A strong portfolio does not require an award-winning app, a famous employer, or an enormous project. It needs evidence that you understood a problem, made a decision, and learned from the result. A useful case study might describe a volunteer event you coordinated, a report you improved, or a small system you built for a group.

The challenge is to make ordinary work understandable without exaggerating your impact or revealing someone else’s information. Use the steps below to turn one specific contribution into a short, credible story.

Choose work you can explain and share

Pick a project where you can describe your own decisions. If the work belongs to an employer, client, school team, or community organisation, check permission before showing internal documents, dashboards, screenshots, messages, or names. Removing a logo does not necessarily make material public. When permission is not available, describe the general process with a recreated example clearly labelled as illustrative.

The six-part case study structure

1. Situation: What was happening? Who needed help? Describe the context without unnecessary private details.
2. Constraint: What made the work difficult—limited time, a confusing process, missing instructions, or competing needs?
3. Your role: State exactly what you were responsible for. If it was group work, give credit to collaborators.
4. Decision: Explain one or two choices you made and what alternatives you considered.
5. Result: Say what was delivered or observed. Use verified numbers only when you actually have them.
6. Lesson: Describe what you would repeat, change, or test next time.

Example: improving a volunteer handover

Illustrative example—not a claim about a real organisation: A community event relied on messages scattered across several group chats. A volunteer noticed that people arriving for the afternoon shift did not know where to sign in or which tasks were covered. They created a one-page handover sheet with contacts by role, arrival instructions, and a short task list. After the next event, volunteers said the sheet was easier to follow, but no formal time-savings data was collected.

The portfolio story is not “I revolutionised volunteer operations.” A credible summary is: “I noticed that shift information was fragmented, created a one-page handover template, tested it at an event, and collected informal feedback. Next time I would check instructions with volunteers before finalising the layout.”

Show one piece of evidence

A reader should see something more concrete than adjectives. Depending on permission, you might include a small screenshot of an original public project, an anonymised diagram, a checklist template you created, or a before/after explanation of the decision process. If you cannot share the original artifact, make a demonstration version from scratch and say so.

• Good: “I wrote the briefing, created the scheduling sheet, and facilitated two volunteer check-ins.”
• Too broad: “I led all communications and transformed the entire organisation” when the contribution was narrower.
• Good: “The team adopted the new format for the next event.”
• Unsupported: “The template improved productivity by 80%” without measurement.

Make it easy to scan

Use a short title, a one-sentence summary, and subheadings for the problem, decision, result and lesson. A single case study with a clear contribution is usually more useful than several polished screenshots without context. Explain specialist terms where possible; the reader may not know your industry.

If you are applying for a job, tailor the opening sentence to the kind of work you want to do. For example, an operations role may care about handovers and reliability, while a design role may care about clarity and user feedback. Do not rewrite history to match a role; simply emphasize relevant true details.

A 30-minute drafting exercise

1. Spend five minutes choosing a project that you can publicly discuss.
2. Write one sentence for each of the six case study parts.
3. Identify one shareable artifact or create a clearly labelled demonstration.
4. Ask a trusted person: “What part of my role is still unclear?”
5. Revise for clarity and remove claims you cannot substantiate.
