What Is Requirement Traceability Matrix

Requirement traceability matrix (RTM) is a document used in software testing to track the requirements throughout the software development life cycle. It is a table that maps the requirements with the test cases that verify them, ensuring that all requirements are tested and that there are no gaps or duplications.

An RTM typically contains the following information:

Requirement ID: unique identifier for each requirement
Requirement description: a brief description of each requirement
Test case ID: unique identifier for each test case
Test case description: a brief description of each test case
Test case status: whether the test case has been executed, passed or failed
Comments: additional information or notes related to the requirements or test cases
RTMs are helpful in ensuring that all requirements are tested, and the software meets the customer’s needs. They help in maintaining traceability and accountability throughout the testing process. Additionally, RTMs can help in identifying gaps or missing requirements, making sure that all requirements have been addressed.
