Description: The Requirements Traceability Matrix (or RTM) is usually developed in concurrence with the initial list of requirements and is updated simultaneously with the newly-developed design specifications and test protocols.

What is the purpose of a traceability matrix?

A traceability matrix in software testing — otherwise known as a test matrix — is used to prove that tests have been run. It documents test cases, test runs, and test results. Requirements and issues may also be used in a test matrix.

Is traceability matrix is created only at the end of the project?

Traceability Matrix is prepared once the requirements are gathered and after the release post QA sign off we generate the RTM(Requirement Traceability Matrix) from HP ALM QC(Test Management Tool ) as I am using HP ALM its done this way.
