Pilot acceptance test-driven development for QSR

Consider the ATDD variant for the QSR 1.3 project.

It would help to get transparency to the current progress via the accepted work products and verification results. Add once everything is ready for the certification, the project is about to complete. So we can call it Certification Readiness Driven Development (CRDD), or Fast Agile Review and Testing (FART) driven development etc...
