Framework: Stakeholder Needs -> User Journey Placement -> UI Mechanics -> Incentives & Transparency.
1. Stakeholder Needs:
- Couriers: Fair compensation, immediate visibility of earned tips, motivation for high-quality service.
- Diners: Frictionless giving, transparency that 100% goes to the courier, zero guilt pressure.
- Platform: Increased courier retention and customer goodwill.
2. Placement in User Journey:
- Pre-order vs Post-delivery: Offer a pre-order tip option with smart percentage buttons ($2, $3, $5, Custom), but allow diners to modify or add tips up to two hours post-delivery based on service quality.
3. UX Mechanics:
- Clear transparency banner: '100% of your tip goes directly to your courier'.
- Contextual nudges during severe weather (e.g., 'It is raining heavily in your area—consider thanking your courier').
4. Success Metrics:
- Courier earnings per hour, courier retention rate, tip adoption rate (% of orders with tips), customer checkout abandonment rate (guardrail metric).
