective on the challengesof the HR function, by identifying priority transformation areas to meet the current and future needs of the establishment.
    • Leading acollaborative processinvolving HR stakeholders and parties concerned, to foster buy-in around necessary changes.
    • Structuring and leading workshops tomap key issuesand define operational and strategic improvement levers.
    • Equipping the HR department witha clear vision of the projects to launch, prioritized by transformation stakes.
    • Supporting the transition to action by proposing a pragmatic roadmap and monitoring indicators to track progress and measure impacts.
    The approach is based on **empowerment and co-construction**: it is not about delivering a "turnkey" solution, but about enabling CNES to become the driver of its own HR transformation. The goal is not only to improve the existing situation but to enable CNES to adopt a new HR culture, in line with future challenges.
