Lionel Chambet

I am an expert in defining, managing, steering, and securing a transformation, combining business impacts with the implementation of new tools or solutions, particularly with Data and AI.

My expertise lies in securing and accelerating the implementation of a program, with practical, ground-level operational pragmatism, while ensuring proper reporting to the Steering Committee or Executive Committee, in order to track the program's ROI and Value creation.

I work on complex transformation programs when execution needs to be accelerated, delivery secured, or operational performance rapidly improved.

After more than 25 years at Accenture, IBM, and Capgemini Invent, I support general management and executive committees on high-stakes business and operational transformations.

My role: align business, IT, and data teams, restore effective governance, and deliver concrete results in demanding environments
