Product Thinking: Heuristics, Accessibility, Redesign, and Validation
Prompt
Pick one digital product you use daily (web or mobile). Identify:
- One specific interface you love.
- One specific function you dislike.
Using usability heuristics (e.g., Nielsen) and accessibility standards (e.g., WCAG 2.1/2.2), do the following:
- Analyze why the loved interface succeeds (reference specific heuristics and WCAG criteria).
- Analyze why the disliked function fails (reference specific heuristics and WCAG criteria).
- Propose a concrete redesign for the disliked function, including accessibility considerations.
- Define success metrics and guardrails.
- Outline an experiment or telemetry plan to validate the change and mitigate novelty effects.
Assume you can instrument events and run user-level A/B tests. Keep your answer structured and concise.
