Software product line engineering (SPLE) promises order-of-magnitude improve-ments in time-to-market, cost, productivity, quality, and other business drivers. Many of these expected benefits are based on the assumption that the additional investment for setting up a software product line pays off during application engineering. However, to fully exploit this we need to optimize application engineering processes and systematically and efficiently handle reusable artifacts. The goal of this workshop is to explore and explicate the current status within the field of model-driven approaches in SPLE. The workshop has the following aims:
