TRAM: a tool for requirements and architecture management

Management of system requirements and system architectures is part of any software engineering project. But it is usually very tedious and error prone. In particular, managing the traceability between system requirements and system architectures is critical but difficult. The article introduces a tool, TRAM, for managing system requirements, system architectures and more importantly the traceability between them. Its primary design objective is "being practical" and ready for practitioners to use without much overhead. The issues discussed in the paper include an information model that underlies the capture of requirements, architectures and their traceability, a set of document templates implementing the information model, and the support tool.
