About Gaël

HEI engineer and APICS CSCP certified, I support industrial companies in improving their operational performance, managing their inventory, and transforming their Supply Chain.

With over 20 years of experience in Supply Chain, gained in demanding industrial and distribution environments, I focus on issues related to flows, planning, forecasting, inventory management, and continuous improvement.

My career has been notably marked by an experience at Toyota, where I developed a strong Lean culture, based on field observation, problem-solving, process standardization, and continuous improvement. This experience is now a differentiating asset in supporting industrial companies with their performance, reliability, and transformation challenges.

I primarily work on:
• Industrial Supply Chain Diagnostics
• Inventory Reduction and Service Level Improvement
• Flow Management and Procurement Optimization
• S&OP / MPS
• DDMRP and Buffer Management
• Operational Excellence and Lean
• Process Structuring and Standards
• Team Support and Change Management

My approach is pragmatic, field-oriented, and results-driven, with a simple conviction: to sustainably advance the Supply Chain by combining business expertise, Lean culture, and team involvement.

I had the pleasure of working with Gael for six months on the development of our maintenance business across several regions worldwide. Gael integrated seamlessly into the team and demonstrated exemplary professionalism. He brilliantly led his project for global and local inventory optimization, based on consumption analysis, lead times, and the creation of a high-performing forecasting model. He not only met but exceeded the set objectives, while delivering sustainable tools and training the teams. Gael also contributed to the implementation of management dashboards and led a major project to improve On-Time Delivery, by structuring a solid methodology and effectively mobilizing the teams. I highly recommend Gael for his expertise, his rigor, and his ability to drive projects forward in a concrete and collaborative manner. He is a real asset to any supply chain or continuous improvement project.
