Relevant Standards
This domain tests whether you know which standard says what. Items typically give a task, such as reporting a benchmark test, designing a human-centred process or choosing a quality model, and ask for the matching standard.
Core standards
- ISO 9241-11: defines usability (effectiveness, efficiency, satisfaction in a context of use) and explains how to measure it. It defines; it does not set pass thresholds.
- ISO 9241-210: human-centred design for interactive systems. The process is to understand context, specify requirements, produce design solutions, evaluate against requirements, and iterate.
- ISO 9241-110: interaction principles such as suitability for the task, self-descriptiveness, conformity with expectations, learnability, controllability and error tolerance.
- ISO/IEC 25010: product quality and quality-in-use model; quality in use covers effectiveness, efficiency, satisfaction, freedom from risk and context coverage.
- ISO/IEC 25062: Common Industry Format (CIF) for usability test reports, the template for summative reporting.
- ISO/IEC/IEEE 29119: software testing processes and documentation, the frame around test planning.
- WCAG 2.0/2.1/2.2 from W3C, with WCAG 2.0 also published as ISO/IEC 40500, referenced by EN 301 549 in the EU and Section 508 in the US.
Worked example
A public-sector buyer asks a vendor for comparable evidence that a product meets usability targets. Use a summative test and report it in ISO/IEC 25062 CIF format, using ISO 9241-11 metrics (completion, time, satisfaction) with defined user groups and context. Reasoning: CIF exists so reports can be compared; 9241-11 supplies the measures, not the pass mark.
Traps
Claiming 9241-11 prescribes participant numbers or thresholds; mixing the 9241-210 process with the 9241-11 definition; calling WCAG an ISO standard without the 40500 qualifier.
