Slide deck: how to structure one before you make a single slide

A slide deck is a sequence of visual aids built to support something you are saying. That definition rules out most of what gets called a deck: the forty-slide document nobody presents, the appendix that grew a body, the file that exists because somebody asked for a deck rather than for an answer. Getting the structure right happens before any slide is made, and it is the part almost everyone skips.

Three questions decide the shape. What is this for — a decision, an update, a sale, a teaching session? Who is in the room and what do they already know? And what are the three things they must remember tomorrow? A deck that cannot answer those is a slide-making exercise, not a communication.

Structuring a slide deck

1. Write the three takeaways as sentences, in a text editor, before opening anything that makes slides. If you cannot write them, the thinking is not finished and slides will hide that rather than fix it.
2. Write the one-line summary the audience should be able to repeat. This becomes your opening slide, not your closing one — burying the point at the end works in cinema and nowhere else.
3. Sketch the sequence as headlines only. Each headline states a point, not a topic: Support costs doubled after the migration, not Support metrics.
4. Check the flow by reading the headlines alone, in order. If they tell the story on their own, the deck is sound; if they read as a table of contents, restructure now while it is free.
5. Only then make slides, one idea per slide, and move everything that is evidence rather than argument to an appendix.

Common shapes and when to use them

• Situation, complication, resolution — for decisions. State where things stand, what changed, what you propose.
• What, so what, now what — for updates. Facts, interpretation, the action you want.
• Problem, solution, proof, ask — for selling, internally or externally.
• Chronological — for retrospectives and incident reviews, where the order of events is the argument.
• Question and answer — for teaching, where each slide answers one question the audience is already holding.

Length follows structure, never the other way around. A deck with three takeaways and an appendix is usually ten to fifteen slides; if you have thirty and no appendix, you have written a document with the wrong tool, and the room will read it while you are still on slide four.

Decks that are not presented

A deck sent by email and a deck presented live are different objects, and merging them produces something that fails at both — too dense to present, too sparse to read alone. If it will be read without you, write more per slide and add a summary page at the front. If you will present it, strip the text back and let the speaking carry the detail. When both are needed, the honest answer is a short deck plus a written document rather than one file trying to be both.

Making it

Ettex Slides is where the sequence becomes an actual deck, with speaker notes carrying what you will say rather than the slide carrying it. Two neighbouring pieces cover the parts this one deliberately skips: the visual craft of individual slides is in presentation design, and starting points for common deck types are in slide templates.

Worth being clear about the limits: there is no design assistant that will rewrite your structure, no automatic narrative generation, and no amount of template that substitutes for having decided what the deck is for. The three takeaways are yours to write.
