Multi-VisioTrace: Traceability Visualization Tool

Traceability supports various activities of the software development process, such as impact analysis of changes, reuse, maintenance, verification and validation. The graphical representation of traceability information is very important to its effective use in those activities. Visualization tools can help in the interaction with large amount of data, in the identification of characteristics, patterns and trends. However, visualization tools are usually built for a specific domain, and generally support a single visualization technique. Therefore, they do not meet appropriately the needs of different contexts. This paper presents a tool to support traceability visualization that provides different visualization techniques, allowing the user to choose the most appropriate to his/her task; the evaluation results of the proposed tool are presented through two studies.
