NEW QUESTION # 13
Which of the following statements about usability test scripts is wrong?
- A. It is a checklist used by the moderator of a usability test.
- B. It contains pre-session interview questions.
- C. It contains answers to the test questions.
- D. It contains post-session interview questions.
Answer: C
Explanation:
A usability test script is a structured document used by the moderator to ensure consistency across test sessions. It typically includes pre-session briefing text, pre- and post-session interview questions, and the specific usability tasks to be performed. However, it does not include answers to the test questions, as usability tests focus on observing user behavior and performance-not testing users' knowledge. Providing answers would bias results and invalidate findings. Thus, option D is incorrect and the best choice.

NEW QUESTION # 14
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
iv. Similar conditions for all sessions
v. Easy recording of sessions
- A. ii & iv are true, i, iii & v are false
- B. iii, iv & v are true, i & ii are false
- C. i, ii & v are true, iii & iv are false
- D. ii, iv & v are true, i & iii are false
Answer: D
Explanation:
Usability labs provide a controlled environment that offers several advantages for observing and recording usability test sessions. Specifically, they allow for easy observation of participants (ii), standardized conditions for each session (iv), and facilitate audio and video recording for detailed analysis (v). However, the context is not natural (i), because the lab is an artificial setting rather than the user's actual environment.
Also, setting up a professional usability lab is not inexpensive (iii); it typically involves significant costs for equipment, space, and staffing. Therefore, options ii, iv, and v are true, while i and iii are false.

NEW QUESTION # 15
A "usability requirement" is:
- A. A requirement how to conduct a usability test
- B. A requirement needed for a usability tester
- C. A requirement needed to define the size of a mobile phone used in a usability test
- D. A requirement on the usability of a component or system
Answer: D
Explanation:
A usability requirement specifies how usable a product or component must be, often in terms of effectiveness, efficiency, and user satisfaction, as defined in ISO 9241-11. These requirements ensure that the product meets specific human-centered design goals, such as allowing users to complete tasks accurately and quickly.
Options A and C describe procedural or test setup elements, not actual usability requirements. Option B refers to personnel qualifications, which are not the same as usability requirements related to system behavior or performance.

NEW QUESTION # 16
In the last project, the usability tests substantially exceeded the budget of the test plan. Which quality control task could have been used to avoid this?
- A. Check consumed resources regularly and compare with the estimates
- B. Check that findings are communicated to the stakeholders
- C. Check that the usability test plan has been properly reviewed
- D. Check whether the usability test report conforms to the best practices
Answer: A
Explanation:
To prevent usability testing from exceeding budget, active monitoring and control of project resources are critical. The best practice is to regularly check consumed time, costs, and effort against the original estimates, allowing timely adjustments to scope or resources. This is a classic quality control practice aligned with ISO
9001 principles and standard project management methodologies. Option A relates to test preparation, option C concerns reporting and communication, and option D applies after test execution. Only option B deals directly with budget control during the test.

NEW QUESTION # 17
As an expert for usability, you're in charge of the usability part of the development of a business application for a large customer. You have worked as a usability expert with the development team for two years and are operating well together; the developers value your feedback and give their bests implementing your suggestions. The product is in an early stage, so there's only a rudimentary prototype available.
Given this information, what is the best approach to verify the usability at the current stage?
- A. Unmoderated usability test
- B. Usability review
- C. Usability maturity assessment
- D. Usability test in the lab
Answer: B
Explanation:
At an early development stage where only a rudimentary prototype exists, a usability review (e.g., expert or heuristic review) is the most effective method. It allows usability specialists to identify potential usability issues without the need for a fully functioning product. Reviews can provide immediate, actionable feedback to guide design improvements before moving into more resource-intensive usability testing. An unmoderated usability test (B) or lab test (D) may be impractical at this stage due to limited interactivity. A usability maturity assessment (C) evaluates organizational processes and is not applicable to evaluating a specific prototype.

