RTM stands for Requirement Traceability Matrix. The requirement traceability matrix is a high-level document to link and track requirements with test cases to ensure that each requirement testing is achieved. Reviewing all the test cases for any requirement is called Traceability, enabling us to determine which requirement has the most defects. The benefit of RTM are: An RTM can be used to manage changes to a project's Scope and evaluate the impact of these changes. It will be easier to assess the effect of making any changes to one or more requirements if you know how they are related. An RTM ensures stakeholders trace back the project's objectives and solution. An RTM ensures that approved requirements should be delivered at the end of the day. Solution requirements can easily be linked back to business requirements using RTM.
