Towards an i*-based Architecture Derivation Approach

Goal orientation, in particular the i* (iStar) framework, offers expressive models that support requirements engineering. On the other hand, the understanding of how requirements models are related to architectural design is still somewhat limited. In the past years, we have been investigating how to derive architectural models from i* (iStar) models, focusing on modularity. As a result we proposed a Strategy for Transition between Requirements and Architectural Models – STREAM. In this paper, we summarize the current state-of-the-art of the STREAM approach, point out its challenging aspects and describe current ongoing research. Our challenge is to support a broader set of architectural decisions as well as to provide means for partially automating the models transformations.
