ISQI ISTQB Certified Tester-Foundation Level - Usability Testing Sample Questions (Q29-Q34):NEW QUESTION # 29
Which of the following is the correct distinction between formative and summative usability evaluation?
A. Summative evaluations assess the outcome, formative evaluations focus on improvement
B. Summative evaluations mostly rely on user tests, formative evaluations require experts
C. Summative evaluations focus on improvement, formative evaluations assess the outcome
D. Summative evaluations mostly rely on experts, formative evaluations require users
Answer: A
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 # 30
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. Interview users, iteratively develop prototypes, and evaluate the software
C. Iteratively develop prototypes, perform expert reviews, and integrate found issues
D. Define requirements, develop the software, and perform acceptance test
Answer: B
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 # 31
What is the System Usability Scale (SUS)?
A. A requirement on the usability of a component of system
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 simple, ten-item attitude scale giving a global view of subjective assessments of usability.
Answer: D
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 # 32
Which of the following statements about usability testing is true?
A. A usability test consists of one usability test session
B. Before the usability test sessions, a pilot usability test session can be conducted
C. The conditions under which a usability test is done are irrelevant
D. The preparation of a usability test is optional
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 # 33
Which of the following is a principal task of the usability test moderator role?
A. Define testing tasks
B. Write a usability test plan
C. Create a survey plan
D. Log usability problems
Answer: A
Explanation:
The usability test moderator plays a crucial role during the execution phase of a usability test. Their principal task is to facilitate the test sessions by guiding participants through predefined testing tasks, observing behaviors, and ensuring that the test environment is neutral and free from bias. Defining testing tasks, however, is primarily done during the test design phase by the usability test designer or analyst, but the moderator ensures these tasks are clearly communicated and administered to participants during the session.
Logging usability problems (option B) is often done by observers or analysts reviewing session recordings or notes, not directly by the moderator during live testing. Creating a survey plan (option C) and writing the usability test plan (option D) are preparatory activities generally done before the test sessions and are not the moderator's main focus. Therefore, the principal role of the moderator centers on conducting the sessions and managing task delivery effectively to obtain authentic user interaction with the system under test.
