Most Expensive Design Mistakes (Ever) and how to avoid them
summary
Large-scale examples and hard numbers: Uber runs A/B tests by city and reads heatmaps and eye‑tracking to find why users ignore buttons; over 16% of visitors give up in seconds and new users who finish a key task are 10%+ more likely to convert. Concrete failures include a wireless juice machine that breaks when the app fails, inconsistent labels like multiple “confirm pickup” copies, and deceptive UI that forced costly refunds. Practical fixes: unify components, run targeted experiments, provide fallbacks.
