Dalus + Polarion
Polarion stays the requirements database your quality process is built on. These add the half it cannot hold: an architecture the requirements point at, a traceability chain that runs all the way to test results, and a round trip that raises a change request rather than editing anything you have frozen.
3 workflows
Polarion requirements to architecture
Give Polarion requirements an architecture to point at, one accepted link at a time.
Polarion traceability gap report
Requirement to architecture to verification to result, with every break in the chain named.
Polarion round trip without breaking baselines
Changes come across into In Work requirements. Frozen ones get a change request instead.
