Model-Based Engineering (MBE) is an approach to the design, analysis and development of software and systems that relies on exploiting high-level models and computer-based automation to achieve significant boosts in both productivity and quality. The ECMFA conference series (formerly known as the ECMDA-FA conference series) is dedicated to advancing the state of knowledge and fostering the industrial application of MBE and related approaches. Its focus is on engaging the key figures of research and industry in a dialog which will result in stronger and more effective practical application of MBE, hence producing more reliable software based on state-of-the-art research results. ECMFA 2013 will be co-located with ECOOP and ECSA. The joint organisation of these key conferences provides a unique opportunity to gather practitioners and researchers interested in these fields, and allow them to interact with each other.
