Traceability Metrics

What are Traceability Metrics?

Traceability metrics measure how completely requirements are linked to test cases (and vice versa), typically tracked using a Requirements Traceability Matrix (RTM).

What the RTM Shows

• Which requirements have corresponding test cases and which do not.
• Which test cases map back to which specific requirements.
• The pass/fail status of tests, mapped back to requirement coverage.

Why Traceability Metrics Matter

• They ensure no requirement is left untested.
• They help assess the impact of a requirement change on existing test cases.
• They provide clear evidence of coverage for audits and compliance.
