RE: [AM] Why Traceability?

Translating some requirements into executable tests can be difficult.  Tracing requirements to code in a dynamic code base is also difficult, and a lot less useful.

80-90% is not bad at all. Agility is not about perfection.

If the difficulty is that the requirements are about presentation or some other aspect of the GUI, then I try to write acceptance tests using the objects just below the GUI and try to get my team to write as thin a GUI layer as possible to minimize the chance that the acceptance test succeed buyt the GUI fails.  There are other approaches.

If GUI is not the problem, then it is likely that the requirement is too vague or too broad.

I'd have a difficult time translating all of the requirements I receive into
executable tests. I find that probably 80-90% could be pretty easily
expressed as tests but the rest would take quite an effort to map over. Do
you also have this problem? How do you handle it?
