What is the role of a system requirement traceability matrix (RTM)?

The role of a system requirement traceability matrix (RTM) is to ensure that all requirements are addressed during the development process. This tool serves as a critical link between the requirements and the development tasks throughout the lifecycle of a project. By mapping requirements to design, implementation, and testing artifacts, the RTM helps verify that each requirement is fulfilled by the system being developed. This is essential for confirming that nothing is overlooked, which can lead to project issues or unmet user needs.

Additionally, the traceability matrix aids in managing changes in requirements, ensuring that modifications are reflected throughout the relevant documentation and development efforts. This systematic approach supports quality assurance and project management, making sure that stakeholders can track the progress and validate that the final product aligns with the original goals.

The other options do not accurately reflect the primary purpose of an RTM. Tracking project costs and timelines is generally managed through other project management tools. Visualizing system architecture may involve diagrams or modeling tools but does not directly relate to tracking requirements. Monitoring user feedback on system performance focuses on post-deployment evaluations rather than ensuring that requirements are captured and addressed during development.
