Give people a grace period to get comfortable
Nobody gets good at a new tool overnight, yet plenty of rollouts quietly expect full fluency within days, which leaves people feeling behind before they've even had a fair shot. I say this part out loud every time now, because I've watched people quietly give up on a tool simply from feeling like they should already be faster than they were. Set an actual grace period, maybe a stretch of a few weeks, where mistakes and slow going are expected and nobody gets side-eyed for asking a basic question. Say this out loud so people know it's real and not just something you assumed they'd figure out on their own. This kind of patience actually speeds up real adoption, because people who feel safe experimenting try more things than people who feel watched and judged. Rushing past this stage is how teams end up with a tool that only the fastest few ever really learn to use well.
Try this today: announce a clear grace period for your newest tool and tell your team plainly that slow going and questions are expected, not a problem.
