A usability researcher is planning a study for a medical device used by nurses in a busy hospital ward. The researcher wants to measure usability according to ISO 9241-11. Which set of variables MUST be explicitly defined to properly apply the ISO 9241-11 definition?

Users, goals, and context of use (equipment, environment, and social setting)

Code quality, API design, and database performance

Development cost, timeline, and team size

Visual design, brand identity, and marketing strategy

A usability team is developing a new medical device interface. They have limited budget and time. The team wants to comply with ISO 9241-210 while also meeting regulatory requirements for usability testing. Which approach BEST balances the need for human-centred design with the constraints?

Conduct a single large usability test at the end with many users to satisfy regulatory requirements

Skip formative testing and conduct only a summative test at the end to save time

Use expert heuristic evaluation only, as it is faster and cheaper than user testing

Conduct iterative formative evaluations with a small number of users early in design, followed by a summative test with a larger sample for regulatory evidence

A design team is working on a new e-commerce website. They have a tight deadline and limited resources. The team lead wants to follow ISO 9241-210 but is concerned about the cost of user involvement. Which approach BEST aligns with ISO 9241-210 while managing the constraints?

Use only expert reviews to save time and money

Conduct one comprehensive usability test with many users at the end of development

Defer all usability testing until after the product launch

Conduct short, iterative usability tests with a few users at each design stage, using low-fidelity prototypes

Which activity is a key part of the human-centred design process described in ISO 9241-210?

Documenting user requirements only after the product is complete

Iterating design solutions until user requirements are met

Conducting a single usability test at the end of development

Focusing on technical feasibility before considering user needs

A design team is developing a new patient portal for a hospital. They have completed user research and identified that patients need to view lab results, schedule appointments, and message their doctors. According to ISO 9241-210, what should the team do to ensure the design is human-centred?

Rely on the hospital's IT department to make all design decisions

Create design prototypes and evaluate them with patients in iterative cycles

Use a standard template for all patient portals without user testing

Develop the full system first and then ask patients to test it

Part of the Usability and Accessibility Standards domain, which makes up ~15% of our current practice bank. ISTQB does not publish an official question count, but from its 60-minute exam (~25–40 total, ~4–6 in this domain), expect 1–1 from this objective — we provide 25 practice questions to prepare you well beyond it.
