About Fabien

Comment: based in Lyon (France), mobile in all Europe.

I help global organizations deliver complex business transformations with SAP S/4HANA — from initiation to rollout — on time, on budget, and with measurable results.

As an independent Business & IT Transformation Program Manager, I lead large, international initiatives that align C-suite vision with operational execution.
My focus: building strong collaboration between Business and IT to deliver sustainable change.

With 20+ years of experience across finance, manufacturing, logistics and supply chain, I’ve managed end-to-end SAP programs and global rollouts and complex Cutovers for companies such as GEODIS, Groupe SEB, Vaillant Group and Arkema.
🔹 Expertise: SAP S/4HANA, Program & Rollout Management, Cutover Strategy, Change Leadership, Core Model Design, Data Preparation & Process Harmonization
🔹 Strengths: Driving clarity in complex environments, leading multicultural teams (200+ people), and ensuring smooth go-lives during digital transformation.
🔹 Multilingual: French, English, German

I bring structure, calm, and momentum to transformation and rollout programs — helping organizations turn strategy into results.
