Contribution de la gestion des risques logistiques à l’évolution des systèmes d’information intégrés de type ERP (Enterprise Resource Planning) en phase de post-implémentation : une approche longitudinale appliquée au secteur aéronautique

摘要

AImplementing an integrated system, such as an ERP, is not without consequences. However, only a few studies have looked at post-implementation. The focal point of our research is the capacity of the ERP to evolve after being implemented, when confronted to changes of needs of the organization and its ecosystem, in particular concerning logistical dimensions. Indeed, logistics is often at the origins of major reconfigurations – risks that need to be integrated by an ERP system, whose rigidities have been abundantly addressed in publications. It is thus interesting to examine different mechanisms that would enable to have the ERP evolve, in order to keep it consistent with the needs, the strategy and the performance of the company. This question is at the heart of this thesis on the contribution of the management of logistics risks on the one hand, to underline the ERP misfits (Strong et Volkoff, 2010) and, on the other hand, to their evolution and adaptation (Besson et Rowe, 2011). Our methodology is essentially qualitative and relies mainly on a case study, with three phases of non-participant observations made in an aeronautics company whose ERP system is stable. Our observations, documentation and interviews show the software package is an asset for logistics robustness in the short term and, at the same time, a disadvantage in front of logistics risks, which will be either accepted without the ERP evolving, reduced with the evolution of the ERP or avoided with the actual bypassing of the ERP. In all cases, the management of logistics risk appears as a tool enabling the continuous evolution of the ERP configuration and so improving its alignment and performance.
