During its first fifteen years (from 1988, date of its creation, to 2003), STI GENLIS assembled automotive locks on behalf of a world tier 1 automotive supplier. The industrial requirements of this principal would forge the positioning and the corporate culture of STI GENLIS: flexibility, responsiveness, efficiency in industrial organization (5S, Kanban, lean manufacturing, etc.), permanent search for productivity leads, organization of the continuous improvement system (ISO certification), etc.
In the mid-1990s, the industrial policy of the automotive sector evolved towards the establishment of new factories in low-cost countries, generating a sharp and continuous drop in the volumes entrusted to subcontractors such as STI GENLIS.
