Through extensive user research involving interviews with 20 staff members and real-time observations of the reversal process, I identified key pain points such as difficulties in tracking duplicates and a lack of accountability. The design solution incorporated features like duplicate detection algorithms, a transaction lock mechanism, and a centralized dashboard for monitoring reversal actions. The impact was substantial: a 95% reduction in duplicate reversals was achieved within three months post-launch, leading to improved operational efficiency and boosted stakeholder confidence. Key learnings emphasized the importance of user-centered design and iterative feedback loops for continuous improvement.
