Explanation: ISO 9241-210 defines Human-Centred Design (HCD) as an approach to systems design and development that aims to make interactive systems more usable by focusing on system use, applying human factors/ergonomics, and integrating usability knowledge throughout the lifecycle. It ensures systems meet user needs and context rather than forcing users to adapt to technology. Other options mischaracterize HCD as purely visual, technical coding, or end-of-life testing.

Explanation: ISO 9241-11 explicitly defines usability as 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. Effectiveness measures task completion accuracy, efficiency measures resources expended, and satisfaction measures user comfort and positive attitudes.

Explanation: According to ISO 9241-210, User Experience is broader than usability; it encompasses all the user's emotions, beliefs, preferences, perceptions, physical and psychological responses, behaviors, and accomplishments before, during, and after use. Usability is a subset focusing on how effectively, efficiently, and satisfactorily a user can complete tasks in a specified context.

Explanation: ISO 9241-210 outlines four core iterative design activities: (1) Understand and specify the context of use, (2) Specify the user requirements, (3) Produce design solutions to meet user requirements, and (4) Evaluate the designs against requirements. This evaluation step feeds iteratively back into earlier steps until requirements are satisfied.

Explanation: Understanding and specifying the context of use involves identifying who will use the system (users), what they are trying to achieve (goals and tasks), and the environmental conditions (hardware/software environment, physical lighting/noise, organizational culture) under which the system operates. This provides the baseline for defining valid user requirements.

Explanation: Active user involvement throughout the design cycle provides an invaluable source of context, feedback, and empirical evaluation data. Direct involvement prevents design teams from relying on assumption-based design, ensuring the resulting system effectively supports actual working practices and user needs.

Explanation: ISO 9241-210 highlights that human-centred design benefits from multidisciplinary skills and perspectives. Combining expertise in user research, ergonomics, visual design, software architecture, technical writing, and domain business knowledge ensures balanced design choices that address user, technical, and business constraints.

Explanation: In ISO 9241-210, iteration is triggered whenever evaluating design solutions against user requirements uncovers usability problems, unfulfilled goals, or new context-of-use findings. This user evaluation feedback loop forces refinements to both the design solutions and the specified user requirements until evaluation criteria are satisfied.

Explanation: Context of use in ISO 9241-11 comprises users, tasks, equipment (hardware, software, materials), and the physical and social environment in which the product is used. Internal source code repository architecture is an implementation detail of software development, not part of the external user context of use.

Explanation: In HCD, user requirements state what the user needs to achieve within their context of use (e.g. 'The field nurse must be able to record patient vitals using one hand within 30 seconds'). Functional specifications define how the software system will technically implement features (e.g. API endpoints, database schemas) to fulfill those requirements.
