ENGINEERING · ECONOMICS · STRATEGY

Understanding systems. Acting on their transformation.

An engineering student at Mines Saint-Étienne and a final-year Applied Economics undergraduate at Dauphine-PSL, I work part-time at ArianeGroup within the Procurement Department on the Ariane 6 programme.
I also serve as a Municipal Councillor in Villefranche-de-Rouergue and an Intermunicipal Councillor at Ouest Aveyron Communauté.

My path combines economic analysis, industrial understanding and governance experience to inform strategic decisions and their conditions for execution.

Portrait of Jan Vaissière

A hybrid background

Three dimensions of a single line of reasoning

01

Strategy, economics and finance

Analysing organisations, their models and their trade-offs to understand what creates value, what constrains decision-making, and what makes transformation possible.

02

Industry and operations

Testing analysis against reality: costs, lead times, suppliers, data and coordination. Industrial experience shows how a strategy translates — or fails to translate — into action.

03

Governance and public action

Understanding how collective decisions are built, amid diverging interests, institutional constraints and territorial responsibility. An essential lens for grasping transformation beyond the firm.
