NEW QUESTION # 19
A web shop owner used Google Analytics to gather information about her users. She found out that most users take about five minutes to place an order. Is the usability of the website good or bad?
- A. That depends on the context of use as users may have different expectations
- B. The usability of the website is good - five minutes is a fair amount of time
- C. That depends on the accessibility of the website
- D. The usability of the website is bad - five minutes is way too long
Answer: A
Explanation:
Usability is defined in ISO 9241-11 as the extent to which a system can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use. Without knowing the context-such as product complexity, user familiarity, device type, or purchasing habits-it is impossible to judge whether five minutes is good or bad. For complex items, five minutes may be reasonable, while for one-click purchases, it may be excessive. Thus, usability cannot be assessed solely based on one metric like time-it must be evaluated within its full usage context.

NEW QUESTION # 20
Which of the following statements about usability test plans is true?
- A. It contains a schedule
- B. It should contain the briefing instructions
- C. It contains the results of the test sessions
- D. It should be very elaborate and at least 10 pages
Answer: A
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 # 21
What's the difference between an informal usability review and an expert usability review?
- A. No formal usability qualifications are required for an informal usability review
- B. An expert usability review is a formal review, not an informal review
- C. Contrary to an expert review, an informal usability review is based on opinion
- D. An informal review only requires one reviewer
Answer: A
Explanation:
An informal usability review can be conducted by anyone, including stakeholders or developers, and does not require formal usability training or qualifications. It is typically subjective and based on general impressions.
In contrast, an expert usability review (also called heuristic evaluation) is conducted by a trained usability expert who applies recognized usability principles. This is what differentiates the two approaches most clearly. Options A and C are misleading; expert reviews can be informal in format, and informal reviews aren't necessarily based solely on opinion. Option D is incorrect since both informal and expert reviews can be conducted individually or in groups.

NEW QUESTION # 22
Which of the following statements best describe Rapid Iterative Testing and Evaluation?
- A. Testing focuses on instant redesigns and confirming made changes
- B. Testing happens on a regular basis, e.g. each Monday
- C. Testing is informal and many potential users can be accessed
- D. Testing is quantitative
Answer: A
Explanation:
Rapid Iterative Testing and Evaluation (RITE) is a usability method in which usability issues are identified and addressed in short cycles. Unlike traditional usability testing, RITE allows for immediate redesigns and retesting of the improved version within the same study. The goal is to refine the design quickly based on observed usability issues. Option A confuses scheduling with methodology, B is too vague, and D inaccurately characterizes RITE as quantitative, while it is typically qualitative. Therefore, C accurately reflects the purpose and approach of RITE.

NEW QUESTION # 23
In a short conversation, a potential customer mentions that accessibility is of great importance to them. What does this mean?
- A. They also seek to address users with limitations
- B. They use prototyping in their development process
- C. They focus on agile development
- D. They focus on quantitative usability evaluations
Answer: A
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 # 24
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?
- A. Which mobile operating system do you prefer?
- B. Put the first phone you find in your shopping cart!
- C. Enter the item number "1469483" in the search box and click "OK". Put the first item in the cart by clicking "add to bag". Then, click on "checkout" in order to start the order process. After that, fill in the form and click on "submit".
- D. Your phone broke and you're looking for a new smartphone. Your budget is 200$ and it should have an infrared sensor as you like to operate your home entertainment system with it. Find a suited smartphone and order it!
Answer: D
Explanation:
Option B represents a realistic, goal-oriented scenario that reflects how an actual user would interact with the website. It incorporates context, user intent, constraints, and desired outcome-all characteristics of well- designed usability tasks. Option A is vague and lacks real-world motivation. Option C is too prescriptive and limits insight into user behavior, while D is a survey question, not a usability task. According to Nielsen Norman Group and ISO 25062, the best usability tasks are scenario-based, realistic, and outcome-driven- making B the correct answer.

