COSMOD-RE: Supporting the Co-Design of Requirements and Architectural Artifacts

The need for co-designing requirements and architecture for innovative software-intensive systems is widely accepted. In this paper, we present the key ideas of our method COSMOD-RE for supporting the co-design of requirements and architectural artifacts. The backbone of COSMOD-RE is a hierarchy of four abstraction layers. At each layer, a requirements viewpoint and an architectural viewpoint are co-developed and aligned using a goal- and scenario-based approach. COSMOD-RE defines three co-design processes and five sub-processes for each co-design process to structure and guide the co-development.
