Olive Young Implements Cycle Counting Feature for LA Stores in 3 Days Using AI and Parallel Development

An Olive Young global store backend developer reflected the cycle counting requirements from local staff during a business trip to Los Angeles, USA, developing and applying the feature on-site within 3 days. The previous 6-step sequential process resulted in long communication wait times due to time zone differences, taking several weeks to reflect changes on-site; this was resolved by having BPO, PM, developers, and QA work in parallel while gathered in one place.

Development Strategy and AI Utilization

The development scope was limited to functions unavailable to store staff, reducing it to a PoC (Proof of Concept) approach. During the development phase, AI generated drafts for the PDA frontend, backend API, and integration parts, while developers focused solely on core decision-making logic such as quantity calculation and discrepancy handling. QA also improved efficiency by using AI tools to generate test cases and review coverage gaps.

On-Site Implementation Results

During the PoC period (August 13–September 1), 32 out of 37 counting missions were completed across two LA stores (86.5% completion rate), and physical inventory for a total of 401 products was counted. Of the 37 inventory adjustments that occurred during the same period, 92% were processed through this feature. Notably, the Pasadena store demonstrated on-site adaptability by actually using the feature every day for 5 consecutive days after requesting it be standardized twice a week.

Limitations and Future Challenges

Currently, the system maintains a simplified structure by replacing role-based access control with 'person-in-charge input' and manually specifying the automatic calculation of counting targets (A/B/C grades). In the future, aligned with Olive Young's expansion of overseas stores, plans include establishing a role-based permission system, developing automatic counting target calculation logic, and implementing a dedicated exception handling flow.
