Multiple choice

What is the primary goal of usability engineering?

  1. To ensure that a product is easy to use

  2. To improve the aesthetics of a product

  3. To reduce the cost of a product

  4. To increase the speed of a product
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The primary goal of usability engineering is to ensure that a product is easy to use, by considering the needs and capabilities of the users and designing the product accordingly.

Multiple choice

Which of the following is NOT a common usability engineering method?

  1. Heuristic evaluation

  2. Cognitive walkthrough

  3. Focus group

  4. A/B testing
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A/B testing is a method for comparing two versions of a product to see which one performs better. It is not a common usability engineering method, as it is more focused on measuring the effectiveness of a product rather than its usability.
