From Model-based to Natural Development

Model-based approaches aim to support development through the use of meaningful abstractions in order to avoid dealing with low-level details. Despite this potential benefit, their adoption has mainly been limited to professional designers. This paper discusses how they should be extended in order to obtain environments able to support real end-user development, by which designers can develop or modify interactive applications still using conceptual models but with a continuous support that facilitates their development, analysis, and use.
