The human-centered design process emphasizes iterative development—testing and refining designs through multiple cycles. In the scenario, the project manager interviewed users and evaluated a prototype but did not iterate based on feedback. Skipping iteration likely resulted in unmet user needs. Human-centered design, per ISO 9241-210, includes: understanding context of use, specifying requirements, producing design solutions, and evaluating—repeated iteratively. Hence, option D (“iterate”) is correct.

The Web Content Accessibility Guidelines (WCAG) define three levels of conformance for web content accessibility:

Level A (Single A) is the minimum level of compliance.

Level AA (Double A) is the standard recommended for most websites, balancing accessibility and design.

Level AAA (Triple A) is the highest and most comprehensive level of accessibility, covering the widest range of needs.

There is no such level as “Quadruple A (AAAA),” making option D invalid.

Thus, WCAG Triple A (AAA) promises the most accessible content, even though it may not always be practically achievable for all types of content.

At an early development stage where only a rudimentary prototype exists, a usability review (e.g., expert or heuristic review) is the most effective method. It allows usability specialists to identify potential usability issues without the need for a fully functioning product. Reviews can provide immediate, actionable feedback to guide design improvements before moving into more resource-intensive usability testing. An unmoderated usability test (B) or lab test (D) may be impractical at this stage due to limited interactivity. A usability maturity assessment (C) evaluates organizational processes and is not applicable to evaluating a specific prototype.
