A requirements traceability matrix (RTM) is a tool that helps to track the relationship between the requirements and the product features, test cases, and other artifacts. It can be used to ensure that all requirements have been met by verifying that each requirement has a corresponding feature, test case, and acceptance criterion. A RTM can also help to identify the risks associated with dependent requirements, but that is not its primary purpose. A RTM does not define a convention to map the requirements to their sources, but rather uses an existing convention or standard. A RTM does not address the responsibility owner for each requirement, but rather shows the status and priority of each requirement.
