NEW QUESTION # 15
Which of the following statements about usability test scripts is wrong?
- A. It contains pre-session interview questions.
- B. It is a checklist used by the moderator of a usability test.
- 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 # 16
You're conducting a user survey and you have reached the third stage, selecting an appropriate questionnaire.
You have decided to use a standardized questionnaire as you want to benchmark against previous usability measurements.
Which of the following user questionnaires allow benchmarking against previous usability measurements?
i. SUS
ii. SUMI
iii. WAMMI
- A. i, ii and iii are true
- B. i is true, ii & iii are false
- C. i & ii are true, iii is false
- D. ii & iii are true, i is false
Answer: A
Explanation:
SUS (System Usability Scale), SUMI (Software Usability Measurement Inventory), and WAMMI (Website Analysis and Measurement Inventory) are all validated, standardized usability questionnaires that support benchmarking. They allow comparison against known usability scores from a wide variety of systems. These instruments provide numeric scores that can be interpreted using benchmark datasets or industry standards.
Therefore, all three-i, ii, and iii-are true, making D the correct answer.

NEW QUESTION # 17
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. i, ii & iii are true, iv & v are false
- D. ii, iv & v are true, i & iii are false
Answer: D
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 # 18
The usability team has written a usability test report. The report has the following structure:
Executive summary (1 page)
Table of contents (1 page)
Findings and recommendations (5 pages)
Objectives (2 pages)
Purpose (2 pages)
Contacts (1 page)
Which best practice does this usability test report violate?
- A. The report misses positive findings
- B. The report is too long
- C. The report makes use of usability jargon
- D. The report misses a description of the evaluation method
Answer: D
Explanation:
A best practice in usability reporting (based on ISO/IEC 25062:2006 - Common Industry Format for usability test reports) is to include a clear description of the evaluation method used. This includes how the test was designed, how participants were selected, what tasks were performed, and under what conditions the test was conducted. This ensures the results are credible and reproducible. The provided structure omits this essential information. While the report length is not excessive and positive findings may or may not be present, the key missing component is the method description.

NEW QUESTION # 19
Which of these basic approaches to a software development project follows all key elements of human- centered evaluation?
- A. Interview users, develop the software, and perform acceptance test
- B. Define requirements, develop the software, and perform acceptance test
- C. Iteratively develop prototypes, perform expert reviews, and integrate found issues
- D. Interview users, iteratively develop prototypes, and evaluate the software
Answer: D
Explanation:
Human-centered design, as defined by ISO 9241-210, emphasizes early user involvement, iterative design, and continuous usability evaluation. Option D aligns with this model as it begins with understanding user needs (interview users), proceeds through iterative prototyping (which allows for continuous improvement), and involves user evaluation. This ensures that the final product is shaped by real user input and feedback.
Options A and B lack iteration and continuous evaluation, while option C, although partially aligned, lacks explicit user involvement in the evaluation process, focusing only on expert reviews.

NEW QUESTION # 21
Usability reviews aim to identify potential usability problems based on certain criteria. Which of the following is a reasonable criterion for a usability review?
- A. Statutory Code of Practice
- B. Usability standards
- C. Opinion of the management
- D. Functional requirements
Answer: B
Explanation:
Usability reviews evaluate a system or interface against established usability principles or standards to identify potential issues before user testing. A recognized criterion for such reviews includes adherence to usability standards such as ISO 9241 or the Web Content Accessibility Guidelines (WCAG). These standards are derived from years of research and user-centered design principles. Options A and C do not directly relate to usability. Functional requirements (option B) refer to what the system should do, not how usable it is.
Hence, option D is correct as usability standards provide a consistent, objective basis for evaluating usability.

NEW QUESTION # 22
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. iii, iv & v are true, i & ii are false
- B. ii & iv are true, i, iii & v 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 # 23
A "usability requirement" is:
- A. A requirement needed for a usability tester
- B. A requirement how to conduct a usability test
- 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 # 24
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 "analyze"-part
- B. The "iterate"-part
- C. The "design"-part
- D. The "evaluate"-part
Answer: B
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.

