ICH E6(R3) tells you what investigators and sponsors are obligated to do. ICH E2A tells you what the terms mean and which categories trigger which reporting pathways. And 21 CFR Part 312 -- the FDA's regulations -- tells you what happens when those obligations carry the force of United States law, complete with specific calendar-day deadlines and enforcement consequences.

If you understand only one of these frameworks, you will have gaps. If you understand all three and -- more importantly -- how they interrelate, you will understand why your protocol's safety reporting section is written the way it is. And that understanding is what separates a coordinator who follows instructions from one who comprehends the system well enough to catch errors before they become compliance failures.
