Provide clear time guidelines and visual countdowns for speakers. Assign a moderator to manage transitions and use timed cues or warning signals to maintain the event schedule.

In order to keep speakers on track during a live event with strict time limits, you will need a combination of preparation, clear communication, and tools to manage time effectively.

It's important to have a prepared moderator. One with notes, or the outline provided by the speaker. Aa a speaker myself, I use a printed outline.

I believe the three main tips form the backbone of success in this challenge. What I see are ways to enhance these ideas. For instance, along with visual cues, subtle sound signals could help indicate the remaining time—like a chime at five minutes and another at two. Regarding the timekeeper, agreeing on specific keywords with speakers could discreetly signal if they exceed their limit. A brief rehearsal beforehand would also familiarize speakers with these signals. To avoid overruns due to questions, schedule a separate Q&A session outside the main presentation. A symbolic recognition, like a "Punctual Speaker" badge, could also be a great incentive. I believe these measures, combined with the original tips,can help reduce timing issues.

Use a chairman's buzzer it a little light you place on the lecturn, when you push a button it lights up to tell the presenter to hurry along, old school but effective
