UX Research Portfolio: How to Show Research That Changed Decisions

In this guide I go through what a research case study should show, how to present methods without drowning the story, and how to handle work under NDA.

What Makes a Strong UX Research Portfolio?

A strong UX research portfolio shows research that changed decisions. Each case explains the question the team needed answered, how you chose the method, what you found and what the team did differently because of it. Methods matter as proof of judgment, and the decision is the headline.

Think of an investigative journalist. Readers care about the sources, and they remember the story that changed something.

The Structure of a Research Case Study

1. The decision at stake: what the team had to decide and why it was uncertain.
2. The research question: one or two questions, written plainly.
3. Method and why: what you chose, with how many participants, and why it fit the time and budget.
4. Key findings: three at most, each with one quote or one data point.
5. What changed: the decision, design or roadmap change, and what happened next.

How to Present Methods Without Losing the Reader

Keep the method to a short block with the essentials: type, participants, duration. Explain the choice in one sentence, for example small usability rounds because, as Jakob Nielsen showed in 2000, five users find about 85% of usability problems. Put the artifacts, such as discussion guides and synthesis boards, in an appendix or a linked page.

Showing Impact and Handling NDA Work

Impact can be a changed decision, a feature the team stopped building or a metric that moved. If the work is under NDA, change the product name, blur sensitive screens and describe the problem and outcome in general terms. Reviewers care about your thinking far more than the brand.

A Quick Review Checklist

• Does each case name the decision the research informed on the first screen?
• Is there at least one real quote or data point per finding?
• Is the method explained in a short block, with the reason for choosing it?
• Does each case end with what changed?
• Is sensitive data removed or anonymized?

Where to Start

Do your research cases open with methods instead of decisions? Does any finding lack evidence? Are you moving into a research or research-heavy design role?
