Build a short answer sheet instead of a memory test
New tools always come with a wave of small, repeated questions, like where a setting lives or what to do when a result looks off. I used to answer these one by one from memory until I noticed I was explaining the exact same thing to a different person every week. Rather than answering the same question five separate times over a couple of weeks, write a short answer sheet the first time it comes up and point people to it after that. Keep it plain and specific, organized by the actual question someone asked, not by some abstract category that only makes sense to you. This turns your team's memory into a shared resource instead of relying on you personally remembering every detail forever. It also means a new hire six months from now gets the same clear answer as the person who asked first, without you having to explain it all over again.
Try this today: the next time someone asks you a question about a tool, write the answer down in a shared spot instead of only answering them out loud.
