this paper shows an overview of state of art on Traceability which is defined as the ability to trace history, application or location of an entity by means of recorded indications. It is important to point out monitoring of Requirements Engineering on different stages in order to warranty quality software, since it represents a process of analysis and detailed study. When changes occur in software, traceability makes it relatively easy to assess impact that changes could have on other parts of development process; this allows following of steps in software requirements, as shown in this research.
