Due to the rising complexity, time-to-market demands, and variability involved in building requirements of critical hardware and software systems, it is absolutely essential to have a robust requirements sign-off capability. It's particularly applicable for systems where the financial cost of failure is significant, when systems are safety-critical, or where there is a high security factor.
Current industry practice: "Mind the Gap"
Even though a wide array of tools is available for analysing source code and testing executable code, there are no tools that automatically track the results of tests as they apply to requirements.
Current common practice in requirements tracing stops at test definition, leaving unattended the need to ensure that requirements have tests defined against them and that these tests have successfully completed. This creates a gap between the requirements capture tools available and the features available in the wide array of test-only products.
