Free CUA Usability Testing & Evaluation Techniques Questions and Answers

Question 1

What is usability testing?

Accepted Answer

Evaluating with users

Answer

Usability testing is a method for evaluating a product or system by testing it directly with representative users. The goal is to observe how users interact with the product, identify any difficulties they encounter, and gather feedback to improve its ease of use and overall user experience. This direct evaluation is critical for creating effective and user-friendly designs.

Question 2

Which metric measures ease of use in usability testing?

Accepted Answer

Task success rate

Answer

Task success rate is a key metric in usability testing that measures the percentage of users who successfully complete a given task without significant issues. A higher success rate indicates better ease of use and a more intuitive design. This metric directly reflects how effectively users can achieve their goals with the product, making it a direct measure of usability.

Question 3

What is the purpose of a heuristic evaluation?

Accepted Answer

Identify usability issues

Answer

A heuristic evaluation is an expert-based method for identifying usability problems in a user interface design. Evaluators assess the interface against a set of established usability principles or 'heuristics' to pinpoint areas where users might encounter difficulties. Its primary goal is to uncover these issues early in the design process.

Question 4

What does 'think aloud' protocol involve?

Accepted Answer

Verbalizing thoughts

Answer

The 'think aloud' protocol is a user research method where participants are asked to continuously speak their thoughts aloud while interacting with a system. This technique allows researchers to understand the user's mental model, decision-making process, and identify points of confusion or difficulty directly from their verbalized experience.

Question 5

Why is usability testing iterative?

Accepted Answer

Repeated testing improves UX

Answer

Usability testing is inherently iterative because it involves conducting multiple rounds of testing, analyzing the results, making design improvements, and then re-testing the updated design. This cyclical process allows designers to identify and fix usability issues progressively, leading to a continuously refined and improved user experience.
