A Survey On Accuracy Of Requirement Traceability Links During Software Development

Traceability is used to ensure that source code of a system is consistent with its requirements. The only specified requirement has been implemented by developers. During software maintenance and evolution, requirement traceability links become marginal because no developer can devote effort to update it. However, to recover traceability links later is a very painful and monotonous task also it is costly for developers too. Traceability supports the software development process in various ways, like as change management, software maintenance and prevention of misunderstandings. But, while, in practice, traceability links between requirements and codes are not created during the development of software as it requires extra efforts. So developers rarely use such links during development
