I want to take whatever time we have left here to explore something we haven't explored before. How does SMS get implemented? Is there an exchange of correspondence? Are there reports, letters, memos, meetings? And who attends these? Are the flight attendants involved? Is their opinion sought? Are the pilots involved, and is their opinion sought? Are there meetings, and are there inspectors at these meetings?
Do you have a sense of how these systems get implemented? It might be helpful in understanding how they eventually would operate or are operating, in some cases.
