Aspect Model-Based Methods for Scenarios and Prototype Development

Prototyping is a critical method for exploring, communicating and testing new concepts in an interactive system development process. However, the criteria used in prototype model evaluation often do not address the original project objectives and issues. To improve this situation, a prototyping specification mechanism with aspect models and scenarios created through the aspect models are introduced, using Design Information Framework (DIF) as a foundation of organizing information necessary for prototyping. Scenarios created through the aspect models are introduced for prototype testing context definition. This paper presents the prototyping specification mechanism with its application.
