Let your most curious person go first
Every team has someone who already pokes around with new tools on their own time. I look for that person first, before I look at anyone's title, because their honesty saves everyone else the trouble of learning the hard way. Let that person be the first to try AI on a real task instead of picking whoever seems most senior or most in need of help. Curious people troubleshoot on their own, ask good questions, and tell the truth about what worked and what felt clunky. That honest feedback is worth more than a polished demo, because it comes from someone who actually wanted to make it work. Once they have a small win, they become the person others ask for help, which takes the pressure off you to be the only expert in the room. This also keeps the rollout human, since the first stories people hear come from a coworker, not a memo. Word of mouth from someone trusted travels faster than any announcement.
Try this today: ask the person on your team who tries new apps for fun to pick one task and test it, then have them share what happened at your next team meeting.
