A credible case study distinguishes what was built, what was observed and what remains unmeasured. Visuals should support a confirmed scope and accurately describe the team's role.
Collect verifiable material
For a fictional operations portal, gather the initial problem, product decisions, approved screens and acceptance scenarios. If commercial impact has not been measured, describe the delivery without assigning assumed growth to it.
| Claim | Evidence to obtain |
|---|---|
| Delivered capability | Identifiable version and demonstrable scenario |
| Observed improvement | Method, period and comparison baseline |
| Testimonial | Approved wording and publication permission |
| Screenshot | Usage rights and redacted customer data |
State the boundaries
Explain the team's actual contribution and external dependencies. Design involvement does not imply ownership of the entire platform. Avoid percentages without denominators and comparisons between incompatible periods.
What can be published without business metrics?
A process case study can still explain the problem, trade-offs, delivered scope and current state. Label mockups and illustrations clearly. Add results later when supporting evidence exists. The reader should know whether the example demonstrates design reasoning, technical delivery or measured commercial performance rather than having to infer that distinction.
Do not generalise a regional outcome globally
If a result was measured for one team or market, state that scope. An English case study can reach a broader audience without implying that the same outcome was observed everywhere. Keep the original measurement context visible when adapting the narrative.