NEW QUESTION # 18
What location is NOT suitable for conducting a usability test?
- A. A room at the place where the test participant lives or works.
- B. A public place, such as a cafe.
- C. A room where no action of the user can be seen or recorded by any means.
- D. Two office rooms that are connected by a video link.
Answer: C
Explanation:
The primary goal of usability testing is to observe and record user behavior while interacting with the system.
A location where user actions cannot be seen or recorded (option A) completely undermines the test's purpose and is therefore not suitable.
While options B, C, and D are not ideal in all cases, they can still be valid settings depending on the context.
Testing in a user's natural environment (B) increases ecological validity. Remote testing via video link (C) is widely accepted. Testing in a public setting (D) can be useful for mobile apps or services intended for real- world use.

NEW QUESTION # 19
A company distributes its products over a web shop where users can put items in their shopping cart. After they click on "checkout", the checkout process starts and users cannot go back anymore to correct possible mistakes. The only way is to hit the "back" button of the browser, which might lead to an expired session and therefore losing all items in the shopping cart.
Which of the following heuristics would best describe this usability issue?
- A. Aesthetic and minimalist design
- B. User control and freedom
- C. Visibility of system status
- D. Help and documentation
Answer: B
Explanation:
The described issue violates the usability heuristic "User control and freedom," as defined by Jakob Nielsen.
This principle emphasizes that users should have the ability to undo and redo actions and navigate freely without being trapped in irreversible sequences. In the scenario, users are forced into the checkout process without a clear way to return or correct mistakes, except through the unreliable and disruptive back button.
This design flaw undermines user autonomy and can result in lost progress or frustration.

NEW QUESTION # 20
Which of the following statements about usability test plans is true?
- A. It should contain the briefing instructions
- B. It contains a schedule
- C. It should be very elaborate and at least 10 pages
- D. It contains the results of the test sessions
Answer: B
Explanation:
A usability test plan is a foundational document created before conducting usability testing. It outlines the objectives, scope, methodology, participants, tasks, and schedule for the testing activities. One of its essential components is the schedule, which details when and how test sessions will occur to ensure proper resource allocation and time management. Including a schedule helps coordinate between test moderators, participants, observers, and stakeholders, making the testing process organized and efficient.
While briefing instructions (Option B) may be related to the usability test, they are typically documented separately or included in participant materials rather than the formal test plan itself. The test plan should be concise and focused; it need not be overly elaborate or lengthy (Option C), as clarity and usability of the plan are more important than length. The results of the test sessions (Option D) are not included in the test plan but rather compiled afterward in a test report or analysis document.
Therefore, the correct statement is that the usability test plan contains a schedule, ensuring a structured timeline for the usability testing activities.

NEW QUESTION # 23
What is a usability test task?
- A. A usability test execution activity specified by the moderator that needs to be accomplished by a usability test participant within a given period of time
- B. A document specifying a sequence of actions for the execution of a usability test. It is used by the moderator to keep track of briefing and pre-session interview questions, usability test tasks, and post- session interview questions
- C. A test session in usability testing in which a usability test participant is executing tests, moderated by a moderator and observed by a number of observers
- D. A process through which information about the usability of a system is gathered in order to improve the system (known as formative evaluation) or to assess the merit or worth of a system (known as summative evaluation)
Answer: A
Explanation:
A usability test task is a clearly defined activity that a participant is asked to perform during a usability test session. These tasks are typically created by the test designer or moderator and are designed to reflect realistic user goals (e.g., "Find and buy a product"). The purpose is to observe the participant's interaction with the system and identify usability issues. Option A describes a usability test script, not a task. Option C defines usability evaluation in general, and D refers to a session, not a specific task. Therefore, B is correct.

