: Traceability and rationale management are highly important--especially in distributed collaborative software development projects due to a lack of mutual awareness and informal coordination among the participating stakeholders. Therefore this papers presents a tool for extracting, visualizing, and analyzing the relationships between requirements and other artifacts, activities as well as users within a distributed software project using a collaborative development environment. Underlying requirements and the conceptual design of this tool are based on several real-world use cases demonstrating the respective value contribution of the tool's functionality.
