Poirot: A Distributed Tool Supporting Enterprise-Wide Automated Traceability

Poirot is a Web-based tool supporting traceability of distributed heterogeneous software artifacts. A probabilistic network model is used to generate traces between requirements, design elements, code and other artifacts stored in distributed 3^rd party case tools such as DOORS, rational rose, and source code repositories. The tool is designed with extensibility in mind, so that additional artifact types and 3^rd party case tools can be easily added. Trace results are displayed in both a textual and visual format. This paper briefly describes the underlying probabilistic model, and the user interface of the tool, and then discusses Poirot´s deployment and use in an industrial setting
