Antoine Klein


Antoine started in 1990 in operational consulting in the automotive and luxury sector. He then developed a long collaboration with leaders in the food & beverage industry and cosmetics (Danone, Sodiaal, Coca-Cola, L’Oréal) in the fields of operations strategy and performance in Europe and internationally (China , Russia, USA, Australia, Mexico). After an entrepreneurial experience and 4 years as Partner of a large IT consulting firm, focused on digitalization and its impacts on manufacturing organizations, he joined Mews Partners in 2021 to develop the operations transformation offer and the agri-food / consumer goods segment.

Planning, scheduling of operations, preparation of orders, production order, transportation, quality control, etc. these so-called execution processes are fundamental to ensure the quality and the level of service expected. We work  on their effectiveness with the teams that run them. Remove activities, improve interfaces, outsource, equip, digitize some activities… are all considered as levers. Above all, what matters are the women and men who operate these processes. We work with them in situ to get their engagement and consider realistic levers. Our commitment often leads us to support implementation projects, to test solutions and ensure their sustainable roots. Mews Partners customers value this ability to make the connection between the steering committees and the teams on the ground.

What are the gains expected from execution Supply Chain projects?

All our delivery Supply Chain projects are supported by an economic analysis called “Business Case”. It determines the gains expected from the project. These gains can be translated into productivity gains or capacity gains. The “Business Case” sets the goal at first then follows gains achieved according to the progress of the project and the implementation of the performance actions plan. We believe that our interventions should generate at least 15% gains for our customers on the analyzed areas.

Methods and tools developed in-house by Mews Partners

Mews Partners consultants have developed their own tools and methods to drive Supply Chain performance projects. First, we have an issue benchmark costs basis of funding over 100 projects. This basis is made available to our clients during the phases of analysis. Then we have Lean & Agile tools developed in-house to work with field teams: grid maturity, process analysis, matrix stakes & accessibility, KIDs (Key Interface Datas),… We train our customers to use them.

We offer several methods of intervention

We articulate our approach around 4 types of intervention. From the assessment phase of the gains to the definition of the plan of action and implementation phases. We also support our clients specifically on phases of outsourcing logistics and transport.
