Inventory Tracking App

Inventory Tracking App — Carsome case study

The Context

Carsome's logistics team tracked vehicle movement via Google Sheets, WhatsApp, and email. A digital tool existed. Staff had abandoned it. The workflows didn't match ground reality, so workarounds felt easier than the product.

The Challenge

Field visits and staff interviews found the real problems: confusing navigation, heavy reliance on handovers that assumed physical presence when reality is everyone chasing the next location, pickup and drop-off points with no internet access, and an interface built around system logic instead of the tasks people were actually doing.

The Approach

I led a mobile-first redesign grounded in contextual research. Observed staff on the floor, mapped real workflows, tested prototypes in the same environment the app would be used.

Three decisions shaped the outcome: a task-based interface, QR scanning for check-ins, and offline-first syncing for low-connectivity warehouse zones.

Key Design Decisions

qr_code_scannerDecision 01

QR Check-In

One scan replaces a multi-step process. Faster, no manual errors.

badgeDecision 02

Role-Based Tasks

Auto-assigned by role and location. No handoffs, no delays.

directions_runDecision 03

Workflow-First Nav

Structured around real tasks, not system logic. One step to find anything.

cloud_syncDecision 04

Offline-First Sync

Captures and submits data reliably in dead zones. Last adoption barrier, gone.

The Outcome

The app became the operational standard across Carsome's network within months.

  • Adoption: 75% → 98%
  • Vehicle lead time: 4.6 → 2.4 days
  • On-time check-in: 50% → 98%
  • Logistics planning accuracy improved, enabling better manpower and capacity forecasting.
