Technical Direction, Plastic Omnium They allowed us through their analytical and back office methods to broaden the spectrum of our supplier panel for new components in a time frame that we were unable to respect with our internal resources and methods.
Purchasing Management, SEB The methodology used and the quality of the speakers allowed us to overcome all the difficulties of this project to make it a success.
Technical Direction, Schneider Electric IAC quickly provides a strong synthesis and analysis capability that accelerates projects.
R&D Direction, BÉABA IAC’s coaching has contributed positively to mastering our development and its delicate planning and cost aspects. The implementation of methods and procedures of analysis piloted by IAC has enriched our thinking and allowed us to select with more certainty the technological choices and suppliers. In today’s industrial world, the openness given by IAC and the effective commitment of their team is an undeniable project asset.
Technical Direction, France Fermetures Systematic analysis of the product and practices around the product has allowed us to generate significant gains while equipping ourselves with a product that better responds to its market.
Product Management, Alstom The reduction in overall cost has exceeded the initial assessment which seemed ambitious.
General Management, Groupe Compin Whatever the size and level of complexity of an enterprise or project, their consultants know how to adapt to it in order to lead our teams to the best results.
Industrial Management, Faiveley transport The presentation of the results has generated considerable interest which has been widely used to enrich the analysis of the industrialisation process at all levels of the Business Unit.
Technical Direction, Salomon This is a success. Their team was able to challenge and motivate teams despite a challenging environment.
Industrial Operations Division, SEB Within Groupe SEB, we have had the opportunity to involve the company in numerous major engineering projects. We particularly appreciated their ability to move lines and embark our teams from strategic marketing, to industrial operations, through all aspects of product creation.  
Energy and Boiler Director, EIFFAGE MÉTAL For EIFFAGE MÉTAL, unfamiliar with the use of consultants in operational process improvement, this assignment was of strategic importance beyond the project's objectives. IAC's offer reassured us by its transparency and its adequacy to our needs. The execution met our expectations, succeeding the human challenge, which was to secure the commitment of the project's operational staff. IAC also participated in meetings with our client, helping to secure their trust.
