According to Sommerville & Sawyer [18] requirement engineering involves the activities for discovering, documenting and maintaining a set of requirements for a computer-based system. Requirement engineering activities are often divided into five categories. These categories include requirement elicitation, requirement analysis, requirement specification, requirement validation and requirement management.
Abstract
Requirements traceability provides support for many software engineering activities like impact analysis, requirements validation and regression testing. In addition requirements traceability is the recognized component of many software process improvement initiatives. Requirements traceability also helps to control and manage evolution of a software system.This thesis presents a systematic review and a framework for requirements traceability.
