Which role is most likely to verify that a site design works for users through testing?

• A. usability expert
• B. strategist
• C. project manager
• D. designer

Answer: (A)

Verifying that a site design works for users through testing is the work of a usability expert. They specialize in how people interact with an interface and design and run usability tests with representative users, guiding tasks, observing behavior, and collecting metrics like task success, time on task, error rates, and satisfaction. This focus helps uncover where users stumble, what parts are confusing, and how the flow can be improved before launch, ensuring the design is intuitive and efficient in real use. Other roles may contribute to testing in various ways—strategists shape goals and expectations, project managers coordinate timelines, and designers refine visuals and interactions—but the Usability Expert is the one whose primary responsibility is validating usability through structured testing.
