What is a traceability matrix?

A traceability matrix also known as Requirement Traceability Matrix(RTM) is a document that is used in the development of the software application to trace the requirements proposed by the client to the system being built. Some of the features of RTM are-

• It is prepared before test execution to make sure that all the requirements are covered in the test cases.
• The test engineers will prepare RTM for the respective assigned modules.
• These will be submitted to the Test Lead.
• The Test Lead will verify the specific module RTM to see if all the requirements of that module are mapped to corresponding test cases and in the end, will consolidate all the RTMs and prepare one necessary RTM document.
• The main purpose of RTM is to check that all requirements are checked via test cases.
