A shared creative project can make a strong case study. Explain your contribution precisely enough that a buyer can see your judgment, your responsibilities and the work of the other people involved.
If the case study also reports leads, opportunities or payments, check what the results records actually support. The ledger below identifies each contributor's work; the results guide separates reported events, customer journeys and causal claims.
Choose the contribution you want to demonstrate
Start with the service a future buyer might hire you to provide. If that service is page design, the useful story may be how your team translated a difficult brief into a usable page structure. You do not need to take credit for the entire launch to explain that decision well.
Write a provisional sentence: “Our team designed the landing page and its component system for a launch led by the client's marketing team.” Then check each part against the work records. Who made the original design decisions? Who adapted them? Who approved the result? Who can confirm those answers?
A client logo, invoice or screenshot does not answer all four questions. An invoice can establish a commercial relationship while saying little about who developed the central idea. A screenshot can show the finished page while concealing everyone who contributed to it.
Complete a contribution ledger before writing the story
The following project, records, permissions and decisions are fictional teaching examples. They describe no real client or agency. Example Studio is preparing a portfolio page about a shared launch for Example Client.
| Work shown | Actual contribution | Record and verifier | Illustrative publication decision |
|---|---|---|---|
| Positioning and page copy | Client marketing team set the proposition and supplied the approved copy | Dated client brief; client marketing lead confirms authorship | Credit the client; Studio may explain how it used the brief |
| Landing-page design | Studio created the wireframes, page layout and reusable components | Versioned design file and review notes; client design lead confirms scope | Show the approved design screens and describe Studio's decisions |
| Page build | An independent developer implemented Studio's design | Build handoff and developer confirmation | Name the developer with permission; describe Studio's design support without claiming the build |
| Hero photography | A photographer commissioned by the client created the images | Image delivery record; client producer confirms commission | Credit the photographer; omit the photographs because portfolio-use permission is unresolved |
| Icon set | Client's existing brand agency supplied the icons | Brand-asset guide and original file credits; client brand lead verifies source | Identify them as supplied brand assets; use only the specifically approved icons |
In this example, the client has approved the exact page copy, logo and selected design screens for Studio's website. The developer and brand agency have approved their credits. The selected screens use an approved plain image placeholder instead of the unresolved hero photography. The caption explains that substitution; the image is presented as a design view, not a screenshot of the live page.
For your own ledger, keep the actual source file, verifier, approval date and permitted uses beside each row. “The client approved the case study” is too broad to settle whether a particular image or third-party name can appear in a paid advert later.
Turn the ledger into a page a buyer can understand
The fictional team rejects this heading:
We designed and built every part of the launch.
It chooses:
Landing-page design for a client-led launch.
Its opening paragraph reads:
Example Studio designed the page structure, layout and reusable components from Example Client's positioning and copy. An independent developer built the page. The client supplied photography and an existing icon set; the credits below identify their creators.
The rest of the page can now go deep on Studio's contribution: a difficult content hierarchy, the options considered, the client's feedback and the resulting design. Label images with the work they demonstrate. Keep the credit near the first image or description that would otherwise suggest sole authorship.
A small credit at the bottom should not have to undo an expansive headline at the top. The UK's CAP Code on misleading advertising considers the overall impression, requires evidence for objective claims and addresses significant qualifications. The ledger above is an editorial method for checking your wording; it is not a form prescribed by CAP.
Deal with the awkward cases directly
A founder did the work at a previous employer. State the person's creative role and the organisation under which the work was delivered. Verify the right to show it. Do not present it as a project won or delivered by the new agency.
A subcontractor did most of the specialist work. Explain what your agency owned: perhaps art direction, briefing or design integration. A buyer can assess those responsibilities when you describe them clearly.
The client says you were wonderful. Keep an approved, genuine testimonial within the scope of the speaker's experience. Praise does not establish authorship of every deliverable, ownership of the assets or a right to publish someone else's work.
A contributor disputes a row. Hold the affected claim and image while you resolve the source records and proposed credit. You can continue preparing the undisputed sections without releasing a misleading account.
Make one specific release decision
In the fictional example, the design case study can proceed with the stated approvals, credits and clearly labelled design views. The claim to have designed and built everything cannot. The unresolved photographs remain excluded.
Before your next portfolio update, take one proposed headline to the people who can verify the creative work. Complete the ledger, replace disputed or unsupported wording and approve the exact page together. The finished story should let a prospective client explain what your agency did after reading its opening paragraph.
Keep the source and approval for each proposed statement in the claims and evidence register. If this is still a possible project, use the customer-story opportunity worksheet to separate public observations from hypotheses and choose the next question. It does not confirm buying intent or permission to publish.
