NEW QUESTION # 15
In a short conversation, a potential customer mentions that accessibility is of great importance to them. What does this mean?
- A. They focus on agile development
- B. They focus on quantitative usability evaluations
- C. They also seek to address users with limitations
- D. They use prototyping in their development process
Answer: C
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 # 16
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 answers to the test questions.
- C. It contains pre-session interview questions.
- D. It contains post-session interview questions.
Answer: B
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 # 17
What is the System Usability Scale (SUS)?
- A. A simple, ten-item attitude scale giving a global view of subjective assessments of usability.
- B. A requirement on the usability of a component of system
- C. 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.
- D. 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.
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 # 18
A "usability test participant" ...
- A. ... helps to set up the system used for the usability test.
- B. ... is a representative user who solves typical tasks in a usability test.
- C. ... can be the organizer of a usability test.
- D. ... is a person who observes a usability test.
Answer: B
Explanation:
A usability test participant is a person selected to represent the target user group and asked to perform specific tasks in a usability test. Their actions, reactions, and feedback help identify usability issues and evaluate the system's effectiveness, efficiency, and user satisfaction. This role is strictly observational and does not involve organizing, observing, or setting up the test. Options A, B, and C describe other roles (e.g., technical support, observers, or moderators). Only option D accurately reflects the definition of a usability test participant.

NEW QUESTION # 19
Which of the following is the best description for a usability test session?
- A. A period of time in which a usability test participant is executing tests, moderated by a moderator and observed by a number of observers.
- B. A test activity specified by the moderator that needs to be accomplished by a usability test participant within a given period of time.
- C. A document specifying a sequence of actions for the execution of a usability test.
- D. A black-box test technique in which test cases are designed to execute usability scenarios.
Answer: A
Explanation:
A usability test session is a controlled period during which a test participant performs tasks using the system under test while being observed by a moderator and sometimes additional stakeholders or observers. The goal is to understand how users interact with the interface and identify usability problems. Option A describes an individual task, not the whole session. Option C refers to a test plan or test script, and Option D describes a test technique rather than a usability session. Thus, option B provides the most accurate and comprehensive definition.

NEW QUESTION # 21
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, interview users and stakeholders, select questionnaire, recruit users, remind users, communicate
- C. Write survey plan, write schedule, select questionnaire, recruit users, analyze, communicate
- D. Write survey plan, write schedule, 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 # 22
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. The usability of the website is bad - five minutes is way too long
- B. The usability of the website is good - five minutes is a fair amount of time
- C. That depends on the context of use as users may have different expectations
- D. That depends on the accessibility of the website
Answer: C
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 # 23
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. ii, iv & v are true, i & iii are false
- C. i, ii & v are true, iii & iv are false
- D. iii, iv & v are true, i & ii are false
Answer: B
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 # 24
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 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
- C. 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)
- D. 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
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 # 25
A large customer complained that a business application developed by your company sometimes transfers the wrong amount of money to clients, although there are no complaints of the actual users. The expected amount differs from the actually transferred amount by a factor of 10 or 100. After analyzing the log files, you found out that the application itself works fine. The problem seems to be caused by confusing text fields and labels for the decimal place, leading to user errors.
Which usability risk should be reasonably addressed for the next release?
- A. Users won't buy or use the software product because it lacks effectiveness, efficiency or satisfaction
- B. Users resist using a software product which is essential for their daily work because it lacks usability
- C. Increased liability through risk to financial loss caused by a poorly designed or deceptive user interface
- D. Users buy the software product but repeatedly need to call support because they don't understand how to use it
Answer: C
Explanation:
The scenario describes a situation where the interface misleads users into making serious financial mistakes due to poor design, such as confusing decimal separators. Even though the system functions correctly, it facilitates critical user errors. This constitutes a major usability risk with potential legal and financial consequences. Therefore, the correct risk to address is increased liability due to financial loss caused by a poorly designed or deceptive interface (option D). The other options focus on usability-related dissatisfaction, resistance, or lack of adoption, which are not the key concern in this scenario.

NEW QUESTION # 26
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. Opinion of the management
- B. Statutory Code of Practice
- C. Usability standards
- D. Functional requirements
Answer: C
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 # 27
What location is NOT suitable for conducting a usability test?
- A. A room where no action of the user can be seen or recorded by any means.
- B. A room at the place where the test participant lives or works.
- C. Two office rooms that are connected by a video link.
- D. A public place, such as a cafe.
Answer: A
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 # 28
Which of the following statements about usability testing is true?
- A. The conditions under which a usability test is done are irrelevant
- B. Before the usability test sessions, a pilot usability test session can be conducted
- C. The preparation of a usability test is optional
- D. A usability test consists of one usability test session
Answer: B
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 # 29
What does the Equality Act address?
- A. It states that websites have to adhere to the WCAG conformity level AA
- B. It obligates organizations to make sites accessible at all costs
- C. It states that websites have to adhere to the WCAG conformity level A
- D. It protects people from discrimination in the workplace and in wider society
Answer: D
Explanation:
The Equality Act 2010 (UK) is legislation designed to protect individuals from discrimination in various areas, including employment and access to goods and services-this includes digital products like websites.
While it does not directly mandate WCAG compliance levels (A or AA), it implies that digital services must be accessible to users with disabilities. Organizations are required to make "reasonable adjustments" to avoid discrimination. Therefore, the most accurate and comprehensive answer is B.

NEW QUESTION # 30
Which of the following is the correct distinction between formative and summative usability evaluation?
- A. Summative evaluations mostly rely on user tests, formative evaluations require experts
- B. Summative evaluations assess the outcome, formative evaluations focus on improvement
- C. Summative evaluations mostly rely on experts, formative evaluations require users
- D. Summative evaluations focus on improvement, formative evaluations assess the outcome
Answer: B
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.