- A. Check that findings are communicated to the stakeholders
- B. Check whether the usability test report conforms to the best practices
- C. Check consumed resources regularly and compare with the estimates
- D. Check that the usability test plan has been properly reviewed
Answer: C
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 # 26
How can the approach for conducting user surveys be summarized best?
- A. Write survey plan, write schedule, select questionnaire, recruit users, analyze, communicate
- B. Write survey plan, interview users and stakeholders, select questionnaire, recruit users, remind users, communicate
- C. Write survey plan, write schedule, select questionnaire, recruit users, remind users, communicate
- D. Write survey plan, interview users and stakeholders, select questionnaire, deploy questionnaire, analyze, communicate
Answer: D
Explanation:
Conducting user surveys involves a structured approach that ensures data collection is effective, reliable, and meaningful. The process typically starts with writing a survey plan, which defines the objectives, scope, target population, and methodology. Next, interviewing users and stakeholders is important to gather qualitative insights, refine survey questions, and align the survey with business goals and user needs.
Selecting or designing the questionnaire follows, which includes crafting clear, unbiased questions to capture the desired data. After that, deploying the questionnaire to the recruited participants is essential; this can be done via email, online tools, or in-person, depending on the context. Once the data is collected, it must be analyzed to extract meaningful patterns, trends, and insights. Finally, communicating the findings to stakeholders completes the process by informing decision-making.
Other options miss critical steps such as deploying the questionnaire (Option C), or combine steps incorrectly (Options A and D). Importantly, the step of interviewing users and stakeholders prior to deployment ensures the survey is well-informed and targeted, enhancing the quality and relevance of data collected.

NEW QUESTION # 27
What is good accessibility?
- A. Good usability of a software product by people with limited knowledge of the software
- B. Good usability of a software product by people with limited vision, hearing, dexterity, cognition or physical mobility
- C. Good usability of a software product on all devices (smart phone, computer, etc.)
- D. Good usability regardless of disturbances like bright sunlight, noise or wind
Answer: B
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 # 28
Which of the following is the correct distinction between formative and summative usability evaluation?
- A. Summative evaluations mostly rely on experts, formative evaluations require users
- B. Summative evaluations focus on improvement, formative evaluations assess the outcome
- C. Summative evaluations mostly rely on user tests, formative evaluations require experts
- D. Summative evaluations assess the outcome, formative evaluations focus on improvement
Answer: D
Explanation:
Formative usability evaluation is conducted during the development process to identify usability problems and improve the product iteratively. It is diagnostic and improvement-focused. Summative evaluation, on the other hand, is done after development to assess the final product's usability, measuring how well it meets defined usability goals. Therefore, the correct distinction is that formative evaluation focuses on improvement, and summative evaluation assesses the outcome. This distinction aligns with widely accepted models such as those defined by ISO 9241-210 and usability.gov.

NEW QUESTION # 29
Which of the following statements about usability testing is true?
- A. The conditions under which a usability test is done are irrelevant
- B. The preparation of a usability test is optional
- C. A usability test consists of one usability test session
- D. Before the usability test sessions, a pilot usability test session can be conducted
Answer: D
Explanation:
A pilot usability test session is a critical step prior to conducting the actual usability test. Its purpose is to ensure that the test setup, task design, and moderator instructions are clear and function as expected.
According to ISO 9241-210 and the Nielsen Norman Group's best practices, pilot testing helps detect unforeseen issues and fine-tune the process. Options A and B are incorrect because testing conditions must reflect realistic scenarios, and thorough preparation is essential to gather meaningful usability data. Option D is also incorrect; a usability test typically consists of multiple sessions with different users to gather sufficient data for analysis. The pilot session ensures everything works smoothly before involving real participants.

NEW QUESTION # 30
Why are positive usability findings of high importance? Which of the following statements is wrong?
- A. Positive usability findings make it easier to sell the need for correcting usability problems by giving a balanced view.
- B. Positive usability findings allow a better view of the usability of the product.
- C. Positive findings are of high importance because they can be used in the report to justify the costs of the test.
- D. Positive usability findings should be used to communicate to the development team which features should not be modified or deleted.
Answer: C
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.
