In order to ensure the quality of their software development, companies incorporate best practices from recognized repositories or from their own experiences. These good practices are often described in software quality manuals that, in this form, do not guarantee their implementation. In this paper, we propose a framework for the implementation of best practices.We treat the case of modeling activities because they are becoming the main activity of software development processes. Our framework enables on the one hand to describe the good practices and on the other hand to check their application by the designers. We present an implementation of our framework in the Eclipse platform and some examples of use of our approach in the modeling of UML Class diagrams.
