SAFETY PERCEPTION UPGRADE
Macro Background
In the Latin America region, DiDi International introduced a new PIN code feature.
Purpose
By passively enabling the PIN code at the platform level, guide passengers to actively enable the PIN code for each subsequent trip. This is intended to increase the PIN code activation rate and improve users’ perception of safety during the trip.
Current Situation
Research shows that the PIN code boarding feature can effectively improve the safety perception between drivers and passengers. However, the current triggering of the PIN code mainly relies on drivers or passengers enabling it proactively, and the range of strong triggering scenarios is relatively small, resulting in weak user awareness. Therefore, for certain specific scenarios and user groups, a mandatory PIN code activation strategy is expected to increase the PIN code activation rate.
User Pain Points
Users may have already actively turned off the PIN code, but the platform still forces the PIN code to be enabled to ensure safety, which affects user privacy. When users request a ride in risky scenarios, they may feel a lack of safety. Some users want to use the PIN code to ensure safety, but they cannot find where to enable it.
Design Goals
Platform level: Improve passengers’ sense of safety.
User level: Allow passengers to enable the PIN code through a faster path.
Product level: Increase the PIN code activation rate.


3.Final Option

Post-Launch Key Performance Indicators
Regional Rollout: Successfully deployed across MX, CO, AR, and CL. Conversion: Precision targeting in high-risk scenarios drove the PIN adoption rate from 11% to 45%. User Sentiment: Post-launch surveys confirmed a significant uplift in safety perception among both drivers and passengers. Operational Stability: Despite the shift to a mandatory strategy, Customer Support volume (TPO) remained stable with no significant increase, validating a seamless user experience.
what i learn
When Design and Product disagree, utilize A/B testing (data-driven) and edge-case simulations (logic alignment) to bridge the gap, ensuring a balanced synergy between business goals and user experience.
To identify the optimal solution, I evaluate functionality, UX, and scalability. When visions clash, I advocate for rapid feasibility testing (within one week) to validate ideas with data, minimizing the project cycle while maximizing efficiency.
