When you, or your boss, have to give a presentation with a strict time limit, you need to have every word down pat so you can ensure you hit all the key points. The only way to do that is to practice—a lot.
Start by writing the speech—every word of it, advises Dave Johnson. Then practice, cut down and repeat until the entire speech fits comfortably within your time limit.
Once it’s at a good length, break it down into smaller parts, and practice until you’re used to how much time each section should take.
