What is a requirements traceability matrix?

Requirements Traceability Matrix (RTM) is a project management tool that links requirements to their implementation and testing. It helps track whether each requirement has been considered and verified in the project.

RTM typically is a table where:

• Rows list the requirements.
• Columns indicate related artifacts: project documentation, design, code, test cases.

This ensures transparency and control over the completeness of requirement implementation, helps identify gaps, and manage changes in the project.
