An Abstraction-Driven Approach for Complex Model-Based Software Development

This paper proposes to use abstraction level as the dominant driving force to guide the development of complex model-based software system, in place of the linear SDLC, ad hoc prototyping, top-down structured method etc. Based on this abstraction-driven approach, the paper suggests to use a downward spiral process model, incorporating the dual structural and behavioral system models into the development. Golden ratio is used to locate the progression balance between abstraction level and models at different spirals. The contributions of the paper include a re-prioritization of development emphasis and unifying split system models towards one system solution.
