Abstract: Requirement Traceability (RT) is one of the crucial activities in managing requirements. In addition, RT is important part of developing software projects. Research has shown that RT influences positively on the quality of software products. Nevertheless, there is a lack of guidance available for practitioners to assist them to establish effective traceability in their projects. In this study, we present Systematic Literature Review (SLR) of requirement traceability practices. This study enables practitioners to find a suitable method for tracing requirements and also enables researchers to find gaps and pointers for future study in this domain.
