Adding FEFO to Ginee WMS

Overview

Another key project I contributed to was adding a First Expired, First Out (FEFO) feature to a Warehouse Management System (WMS). The idea originated from user requests. At the time, the WMS only supported a FIFO (First In, First Out) outbound method, which caused challenges for sellers dealing with products that have expiration dates, such as food and medicine.

To address this, I began with user research, interviewing warehouse teams to understand their day-to-day operations and pain points, and studying competitors’ approaches. After several rounds of research, discussion, and development, our team successfully launched the FEFO feature.While it did not result in a significant user growth (around 3–5%, since not all users utilized WMS), it greatly increased satisfaction among existing users who required FEFO.

My Contributions

I supported the product manager by conducting research and providing input for the PRD (Product Requirements Document). Key aspects I worked on included:

  • Designing adjustments for inventory logic, allowing each product/location to choose FIFO or FEFO
  • Planning multi-level alert notifications before product expiry
  • Mapping inbound flow for FEFO products (desktop & PDA)
  • Updating inventory display to include batch and expiry date information
  • Outbound flow enhancements (picking list updates, PDA integration)
  • Return flow handling for FEFO items
  • Expiration management workflows (e.g., outbound list for products expiring within a quarter)
  • Drafting an NED (Near Expiry Date) report plan

My research and documentation became a valuable reference for the product team in finalizing the PRD and guiding development.

Result

Through these insights, we mapped how FEFO should seamlessly integrate into the existing WMS workflow. This project gave me hands-on experience in translating user needs into system capabilities and ensuring the feature truly supported warehouse operations.