NEW QUESTION # 24
What is good accessibility?
- A. Good usability regardless of disturbances like bright sunlight, noise or wind
- B. Good usability of a software product by people with limited knowledge of the software
- C. Good usability of a software product on all devices (smart phone, computer, etc.)
- D. Good usability of a software product by people with limited vision, hearing, dexterity, cognition or physical mobility
Answer: D
Explanation:
Accessibility refers to designing products so that people with disabilities or limitations (permanent or temporary) can use them effectively. According to the Web Content Accessibility Guidelines (WCAG) and ISO standards, accessibility focuses on ensuring that users with vision, hearing, cognitive, or mobility impairments can access digital interfaces. Option D captures this intent accurately. The other options relate to general usability or responsiveness (e.g., device adaptability or user experience in noisy environments) but do not address the inclusive nature of accessibility as defined by official guidelines.

NEW QUESTION # 25
Why are positive usability findings of high importance? Which of the following statements is wrong?
- A. Positive usability findings should be used to communicate to the development team which features should not be modified or deleted.
- B. Positive usability findings make it easier to sell the need for correcting usability problems by giving a balanced view.
- C. Positive usability findings allow a better view of the usability of the product.
- D. Positive findings are of high importance because they can be used in the report to justify the costs of the test.
Answer: D
Explanation:
Positive usability findings play a key role in reinforcing what is working well in the user interface. They help:
A: Build developer confidence and soften criticism when pointing out issues.
C: Provide a complete picture of usability strengths and weaknesses.
D: Inform developers what should remain unchanged during redesign.
However, B is incorrect because justifying usability test costs should not rely solely on positive findings. Cost justification should come from the overall impact of usability on user satisfaction, performance, and business outcomes-not just good results.

NEW QUESTION # 26
Which of the following are common mistakes made in usability testing?
i. The user is too active
ii. Critical results are ignored
iii. No observers involved
iv. Scheduling too late
v. Incorrect focus
- A. ii & iv are true, i, iii & v are false
- B. i & iii are true, ii, iv & v are false
- C. ii, iv & v are true, i & iii are false
- D. i, ii & iii are true, iv & v are false
Answer: C
Explanation:
Common mistakes in usability testing include:
Ignoring critical results (ii): A significant issue if findings are not acted upon.
Scheduling the test too late (iv): This can lead to usability problems being discovered too late to be addressed effectively.
Having the wrong focus (v): For instance, focusing on aesthetics instead of usability goals.
Option i ("user is too active") is not a problem-active participation is necessary. Option iii ("no observers involved") is not a typical mistake, since tests can still be valid even with recorded sessions and later review.
Hence, the correct answer is A: ii, iv & v are true.

NEW QUESTION # 27
In a short conversation, a potential customer mentions that accessibility is of great importance to them. What does this mean?
- A. They use prototyping in their development process
- B. They focus on quantitative usability evaluations
- C. They focus on agile development
- D. They also seek to address users with limitations
Answer: D
Explanation:
When a customer emphasizes the importance of accessibility, it means they are concerned with ensuring that users with disabilities or limitations are not excluded from using their products or services. Accessibility is about inclusiveness-providing equal access and opportunity to all users regardless of physical or cognitive ability. Option C directly reflects this understanding. The other options (A, B, and D) are aspects of usability or development methodologies but do not relate to addressing the needs of users with disabilities, which is the core focus of accessibility.

NEW QUESTION # 28
Your project manager asked you for your advice. A recent project failed because the users were not satisfied with the final product, although your project manager claimed that she followed the human-centered design process. She interviewed users at the start of the project, created a first prototype and evaluated that prototype.
Which part of the human-centered design process did she miss?
- A. The "design"-part
- B. The "analyze"-part
- C. The "evaluate"-part
- D. The "iterate"-part
Answer: D
Explanation:
The human-centered design process emphasizes iterative development-testing and refining designs through multiple cycles. In the scenario, the project manager interviewed users and evaluated a prototype but did not iterate based on feedback. Skipping iteration likely resulted in unmet user needs. Human-centered design, per ISO 9241-210, includes: understanding context of use, specifying requirements, producing design solutions, and evaluating-repeated iteratively. Hence, option D ("iterate") is correct.
