QUESTION 1 According to ISO 9241-210, what is the fundamental
definition of human-centred design (HCD)?
• A. An approach to systems design and development that aims to
make interactive systems more usable by focusing on the use of
the system and applying human factors/ergonomics and usability
knowledge
• B. A graphic design process focused exclusively on making digital
interfaces aesthetically pleasing and modern
• C. A software engineering methodology that prioritizes database
architecture over user workflows
• D. A marketing strategy designed to increase immediate digital
sales conversions
Correct Answer: A. An approach to systems design and development
that aims to make interactive systems more usable by focusing on the
use of the system and applying human factors/ergonomics and usability
knowledge
Detailed Rationale: ISO 9241-210 defines human-centred design as an
iterative framework emphasizing human factors, ergonomics, and
usability throughout the system lifecycle.
QUESTION 2 How does ISO 9241-11 formally define usability?
, • A. The extent to which a system, product or service can be used by
specified users to achieve specified goals with effectiveness,
efficiency and satisfaction in a specified context of use
• B. The speed at which a computer processor executes application
code without crashing
• C. The total number of graphical icons displayed on a single
webpage interface
• D. The degree to which software code adheres to international
programming syntax standards
Correct Answer: A. The extent to which a system, product or service can
be used by specified users to achieve specified goals with effectiveness,
efficiency and satisfaction in a specified context of use
Detailed Rationale: ISO 9241-11 establishes the three core pillars of
usability: effectiveness (accuracy/completeness), efficiency (resources
expended), and satisfaction (comfort/acceptability).
QUESTION 3 What is the primary distinction between formative and
summative usability evaluations?
• A. Formative evaluations are conducted during the design and
development phase to diagnose and fix usability flaws, whereas
summative evaluations assess the overall usability and
effectiveness of a completed product
• B. Formative evaluations are performed exclusively by software
developers, while summative evaluations are done by legal
auditors
, • C. Formative evaluations measure financial return on investment,
while summative evaluations measure server load times
• D. Formative evaluations use quantitative surveys only, while
summative evaluations use paper sketches
Correct Answer: A. Formative evaluations are conducted during the
design and development phase to diagnose and fix usability flaws,
whereas summative evaluations assess the overall usability and
effectiveness of a completed product
Detailed Rationale: Formative testing is diagnostic and iterative
("forming" the product), while summative testing is evaluative and
benchmarking ("summing up" the finished design quality).
QUESTION 4 What key elements comprise a comprehensive "Context of
Use" analysis according to human-centred design standards?
• A. The users, the tasks they perform, the equipment
(hardware/software) they use, and the physical and social
environments in which they operate
• B. The company's annual revenue targets and marketing budget
• C. The programming languages used to host the database servers
• D. The legal copyright holders and trademark registrations of the
brand
Correct Answer: A. The users, the tasks they perform, the equipment
(hardware/software) they use, and the physical and social environments
in which they operate
, Detailed Rationale: Understanding the full context of use ensures that
design solutions align with the actual realities, constraints, and
environments of end users.
QUESTION 5 What is the primary purpose of conducting generative
(exploratory) user research early in a project lifecycle?
• A. To discover unmet user needs, understand user behaviours,
mental models, and pain points before committing to a specific
design solution
• B. To prove to stakeholders that the pre-selected software
architecture is infallible
• C. To test the colour contrast of finished high-fidelity wireframes
• D. To calculate final advertising budgets and media placement
schedules
Correct Answer: A. To discover unmet user needs, understand user
behaviours, mental models, and pain points before committing to a
specific design solution
Detailed Rationale: Generative research builds foundational empathy
and insight, ensuring that the team solves the right problem rather than
building the wrong solution efficiently.
QUESTION 6 What is the primary methodological advantage of
contextual inquiry over traditional laboratory interviews?
• A. Researchers observe users in their natural, everyday work or
home environment, capturing unexpressed habits, environmental
interruptions, and tacit knowledge
