Traceability matrix is a document that maps and traces user requirements with test cases. The main aim of Requirement Traceability Matrix is to see that all test cases are covered so that no functionality miss during the software testing.
A traceability matrix is a document used in software development and quality assurance to link requirements throughout the development life cycle. It establishes a clear and systematic relationship between various project artifacts, such as requirements, design elements, test cases, and more. The main purpose of a traceability matrix is to ensure that all requirements are addressed and validated through the development process, and that changes to one set of artifacts are reflected in the others.
In essence, a traceability matrix helps to trace the development and testing of each requirement from its origin to implementation and testing phases, ensuring comprehensive coverage and alignment with the project goals.
