Your team has finished analyzing customer-satisfaction metrics for fiscal Q2. According to a mandate from corporate communications, the results summary must be a static document (such as a PDF, DOC, or image) for posting on the public investor-relations site. The content must also comply with Section 508 and WCAG-AA standards to ensure board members who rely on screen-reader software can independently review it. Finally, stakeholders will download the report on both mobile and desktop devices. Given these requirements, which communication approach provides the most accessible experience?
Export the visual summary to a tagged PDF that includes alt text for every chart, a logical reading order, and a high-contrast color theme.
Publish an interactive HTML5 dashboard in which insights appear only when users hover over elements or interpret color cues.
Email the underlying Excel workbook that uses red/green conditional formatting to indicate trends but contains no supporting narrative.
Record a narrated screencast walk-through of the dashboard and embed the video on the site without closed captions or transcripts.
Exporting the visuals to a properly tagged PDF that uses high-contrast colors and includes concise alt text meets all stated constraints. A tagged PDF carries a logical reading order and metadata that screen readers can parse, while alt text conveys the meaning of charts for users who cannot see them. High-contrast colors improve legibility for low-vision readers and satisfy WCAG contrast thresholds.
The interactive HTML5 dashboard is disallowed because the site only accepts static files, and hover-only interactions are not keyboard or screen-reader friendly. The color-coded Excel workbook fails WCAG 1.4.1 because color is the sole cue and offers no alt text or meaningful structure. The narrated screencast, lacking captions or a text alternative, excludes deaf or hard-of-hearing users and cannot be parsed by screen readers, so it does not satisfy the accessibility requirement.
