Presentations

Presentations are where many careers become visible. A clear, confident pitch to a client, an update to senior leaders or a talk at an industry event can do more for your reputation than months of quiet work. Yet many people fear public speaking more than almost anything else, and many presentations waste the audience's time with crowded slides read aloud. This lesson takes you through planning, structuring, designing slides, timing, delivering, handling questions and presenting online. The same principles of purpose, audience and plain language that guide your writing guide your speaking too, with one big difference: listeners cannot reread. A presentation must be simpler and more repetitive than a document to be understood.

Planning: purpose, audience and the big idea

Begin, as with any message, with purpose and audience. What should the audience know, believe or do at the end? Who will be in the room, what do they already know and what do they care about? How much time do you really have, and what happens before and after your slot? Then write your big idea: one sentence that states your point of view and what is at stake. The presentation designer Nancy Duarte recommends exactly this, and it is a useful discipline. "Our customer churn is rising" is a topic; "We will lose $1.2 million in revenue next year unless we fix onboarding in the first 30 days" is a big idea.

Consider the context, too. A five-minute update in a weekly meeting, a 20-minute pitch to a client, a 45-minute conference talk and a two-minute elevator pitch need very different levels of detail. A board presentation may be preceded by a written briefing, so the slides can focus on discussion. A virtual presentation may be recorded and watched later at double speed.

Structuring the talk

A presentation needs a clear opening, body and close, with signposts that tell the audience where they are. Many speakers follow the old advice: tell them what you are going to tell them, tell them, then tell them what you told them. That repetition, which would be tedious in a report, helps listeners who cannot flip back.

Organize the body with a pattern the audience can follow: problem and solution, chronological, by topic, comparison of options, or a persuasive sequence such as Monroe's motivated sequence (attention, need, satisfaction, visualization, action), which resembles the AIDA pattern from lesson 6. Limit yourself to two to four main points. Audiences remember little of what they hear; three well-supported points beat ten rushed ones.

Timing and speaking rate

Conversational English is commonly spoken at about 130 to 150 words per minute in presentations, a little slower than everyday conversation, with pauses. You can use this rate to plan the length of a script or speaking notes, and to check whether your content fits the time. Leave a margin of 10 to 15 % for pauses, audience reactions, a slide that takes longer than expected and transitions.

Designing slides

Slides are visual aids, not a script and not a document. If the audience is reading dense text on a slide, it is not listening to you. Effective slides follow a few principles. Put one idea on each slide, stated in a headline that makes the point (a takeaway title, as for charts). Use images, charts and diagrams more than text. Keep text to a minimum; one common rule of thumb is no more than about six lines of about six words each, and many designers aim for far less. Use large type: body text of at least 24 points and headlines of 32 or more in a large room. Use high contrast and a simple, consistent template. Build complex diagrams step by step. Put details in a handout or follow-up document rather than on the slide.

Rules of thumb for the number of slides vary widely. The venture capitalist Guy Kawasaki popularized a 10/20/30 rule for pitches: 10 slides, 20 minutes, no font smaller than 30 points. Others suggest about one slide for every one to two minutes. The right number depends on the content; a slide that shows a single photo may last 15 seconds, while a key chart may stay up for three minutes.

Delivery

Choose a delivery method that suits the occasion. Reading a full script word for word is rarely effective, except for formal statements where exact wording matters (such as a legal or media statement). Memorizing a whole talk is risky; a memory slip can derail you. Most business presenters speak extemporaneously: well prepared and rehearsed, from brief notes or the slides, but not word for word. Rehearse aloud at least three times, once in front of a colleague or a camera, and time each run.

Your voice and body carry much of your message. Speak a little slower than feels natural, vary your pitch and pace, and pause before and after key points. Make eye contact with individuals around the room for a few seconds each. Stand with a stable, open posture and use natural gestures. Avoid filler words (um, like, so) by pausing instead. Nervousness is normal and usually invisible to the audience; preparation, slow breathing, arriving early to check the equipment and focusing on the audience's needs rather than your own performance all help.

Handling questions

Question periods let you clarify, persuade and show expertise, but they can also go off the rails. Prepare by listing the ten questions you would least like to be asked and drafting short answers. During the session, listen to the whole question, repeat or paraphrase it so everyone hears it (and so online participants and recordings capture it), answer briefly and check that you answered it. If you do not know, say so and promise to follow up by a specific time. With a hostile question, stay calm, acknowledge the concern, respond to the substance and avoid arguing. If one person dominates, offer to continue the conversation afterward.

Presenting online and in hybrid settings

Virtual presentations need extra preparation. Check your camera, microphone, lighting and internet connection beforehand, and have a backup (a phone dial-in and slides already shared with a colleague). Put the camera at eye level and look at it, not at the screen, when making key points. Engage the audience every few minutes with a poll, a question in the chat or a direct question to a participant, because attention online drops quickly. In hybrid meetings, make sure remote participants can see the slides and hear every question, and invite them to speak first sometimes. Turn on live captions where available, which helps people who are deaf or hard of hearing and anyone with a poor connection.

Portfolio task for lesson 9: prepare a five-minute presentation of the recommendation report you wrote in lesson 7. Write a big idea, outline two to four main points, design no more than six slides with takeaway headlines and time your rehearsal. Record yourself once and note three improvements.
