Which usability attribute asks how easy (or hard) is it for users to perform basic tasks the first time they use the product?

• A. Learnability
• B. Efficiency
• C. Memorability
• D. Satisfaction

Answer: (A)

The concept being tested is how easy it is for a brand-new user to perform basic tasks on first use. Learnability measures how quickly someone can learn to accomplish these tasks with minimal guidance. When a product has high learnability, a first-time user can sign in, find what they need, and complete simple actions without heavy instruction, making the initial experience smooth and frustration-free. The other attributes describe different ideas. Efficiency looks at how fast and accurately tasks can be completed once a user has learned them, memorability focuses on how well a user remembers how to use the product after a period of not using it, and satisfaction covers the overall enjoyment and comfort with the product. None of these capture the immediate ease a new user experiences when performing basic tasks for the first time.
