Research on Dynamic Requirement Traceability Method and Traces Precision

Based on the current research on the dynamic requirement traceability (DRT), this paper investigates the trace precision problem in depth and proposes a solution-dynamic requirement traceability framework.This framework focuses on automatically establishing traces and combines the traditional requirement traceability activities with change proposal, impact analysis and change control, etc.It makes full use of the characteristics of artifacts and evolutional information of change in the iteration process so as to help establish the requirement traces with higher precision.
