RESUME. Il existe de nombreux modèles de processus dédiés à l'ingénierie des systèmes d'information. Ils sont basés sur des concepts (activité, produit, décision, contexte, stratégie)ABSTRACT. There are many process models for information systems engineering, based on different concepts (activity, product, decision, context, strategy) and then on different process meta-models. These meta-models allow a partial vision of the process engineering. This paper presents a design pattern to model concepts of various process meta-models. This pattern is a first step towards the construction of unified, fitted and multi-views process meta-models. MOTS-CLÉS : modèle de processus, ingénierie des processus, patron, méta-modélisation.
