Incident reports exist so we can learn from what went wrong and prove we took it seriously. The job is to capture the detail while it's fresh — a vague report a week later is worse than useless.
Stick to facts. Don't interpret, don't speculate, don't apportion blame. Avoid "I think" and "they probably" — if you're uncertain, write "I was told that..." or "according to {name}..." so it's clear you're reporting second-hand information.
