Abstract
In Model-Driven Engineering (MDE), models are the prime artifacts, and developing high-quality systems depends on developing high-quality models and performing transformations that preserve quality or even improve it. This paper presents quality goals in MDE and states that the quality of models is affected by the quality of modeling languages, tools, modeling processes, the knowledge and experience of modelers, and the quality assurance techniques applied. The paper further presents related work on these factors and identifies pertinent research challenges. Some quality goals such as well-formedness and precision are especially important in MDE. Research on quality in MDE can promote adoption of MDE for complex system engineering.
