What’s the best way to talk to a top performer who misses deadlines?

I’m struggling with how to handle a key team member who is technically brilliant but consistently misses deadlines, which is starting to affect project timelines and morale. I know I need to address the performance issue, but I’m worried about damaging their motivation or causing defensiveness. Has anyone found an effective way to structure this kind of conversation?

I tried a private chat where I started with what actually mattered to the project, not blaming them. I named the concrete deadlines missed and the knock-on effects on the rest of us. Then I asked what was really blocking them, not what I assumed. We landed on a single milestone, a clear owner, and a weekly check‑in to surface blockers. It helped a bit, but the deadlines still slipped and I felt we hadn’t fixed the momentum.

Another time I split the work so they owned a high impact piece with fewer handoffs, hoping that autonomy would boost momentum. They still delivered late on that piece, though the quality when they did show up was excellent. Morale ticked up a notch for the team, but the schedule didn’t get clean.

Maybe the real problem isn’t motivation but how we estimate and scope things in the first place; if the plan is fragile, deadline pressure just exposes that. It’s worth checking whether our estimates are honest or if scope creep is the real driver behind the misses?

Last time I tried softer language and fewer reminders, but the person felt slightly smothered. We pulled in a couple of tasks to re-balance, and the issue persisted. Not sure if I should have kept firmer guardrails or given more space.
