Unlockable Challenges
Engaging couriers with a succession of rewards
My Role
Led the product design implementation, including Competitive Analysis, Prototyping, UI/UX Design, and Usability Testing.
Timeline
Jan - Mar 2025
Project Type
Feature in the courier mobile app, designed on iOS. Used the PIE design system
Outcomes
Our goal is to improve courier engagement during delivery: shifts worked, shifts completed, and orders accepted. This project has been put on hold due to shifting business priorities.
Final Design
PROJECT Summary
Couriers, or delivery drivers, are given “Challenges” to complete for a reward. For example, a Challenge could be “Complete 6 deliveries for a $25 reward”.
This project revolves around “Unlockable Challenges”. These are Challenges with sections where completing each section results in an immediate reward and unlocks the next section.
Existing research has found the structure of Unlockable Challenges is highly motivating. It provides couriers with an early win and a sense of progression as they accomplish each checkpoint. This creates feelings of achievability, which drives satisfaction and boosts acceptance rate, shifts worked, and PtoD (delivery speed).
I was tasked with updating the current UI to accommodate Unockable Challenges.
I used the following How Might We’s to guide my ideation and design.
How might we alter the existing Challenge Hub to accommodate Unlockable Challenges?
How might we design a clear, intuitive, and engaging Unlockable Challenges experience?
How might we show the courier’s progress in a motivating but non-intrusive way to increase offer acceptance, shifts competed, and shifts worked?
How might we increase a courier’s sense of accomplishment and competency as they progress through Unlockable Challenges?
My approach included discovery, design, unmoderated user testing, tech assessments, and a handoff.
