Preface Quality constitutes an important topic in software engineering and becomes an essential issue in studies on using models in software engineering. Software quality management is already widely researched and approached from multiple perspectives and viewpoints. However, the introduction of a new paradigm in software development – namely Model Driven Development (MDD) – raises new challenges in software quality management, and as such should be given a special attention. The goal of this workshop was to gather researchers and practitioners interested in the emerging issues of quality in the context of MDD. The workshop is intended to provide a forum for presentation and discussion of emerging issues related to software quality in MDD. The workshop is built upon the experience and discussions during the previous workshop on Quality in Modeling and a series of workshops on model consistency held annually at the UML and at EC-MDA conferences. The intention of this year’s workshop was to extend the scope of the previous activities and to contribute with possible post workshop joint activities. During the last year workshop at MoDELS 2006 there was a consensus that the issues of quality of models need to be researched from various perspectives – both industry practices and academic research hence industry perspective is intended to get a particular attention in this edition. Workshop is divided into two parts: Presentation part – when the accepted paper contributions were presented and discussed, Working part – when a guided discussion was conducted aimed at elaboration of a common quality model. The presentation part consists of two sessions, dedicated mainly for the presentation of accepted paper contributions with ample time allocated for questions and discussion and is structured into two sessions: Quality frameworks and models, Quality in practice. The rationale behind the working part was to carry out a prearranged discussion on a structured approach to quality in modeling, aimed at acquiring a common quality model. A short introduction is to be presented, followed by concise position statements of all participants based on addressing three questions related to model quality: What qualities of models and modeling matter? How do they relate to each other? How can they be measured? The statements are to be based on an existing quality framework, sent to the participants, aimed at unifying and structuring the answer to the questions. An ample time for discussion based on the statements was allocated. The contributions will be combined into a common quality model which will be published in the workshop results report.
