Which attributes define how easily and effectively people can use a product?

• A. Usability attributes
• B. Cognitive processes
• C. Universal design
• D. Simplicity

Answer: (A)

Usability attributes describe how easily and effectively people can use a product. They cover aspects like how quickly a user can learn the interface, how efficiently tasks can be completed, how often errors occur and how easy they are to recover from, and how satisfied users feel during the experience. These attributes are what designers measure and optimize to make an interface intuitive and responsive to real user needs. Cognitive processes refer to the mental steps users take while using a product, universal design is a broader approach aimed at accessibility for people with diverse abilities, and simplicity is about avoiding unnecessary complexity but doesn’t by itself define how usable a product is. In short, usability attributes are the properties that directly define ease of use and effectiveness.
