Which term describes the extent to which a product or system can be used effectively, efficiently, and satisfactorily by users to achieve their goals?

• A. Usability
• B. Precision
• C. Context
• D. Ambiguity

Answer: (A)

Usability describes how well a product or system supports people in using it to achieve their goals. It captures three key ideas: effectiveness (can users achieve their tasks accurately and completely?), efficiency (how much effort or time does it take?), and satisfaction (do users feel comfortable and pleased with the experience?). These aspects come together in common standards like ISO 9241-11 to define overall usability. A product with high usability lets a user accomplish tasks quickly with few errors and minimal effort, while also providing a pleasant experience. That’s why this term is the best fit for the description in the question. Precision focuses on accuracy or exactness of measurements or outcomes, not on how people interact with a product. Context refers to the environment or conditions in which something is used, which can influence usability but isn’t the measure itself. Ambiguity means unclear or confusing information, which would harm usability but is not a term that describes the overall ability to use a product effectively.
