Qualité des modèles : retour d'expériences

The increasing complexity of information systems (ubiquitous systems, open enterprises, etc.) calls for the introduction of always new modeling languages. However, the development of new domain-specific languages makes the question about their quality, as well as the quality of the produced models, an important issue for the modeling of information systems. This article deals with this issue by exposing the lessons learnt from the past experiences both on the quality of the languages and of the models expressed using them. These lessons highlight the necessity of automatic tools to support the quality evaluation of models, the collective participation of all stakeholders in the evaluation process and the definition of a human-centered language and model engineering approach.
