In this paper we want to show how MDE (Model Driven Engineering) approaches may help solving some practical engineering problems. Our view of MDE is not based on the usage of huge and rather monolithic modeling languages like UML 2.0 but instead on small DSLs (Domain Specific Languages) defined by well focused metamodels. As a consequence we use a rather "agile" view of MDE where each tool is characterized by one of several metamodels and where the interoperability between tools is implemented by specific model transformation operations. We base our discussion on a practical illustrative problem of bug-tracking in a collaborative project involving different partners using tools at different maturity levels. We conclude by discussing the help that MDE approaches may bring to solving these kinds of situations.
