How to storyboard a presentation before you build a single slide

What a presentation storyboard is

A presentation storyboard is a sketch of the whole deck before any slide is built: one box per slide, each holding the point the slide will make and the evidence it will use. The term comes from film, where a storyboard shows each shot in sequence. For a presentation the drawing matters less than the words. The box does not need a picture; it needs a sentence.

A storyboard differs from an outline in one way that matters. An outline lists topics: “Market”, “Competitors”, “Pricing”. A storyboard states what each slide will claim and what will prove it, in the order the audience will see it. You can read a storyboard as an argument. You can only read an outline as a table of contents.

Why storyboard first

• Changes are cheap. Moving a box takes seconds; rebuilding six designed slides takes an afternoon.
• You see the whole argument at once, so gaps, repeats and detours show up before the audience finds them.
• It separates thinking from formatting. Fonts and layouts wait until the content is settled.
• Others can review it early. A manager or client can agree the storyline in ten minutes, before anyone builds a chart.
• It shows what work is left. A box whose evidence reads “to find” is a task with a clear purpose.

Fix the argument while it is cheap. Every hour spent designing a slide that is later cut is an hour a storyboard would have saved.

The five-step method

1. Write the answer in one sentence. What should the audience believe or do when you finish? “Approve the new call-routing system” is an answer; “an update on customer service” is not.
2. List the three to five points that support it. These are the reasons the audience should accept your answer, and they become the sections of the deck. Our guide to the Pyramid Principle covers how to group and order them.
3. Draw one box per slide. In each, write the slide's point as a full-sentence title and note the evidence it needs: a chart, a number, a quotation, a photograph or an example.
4. Read the titles in sequence. Read only the titles, aloud, from first to last. Fix any point that does not follow from the one before, and cut any box that does not move the argument forward.
5. Only then design. Build the slides from the boxes, one at a time, with each title already written and its evidence already chosen.

Most of the value sits in steps 2 and 4. Step 2 forces you to decide what the presentation argues before you decide what it contains. Step 4 is the test: if the titles read like a short memo, the presentation works; if they read like a list of topics, no design will save it.

What goes in each box

• The title: the point the slide makes, as a sentence of about 15 words or fewer. Our guide to action titles covers how to write these.
• The evidence: what will prove the title. Be specific: “line chart of monthly wait times, 2024–2026” rather than “data”.
• The source: where the evidence will come from, and whether you have it yet.
• The talking point: one line on what you will say that is not on the slide.
• Optionally, a rough sketch of the layout, if a diagram or a side-by-side comparison matters to the point.

Keep each box to these few lines. A storyboard that holds full slide text has turned into a draft deck, and it loses the speed that makes it worth doing.

Paper, sticky notes or a blank deck

• Paper: a sheet folded into eight or twelve boxes, or a printed grid. Fast, and good for working alone.
• Sticky notes on a wall or whiteboard, one per slide. Best for teams, because anyone can move a note and everyone sees the whole storyline at once.
• A blank deck: one empty slide per box, with only the title typed in and the evidence noted in the body. Read the sequence in the slide sorter view. Consultants call this version a ghost deck, and it turns straight into the real presentation.
• A numbered list in a document: titles as items, evidence as sub-points. Easy to share for comments, though harder to rearrange at a glance.

The format matters less than the discipline. Whatever you use, the titles must be sentences and every box must name its evidence.

Example: storyboarding a budget request

The head of customer service at an insurance company wants funding for a new call-routing system. She has 15 minutes with the leadership team. Her first storyboard has six boxes, each with a title and the evidence it needs. The numbers are illustrative.

• Box 1: Fund a $260K call-routing system to halve customer wait times by October
• – Evidence: two key numbers, today's 11-minute average wait and the 5-minute target
• Box 2: Average wait times have doubled to 11 minutes since 2024
• – Evidence: line chart of monthly wait times, 2024–2026, from the phone system
• Box 3: Long waits are costing us renewals
• – Evidence: renewal rates by wait time, from the CRM
• Box 4: Half of all calls reach the wrong team first and are transferred
• – Evidence: transfer data, still to request from IT
• Box 5: Skills-based routing sends calls to the right team first and pays back in 18 months
• – Evidence: vendor benchmarks and our own cost model
• Box 6: Decision needed: approve the budget this month to be live before the renewal season
• – Evidence: timeline with the vendor's 16-week lead time

Reading the titles aloud, she noticed that box 3 claimed more than her data showed. The CRM showed that customers who waited longer renewed less often, but not that the wait was the cause. She rewrote the title as “Customers who waited over 10 minutes renewed 9 points less often”, which the chart could support. On paper the change took a minute. In the meeting, the original claim would have been the first thing the finance director challenged.

Common mistakes

• Storyboarding topics instead of points: boxes labeled “Background” and “Data” rather than sentences.
• Writing full slide text in every box, which turns the storyboard into a slow first draft.
• Skipping the read-through, which is the step that finds the problems.
• Treating the storyboard as fixed. When the analysis says something different, change the box.
• Starting from the evidence you happen to have rather than the evidence the argument needs.
• Planning more boxes than the time allows. As a rule of thumb, budget about one main slide a minute, and fewer for slides with charts.

Storyboard checklist

• Is the answer written as one sentence the audience could accept or reject?
• Are there three to five supporting points, each of which becomes a section?
• Does every box have a full-sentence title?
• Does every box name its evidence and where it will come from?
• Read aloud in order, do the titles make the argument?
• Does the number of boxes fit the time slot?
• Has someone else read the titles before you started designing?
