Requirements Tracery

This paper presents traceability of software. Traceability expresses the potential to create and follow links between pairs of development artifacts to support analytical or development tasks. While a traceability information model or some similar specification of permissible links between artifact types can predefine the intended types of trace to establish and use, the overall tracery obtained in practice is rarely designed or scrutinized. The sum total of the actual traces created within a project provides the scaffolding for supporting many diverse engineering activities. They deserve far more attention.
