Good traceability between the test basis and test work products provides several advantages: i.Analyzing the impact of changes:Traceability allows for easy identification of which parts of the test work products will be affected by changes in the requirements or design, facilitating impact analysis. iv.Making testing auditable:Traceability ensures that there is a clear connection between the requirements and the test cases, which makes the testing process auditable and provides evidence that all requirements have been tested​​.
