The Problem

Why this needed to exist.

Garment factories were stitching together spreadsheets, legacy desktop tools, and pen-and-paper for production, costing, and HR. Reporting across factories took days and reconciliation errors were routine.

The Approach

How I solved it.

Built a modular ERP with role-based modules — Production, Merchandising, Inventory, QC, HR/Payroll — sharing a single source of truth. Multi-factory dashboards and an audit-friendly data model replaced the spreadsheet sprawl.

Personas

Who I designed for.

Each persona shaped a specific surface of the product. Goals and pain points were validated through interviews and shadowing.

    Domain Discovery

    Two weeks on-site at partner factories observing actual workflows on the production floor.

  4. 04

    Iterative Rollout

    Shipped one module per quarter, training and incorporating feedback before the next.
