Model Driven Development of Business Applications - A Practitioner's Perspective

We discuss our experience in use of models and model-driven techniques for developing large business applications. Benefits accrued and limitations observed are highlighted. We describe possible means of overcoming some of the limitations and experience thereof. A case for shift in focus of model driven engineering (MDE) community in the context of large enterprises is argued. Though emerging from a specific context, we think, the takeaways from this experience may have a more general appeal for MDE practitioners, tool vendors and researchers.
