L'impact de l'utilisation de modèles sur les systèmes d'entreprise : application dans une entreprise de production de tubes sans soudures

Quantitative researches are meant to develop universal rules and to apply those rules on different cases. Case study researches are meanly focused on a given phenomenon under study with a major attention given to the case design and the research question to answer. In this article, we present a case study aimed at understanding and controlling the use of process models in an enterprise. We address three processes: Supply Chain Management (SCM) process, Product Lifecycle Management (PLM) process and Customer Relationship Management (CRM) process. After identifying each one of these processes in the enterprise, we work on: -Identifying the conspicuous knowledge in a process model, the knowledge necessary for the building and the application of a model along with the knowledge necessary to maintain the interoperability between different process models. This knowledge emphasises the interaction between the model and the enterprise Knowledge System (KS). -Extracting the information flows used in the studied models, theses flows emphasise the interaction between the model and the enterprise Information System (IS). -Explaining an "effective model's application" in order to maintain the coherence of enterprise systems, especially the IS and the KS. Data collection is mainly achieved by conducting semi-directed interviews with managers from different departments. The Data collection is not completed yet, so we present the Data analysis as a perspective work in order to conclude our case study.
