A requirements trace matrix (RTM) is a tool that helps to ensure that the project’s scope,

requirements, and deliverables remain consistent and aligned throughout the project lifecycle. It

traces the requirements from their origin to their fulfillment by linking them to other project

artifacts, such as design documents, test cases, and solution components. An RTM can also be used

to verify that all requirements are met and to identify changes to the scope when they occur. An RTM

is especially useful for smaller projects where there are few requirements, as it can help to track the

progress and status of each requirement and avoid scope creep. A requirements trace matrix is not

the same as a roles and responsibility matrix (A), a RACI matrix (B), or a coverage matrix ©, which

are different types of matrices that serve different purposes in project management. Reference:
