How to Make a Case Study Presentation

A case study presentation is the slide version of a case study: a focused narrative about one real customer or project, built around a before-and-after arc. Instead of telling an audience your product or service works, it shows a specific instance where it did, with a specific challenge, a specific approach, and specific numbers attached to the outcome. That specificity is the entire point. A case study without real detail is just a testimonial with extra slides.

It shows up in more places than most people expect. Sales teams use it mid-funnel, once a prospect has moved past the first pitch and wants proof from someone in a similar situation. Marketing teams publish it as gated content or a webinar. Consultants and agencies build one after every engagement, both to close out the project internally and to reuse externally as a credibility asset. Customer success teams use it internally to show renewal and expansion stakeholders what's working.

It's easy to blur with a testimonial or a sales deck, but the job is different. A testimonial is a quote; a case study is a narrative with a beginning, middle, and end, built around real detail. A sales deck argues for why a prospect should buy; a case study proves it already worked for someone else, then lets the reader draw their own conclusion.

Most effective case study presentations follow a version of the same story arc, whether the final deck runs six slides or fifteen. Use the outline below as a working structure, then adjust depth to match how the deck will be used.

1. Cover slide. Client name and logo (with permission), plus a one-line headline that states the result, not just the topic. "How [Client] cut onboarding time by 60%" earns more attention than "[Client] Case Study."

2. Executive summary. The whole story compressed into one slide: the challenge, the solution, and the headline result. This is the slide a skimmer reads before deciding whether to keep going, so it has to work standing alone.

3. About the client. Who they are, their industry, size, and relevant context, only as much as the audience needs to understand why their situation is credible and relatable to their own.

4. The challenge. The specific problem the client faced before working with you, described in their language and with their stakes, not yours. Name what wasn't working and what it was costing them, in time, money, or risk.

5. The approach. How the problem was addressed: the process, methodology, or key decisions made along the way. This is where you show the thinking, not just the outcome, which is often what a prospect evaluating you cares about most.

6. The solution. What was actually delivered or implemented: the product, service, or specific changes made. Keep this concrete and grounded in what happened, not a generic feature list.

7. Results and metrics. The measurable outcome, ideally two or three hard numbers with a clear before-and-after: time saved, revenue gained, cost reduced, error rate dropped. This is usually the slide that does the most convincing, so give it real visual weight.

8. Client quote or testimonial. A direct quote, attributed by name and title, that reinforces the result in the client's own words. A specific quote about the result beats a generic one about how nice the team was to work with.

9. Visual proof (optional). A dashboard screenshot, a before-and-after chart, or a timeline of the engagement, whatever gives the audience something concrete to look at beyond text.

10. Key takeaway and next step. What this story proves more broadly, and a clear call to action: read another case study, book a call, or start a trial.

The most common quality gap in a case study presentation is a challenge slide that's vague while the results slide is specific. "The client needed a better way to manage their workflow" tells the reader nothing; "the client's team spent 12 hours a week manually reconciling spreadsheets across three departments" tells them exactly what was broken and sets up the result that follows. Match the level of specificity on the challenge slide to the level of specificity on the results slide, or the story reads as unbalanced.

Numbers do more work than adjectives everywhere in this deck, but especially on the results slide. "Significant improvement" is forgettable; "reduced onboarding time from six weeks to nine days" is not. If a number exists, put it on the slide. If it doesn't exist yet, that's worth flagging internally before publishing the case study, because a results slide without a hard number is the weakest slide in the deck.

Keep technical implementation detail, if any exists, out of the main narrative and in an appendix instead. A prospect evaluating whether to work with you cares about the challenge, the approach, and the result; a technical buyer doing deeper diligence might want the implementation detail, so hold it in reserve rather than slowing down the main story with it.

The strongest case studies make the client the hero of the story, not the vendor. That means opening on their situation and their stakes before you introduce what you did, and describing the challenge in language the client themselves would recognize and repeat, not internal terminology from your own product. A reader should see their own situation reflected in the challenge slide before they ever get to your solution.

Specificity beats polish at every step. A results slide with two hard numbers and a plain chart is more convincing than one with five vague claims and a stock photo. If you only have one strong metric, lead with that one and don't pad the slide with softer claims to make it look fuller; padding usually makes a strong result look weaker by association.

A direct quote does work that narration can't. Whenever possible, get the client's own words about the specific result, not a generic compliment about the relationship, and attribute it by name and title. "They're a great partner" is filler; "we went from a two-week close process to same-day approval" attributed to the actual VP who lived it is proof.

End on a takeaway that generalizes, not just a recap. The best last slide connects this one client's result to what it suggests for a reader in a similar situation, then gives them one specific next step, rather than simply restating the summary a second time.

The most common mistake is publishing a case study built around impressions instead of numbers. "The client saw great results" is not a case study; it's an assertion asking to be trusted on faith. If the underlying data doesn't support a hard number yet, it's worth waiting until it does rather than shipping a results slide that undercuts the story's credibility.

A close second is making the story about the vendor's process instead of the client's outcome. It's natural to want to showcase your own methodology in depth, but a reader evaluating whether to work with you cares far more about what happened to a company like theirs than about the internal steps you took to get there. Keep the approach slide brief and let the results slide carry the weight.

Dense, uncredited text is another recurring problem: paragraphs copied from a written case study report, dropped onto slides with no attribution and no visual break. A slide needs to be absorbed in seconds, so pull the one number and one sentence that matter most onto the slide itself, and keep the rest as supporting narration or notes you keep alongside the content.

The last common gap is no next step. A case study that ends on the results slide, or fades out after the client quote, leaves the reader to figure out on their own what to do with what they just read. Always close with a clear, specific call to action, whether that's contacting sales, reading a related case study, or booking a demo.

You don't have to start from a blank slide or a locked layout. In Eazy, draft the story from a prompt, or bring in a source you already have (a written case study PDF, an internal Word report, or notes from the account team), and it's read into real, editable content you can shape right away: headings, bullets, and slide dividers, not a fixed grid you have to fight.

Work through the story arc above section by section inside the document: write the challenge, describe the approach, list the results under a clear heading, paste the client quote where it belongs. Because the document is the source of truth, you're always editing the actual narrative, not rearranging boxes on a canvas. You can also keep your own notes on sourcing or approvals alongside the content as you build.

Once the story is right, apply a theme to design the whole deck at once: every slide arrives designed and on-brand, with no manual formatting required. If a result gets updated or a new metric comes in later, change that one line and only that slide rebuilds, so the rest of the case study stays untouched.

Add your own logo and client-approved images, or generate an image inline for a slide that needs one, then export the finished case study presentation to PDF for a leave-behind or PPTX to keep working in PowerPoint. Eazy is free during early access, with credits included and no watermark on exports.
