Question handling begins with listening. Let the person finish, pause, and identify the actual question. Repeat or reframe it when useful, especially for a large audience. Answer the core question first, add supporting detail, and check whether the response addressed the concern. When you do not know, state that honestly and offer a reliable follow-up path.
Improvement requires more than repeating the presentation from the beginning. Rehearse difficult transitions, time-sensitive sections, technology changes, and likely questions separately. Use recordings and feedback to find one or two high-impact changes, then test them in the next rehearsal. Preserve strengths as deliberately as you fix weaknesses.
