I can't believe I did it! Passing the ISTQB Usability Testing Certification exam was a huge relief. The Pass4Success practice questions were instrumental in my preparation. There was a tricky question about 'cognitive walkthroughs' and which user tasks should be prioritized during this process. I hesitated a bit but pushed through.

Wow, what a journey it has been! I just passed the ISTQB Usability Testing Certification exam, and I must say, the Pass4Success practice questions were a great help. One question that caught me off guard was about the 'heuristic evaluation' process. It asked how many evaluators are typically recommended for an effective heuristic evaluation. I wasn't entirely sure, but I managed to get through it.

Question #1

You're defining usability test tasks for a web shop for mobile phones and smartphones. Finding out whether users are able to place an order easily has been identified as the main goal of the usability test.

Which of the following is a reasonable task definition to include in the test?

Reveal Solution Hide Solution
Correct Answer: B

A well-defined usability task uses a realistic scenario and goal (''find a suited smartphone within your $200 budget with infrared sensor and order it''), without prescribing exact clicks. This lets you observe how users naturally navigate, search, and complete the order process - directly measuring the main goal of placing an order.


Question #2

Usability reviews aim to identify potential usability problems based on certain criteri

a. Which of the following is a reasonable criterion for a usability review?

Reveal Solution Hide Solution
Correct Answer: D

Usability reviews are grounded in established guidelines, such as ISO 9241-110 or Nielsen's heuristics, that specify how interfaces should behave to support effectiveness, efficiency, and satisfaction. These standards provide objective criteria against which an expert can judge a design's usability.


Question #3

Which of the following is the correct distinction between formative and summative usability evaluation?

Reveal Solution Hide Solution
Correct Answer: C

Formative evaluations are conducted during development to identify and fix usability issues as they arise, guiding iterative design improvements. Summative evaluations are performed after a design is stable to measure its overall effectiveness and compare it against benchmarks or requirements.


Question #4

Which of the following are advantages of using a usability lab?

i. The context is natural

ii. Test sessions are easy to observe

iii. Inexpensive setup
