Vertical sub-contracting relationships strategy, the Airbus First-tier suppliers\' coordination

Abstract

This paper analyzes the transformations of industrial vertical relationships, and more particularly the duality of the coordination modes within new industrial architectures. The paper aims to characterize relationship between the architect and the first-tier suppliers according to the strategic degree of their competence. Two models of coordination arm\'s length and systems integration coexist within the same industrial architecture. The recourse to one or the other varies according to the policy of purchase and the strategic degree of the sub-contracted subsystems. Thus we will analyze the system of subcontracting of Airbus by focusing to the importance of the purchasing policy. The argumentation articulates in two parts. The first one considers the vertical subcontracting relationships in the framework of complex productions, by insisting on organizational aspects. The second one analyses the transformation of the \"Airbus\" productive system by focusing on purchasing process and the emergence of new First-tier supplier’s coordination modes.NAModularity – Systems Integration – Strategic competences – Purchasing Strategy – First Tier Suppliers – Airbus