NEW QUESTION # 25
What is the System Usability Scale (SUS)?
- A. A simple, ten-item attitude scale giving a global view of subjective assessments of usability.
- B. Testing to evaluate the degree to which the system can be used by specified users with effectiveness, efficiency and satisfaction in a specified context of use.
- C. 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.
- D. A requirement on the usability of a component of system
Answer: A
Explanation:
The System Usability Scale (SUS) is a standardized, reliable tool used to measure perceived usability. It consists of 10 items with five response options (from strongly agree to strongly disagree). It is widely used due to its simplicity and effectiveness in providing a single score to reflect a user's overall satisfaction with a system. Option A refers to ISO's definition of usability testing, B describes a task in usability testing, and D refers to a usability requirement, not SUS. Therefore, the correct description of SUS is option C.

NEW QUESTION # 26
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 that the usability test plan has been properly reviewed
- B. Check consumed resources regularly and compare with the estimates
- C. Check that findings are communicated to the stakeholders
- D. Check whether the usability test report conforms to the best practices
Answer: B
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 # 27
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. Usability review
- B. Unmoderated usability test
- C. Usability maturity assessment
- D. Usability test in the lab
Answer: A
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 # 28
Your last 20-pages usability test report wasn't received well by the developers; only two of the 25 usability problems have been fixed. This time, you want to stick to the best practices in order to obtain better acceptance by the development team.
What are you going to do differently this time?
- A. Add the low-priority findings you didn't include in the first report
- B. Make the report more detailed and longer
- C. Include positive findings in the report, not only usability problems
- D. Include contact details of the test participants so that the development team can contact them in case they have questions
Answer: C
Explanation:
Usability test reports are more effective when they are balanced and include not only problems but also what worked well. Including positive findings increases credibility, encourages the development team, and helps them understand what should remain unchanged. Option B violates privacy and ethical standards. Option C may dilute focus, and D could worsen the problem by making the report less accessible. Thus, the best practice supported by usability.gov and Nielsen Norman Group is to include both positive and negative findings.

NEW QUESTION # 29
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 are true, iii is false
- B. i is true, ii & iii are false
- C. ii & iii are true, i is false
- D. i, ii and iii are true
Answer: D
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 # 30
During a usability test, a user suggested that a quick search box on every page would help a lot for several of the main tasks. You added this finding to the list.
What's the correct classification for these kinds of findings?
- A. Positive finding
- B. Usability problem
- C. Good idea
- D. Functional problem
Answer: C
Explanation:
In usability evaluations, a distinction is made between actual usability problems (where a user struggles to complete a task or is confused by the interface) and suggestions or ideas that users provide based on their preferences or perceived improvements. When a participant offers a new feature idea (such as a quick search box), this is classified as a "good idea" or "feature suggestion," not necessarily a usability problem. It may inform future design enhancements but does not indicate a failure in usability for existing functionality.

NEW QUESTION # 31
How can the approach for conducting user surveys be summarized best?
- A. Write survey plan, interview users and stakeholders, select questionnaire, deploy questionnaire, analyze, communicate
- B. Write survey plan, write schedule, select questionnaire, recruit users, remind users, communicate
- C. Write survey plan, write schedule, select questionnaire, recruit users, analyze, communicate
- D. Write survey plan, interview users and stakeholders, select questionnaire, recruit users, remind users, communicate
Answer: A
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 # 32
Which of the following is the highest WCAG conformance level, promising the most accessible content?
- A. Single A (A)
- B. Quadruple A (AAAA)
- C. Triple A (AAA)
- D. Double A (AA)
Answer: C
Explanation:
The Web Content Accessibility Guidelines (WCAG) define three levels of conformance for web content accessibility:
Level A (Single A) is the minimum level of compliance.
Level AA (Double A) is the standard recommended for most websites, balancing accessibility and design.
Level AAA (Triple A) is the highest and most comprehensive level of accessibility, covering the widest range of needs.
There is no such level as "Quadruple A (AAAA)," making option D invalid.
Thus, WCAG Triple A (AAA) promises the most accessible content, even though it may not always be practically achievable for all types of content.

NEW QUESTION # 33
Which of the following statements about usability testing is true?
- A. The preparation of a usability test is optional
- B. A usability test consists of one usability test session
- C. Before the usability test sessions, a pilot usability test session can be conducted
- D. The conditions under which a usability test is done are irrelevant
Answer: C
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.
