8.7.1 Comprehensive Requirement Traceability Information, and Relations in Project Life‐Cycle

Proper management of requirement traceability information is vital for the project success. Often, it is debatable what to trace and how, without burdening the engineer with useless information. Requirement engineering in context of hardware intensive systems employs different techniques for traceability recovery, and management. In this paper, we have tried to address the problem of requirement traceability in context of hardware intensive systems' requirement engineering. We have classified the information, which needs to be traced in eight categories, and distinguished their usage in various systems engineering activities throughout the project lifecycle. We have tried to specify the degree of granularity of information at various levels, and their relationships between various levels. We used SysML to present our approach through an example.
