What is the purpose of usability test reports in UID practice?

• A. They list code changes
• B. They document findings and inform design decisions
• C. They reflect marketing feedback
• D. They are optional artifacts

Answer: (B)

The purpose of usability test reports in UID practice is to document findings and inform design decisions. These reports capture how real users interact with the interface, where they struggle, what tasks are easy or confusing, and how long tasks take, then translate those observations into actionable insights. By organizing issues with severity and providing concrete recommendations and priorities, the report guides designers on what to change first and how to improve the user experience in the next iteration. This turns raw test data into data-driven design updates that enhance usability.

They aren’t about listing code changes or reflecting marketing feedback, and in practice they’re not optional; they’re the primary vehicle for communicating user issues and backing design choices with evidence.
