Warehouse Automation System

Proposed and helped implement a database consolidation that doubled operational efficiency — one computer now handles the workload of two forklift operators, with fewer errors and faster onboarding.

Project Overview

Identified an inefficiency on the warehouse floor and worked with a third-party WMS vendor to consolidate three fragmented inventory tables into a single intuitive view, reducing cognitive load and bridging the skill gap between experienced and new staff.

My Contributions

  • Identified the inefficiency and pitched the consolidation to management and the WMS vendor
  • Tested the new tables, reported bugs, and documented edge cases
  • Collaborated with WMS developers on schema and SQL changes
  • Trained staff on the new workflow with practical tips and best practices
The Problem

The warehouse relied on three separate tables that staff had to cross-reference simultaneously:

  1. Inventory pallet contents (what items are where)
  2. Collection status (items picked and ready)
  3. Customer order tracking (item locations for the day)

This forced staff to mentally consolidate data across three views, increasing cognitive load and error risk during high-volume operations.

Solution

Working with the WMS development team, we designed a single unified table consolidating all three functions. Initial testing revealed the table was static (only updated by warehouse input). I traced this to order date misalignment between systems; we then implemented dynamic synchronisation to keep it live.

  • Mapped variables and dependencies to understand the full data landscape
  • Identified essential vs. redundant fields to reduce cognitive load
  • Coordinated tight deadlines via documentation, calls, and detailed PDFs
Results & Impact

Primary impact: One computer can now handle the workload of two forklift operators — effectively doubling operational efficiency.

  • Consolidated system — three tables merged into a single unified view
  • Fewer errors — eliminated team collisions and missed customer items
  • Faster onboarding — narrower skill gap between experienced and new staff
  • Better accuracy — real-time data sync increased inventory confidence
  • Scalability — workflow scales seamlessly across team sizes
