Multi-view variation modeling for scenario analysis

We propose an approach using scenarios to describe a spectrum of possible futures and analyze them to assess and improve the ease of accommodating new requirements by a system architecture. Variation modeling forms an important part of the analysis. This paper focuses on an approach to variation modeling across multiple architectural views. The models do not only display the variability in these views, but also the relationships between them. In particular, they can show how choices in one view influence choices in the other views.
